Soil Pollution Essay In English 150 Words

Soil is a vital element of this planet, and it is directly connected to our survival. The pollution of this precious element has now turned into a global problem and not the only country’s concern.

Soil pollution can be defined as the increase of persistent toxic elements in the soil like the presence of chemicals, salts, disease-causing agents, radioactive wastes, or anything that changes the soil’s quality and causes an adverse effect in the growth of the plant and on human health.

“Don’t pollute our motherland- the only fertile land in this universe.”

Soil pollution can be reduced by proper regulated waste dumping and by avoiding littering, reduced use and throwing of toxic material, recycling of waste materials, decreasing the use of toxic fertilizers, pesticides, insecticides, and instead opting for organic products, stop deforestation by growing more plants (reforestation).

It is our role as students to understand the importance of preserving the purity in soil and saving it from contamination by educating others on the matter through the spreading of awareness. we will soonly update Soil Pollution essay in Hindi, Kannada, Punjabi and Telugu.

200 Words Essay Soil Pollution

Soil is the uppermost layer in the earth’s stratum. Soil enables and sustains life on the planet, without which there would be no living beings on the earth.

But lately, due to mans’ greed and irresponsibility, soil pollution has become a dangerous phenomenon, if not controlled would lead to catastrophic effects our atmosphere and food cycle in the future.

Soil pollution has been a problem ever since rapid industrialization and globalization. Governments, as well as people, should come forward to implement robust laws and policies to prevent soil pollution from happening further.

“Forming Pollution Is Easy, But Resolving The Impact Of It Is Difficult”

Wrong agricultural practices, dumping of harmful wastes, and garbage disposal on open lands, rupturing of underground storage tanks, industrial waste disposal are some of the many reasons that are causing soil pollution.

A polluted soil, which has no nutrients and useful chemicals in it, is no use to human beings, plants, and animals, resulting in leaving behind that land and searching for newer ones. This search for a new piece of land in order to cultivate it results in deforestation.

Deforestation will further result in soil erosion, melting of glaciers, global warming, floods, and various other calamities. Every chain is linked with one and another in nature and disturbance in one of the links will result in a disturbance in the whole chain.

Soil Pollution Essay In 250 Words

Introduction:

Adding any toxic substances to the environment is termed as pollution. Contamination of the naturally occurring pure soil with toxic substances is called soil pollution.

Soil pollution is the major affecting factor of our environment in the present scenario. Affecting soils by using chemicals, non-biodegradable wastes, industrial effluents, and artificial fertilizers will result in soil pollution.

10 Causes of Soil Pollution:

1) Industrial waste:

Industries are by far the worst polluters of the soil with all the chemicals they release into the environment be it in liquid or solid form.

2) Deforestation:

Clearing of trees leaves soil exposed to the elements so they are easily carried away by soil erosion. This leaves land barren and incapable of supporting vegetation.

3) Excessive use of fertilisers and pesticides:

The increased demand for food has forced farmers to use fertilisers and pesticides that release nothing but toxins into the soil, killing useful microorganisms that are important in plant growth.

4) Garbage pollution:

Garbage that cannot be recycled is disposed of carelessly and this is not only an eyesore but pollutes the land. Some of this waste can literally take thousands of years to decompose!

5) Pesticides:

Before World War II, the chemical nicotine chemical present in the tobacco plants was used as the pest controlling substance in agricultural practices.

6) Chlorinated Organic toxins:

The harmful effect of DDT and other chemicals led to the introduction of less persistent organic and more-biodegradable substance such as carbamates and organophosphates.

7) Herbicides:

Slowly, the industries began production of herbicides like sodium arsenite (Na3AsO3), sodium chlorate (NaClO3), etc. Herbicides can decompose in a span of few months.

8) Inorganic Fertilizers:

Excessive use of inorganic nitrogen fertilizers leads to acidification of soil and contaminate the agricultural soil. Also known as agrochemical pollution.

9) Industrial Pollution:

The incorrect way of chemical waste disposal from different types of industries can cause contamination of soil. 

10) Urban Activities:

Lack of proper waste disposal, regular constructions can cause excessive damage to the soil due to lack of proper drainage and surface run-off. 

Effects of Soil pollution:

Soil pollution exerts irreversible and irreparable effects on the environment and its habitats.

  1. Quality of soil gets reduced.
  2. Quality of crops grown becomes inferior.
  3. Affects human health.
  4. Causes serious destruction in the biodiversity and ecosystem.
  5. Harms the water bodies on earth.

Plastic soil pollution:

We are all affected by plastic bags litter no matter where we live. We see plastic bags littered on our streets, stuck in our trees and floating in our rivers, dams and oceans.

The littering of Plastic bag is disrupting our finely balanced environment more and more each day. Our Terrestrial Wildlife is suffering daily.

Conclusion:

The soil is one of the major resources that we depend on for everything and anything. If the soil is depleted of its purity and fertility, there can possibly a threat to the human race.

Hence, it’s high time that we address on the issue on a serious note and educate people to avoid activities that pollute the soil.

“This land is our land,
save it from all types of pollution.”

Land Pollution English Essay 300 Words For Class 10

Introduction:

The various human activities and also natural factors are the various causes of land pollution. Besides, some of the causes of land pollution are the use of pesticides, agricultural and industrial waste, deforestation, growing urbanization, acid rains, and mining activities.

Furthermore, these activities not only cause damage to the soil but also the reason for various human and animal infections and diseases.

Types of Land Pollution:

1. Agricultural Land Pollution:

We use a lot of fertilizers as well as pesticides, fungicides, and insecticides on our agricultural land in a bid to maximize yields.

These agricultural inputs are all loaded with chemicals. The chemicals are effective in killing the pests and increasing production. But they also strip the soil of its minerals and other valuable compounds.

Moreover, they are harmful to animals, fish, birds, and useful microbes. In fact, some of the herbicides we use to eradicate weeds are so harmful that they can be deadly even when used in small amounts.

2. Non-biodegradable Solid Waste:

There is a lot of waste that is generated in our homes, schools, hospitals, shops, and even workplaces. Most of this waste is non-biodegradable. It can take up to millions of years to decompose completely.

Non-biodegradable solid waste includes metal, glass, and plastic products. This waste finds its way to the dumping areas, which in turn results in landfills.

Plastic products are especially the most notorious.
They pile up over time and it becomes very difficult to eliminate them.

3. Industrial Waste:

Another major source of land pollution is industrial wastes. These wastes include the following:

  • Chemicals
  • Plastics
  • Metals
  • Paints

Other industrial manufacturing byproducts and residues.

Industrial wastes are normally generated from agricultural produce processors, oil refineries, pharmaceuticals, construction sites, and energy producing power plants.

For example, power plants release chemical wastes and dispose them in landfills. These include coal, petroleum, and nuclear wastes. Construction sites, on the other hand, produce wood, metal, and plastic wastes, which make their way into landfills.

While energy producing plants burn fossil fuels and biomass, other industrial producers like oil refineries and pharmaceuticals use various raw materials that generate loads of chemical residues and byproducts.

And despite the fact that the disposal of industrial products is largely regulated, some of the waste still end up in the landfills.

4. Deforestation:

Land degradation and pollution also occur when we cut down trees to clear land for agriculture, construction, mining or other economic activities.

Deforestation leads to the total loss of the land’s value. Elimination of natural vegetation disrupts the ecosystem, adversely affecting various life forms.

Take forest areas, for example; trees absorb 20 percent of the heat from the sun’s radiation. In so doing, it protects and conserves the surface soils from detrimental degradation.

When you cut trees, you expose the earth’s surface to the sun’s intense heat and other harmful elements. This, in turn, leads to land pollution, soil degradation, and desertification.

5. Mining:

The extraction of materials and ores from under the Earth’s surface also contributes to land pollution. You know how that happens?

Mining degrades the quality of land. These include the extraction of metals, oil, coal, stones, stand, and mineral ores such as gold. When mining or quarrying, you normally have to clear the land surface and drill huge manholes and pits.

After mining, we leave the land completely defaced and exposed to erosion, which further whittles down its quality and value.

Top 3 effects of Land Pollution:

  1. Climate change, which causes an onslaught of disastrous problems, including flash floods and irregular rainfalls.
  2. Habitat shifting, where some animals are forced to flee where they live in order to survive. The endangerment and extinction of species in wildlife.
  3. An increase in wildfires, due to polluted areas often becoming very dry. Increased air pollution, which burning waste contributes to.

Effects of Land Pollution on human health:

Land pollution is really serious. But not just to the earth, to people too. Land pollution can cause many things to the human body. People can be exposed to toxic waste and chemicals. Land pollution is also caused by disposal of harmful toxic wastes.

Long term health effects can include chronic respiratory disease, lung cancer, heart disease, and even brain damage. Land pollution affects health and harms wildlife. The conditions of land pollution is very expensive. Land pollutions is really messing up how people live and how kids grow up.

Poisoning from land pollution can occur from batteries, and can intake sewage bone disease. In 1955 the great smog disaster in London caused four thousand people to lose their lives in just a few days, and by the smog disaster the land pollution really picked up.

Over 10,000 houses were filled of just trash just land pollution! The land, when contaminated with toxic chemicals and pesticides, lead to potentially fatal problems like skin cancer and the human respiratory ailments in particular. 

Land Pollution problems:

1. Cleanup:

Environmental remediation consists of removing pollution from the soil, groundwater or surface water. Bioremediation (microbes) and phytoremediation (plants) can be used to convert the pollutants into harmless products. These are natural solutions that need to be supported by in-depth actions.

2. Green agriculture:

Sustainable agriculture is essential as it is meant to control the impact on the cultivated environment, by minimizing the external contributions (phytosanitary products), by diversifying the cultures and by using biological treatments.

3. Sustainable forest management:

Conservation of the forests is key. Without the protection of the trees, the land becomes dry and starts to erode. Therefore, sustainable forestry or logging is crucial to saving the soil from pollution.

4. Proper waste disposal:

Be it for industrial or household waste, efficient waste disposal is one of the most effective ways of curbing land pollution. This especially applies to toxic and hazardous waste disposal.

Ways to Limit land Pollution:

This harmful pollution is on the rise of its all-time maximum. The government and organizations are working at their level best to minimize this pollution. But it is necessary that we should also contribute to it.

In addition, making some small changes in our daily life we can lower the amount of land pollution from the environment. Besides, here we are going to discuss some ways by which we can minimize land pollution.

Use biodegradable products instead of non-biodegradable, as they are easy to dispose of and are pretty much safe for the environment.

Also, start-using food that is pesticides and fertilizers free as their usage increases the farmers will reduce the usage of chemical fertilizers and pesticides in their fields.

Besides, if you have a garden or enough space in your home then start growing your own organic fruits and vegetables.

In addition, avoid packing of things as most of these things are made from non-biodegradable materials that take hundreds of years to dispose of.

Conclusion:

In conclusion, land pollution can only be controlled if with the government we also contribute to it. And our contribution requires us to use fewer amounts of products that cause land pollution. Also, we should make it our duty to sort out the waste and avoid the usage of non-biodegradable products.

“Stop Littering, The Earth is not your garbage can.”

400 Words Essay On Land Pollution Control

Introduction:

29% of the earth’s surface is made up of land on which plants animals and human beings live. Land pollution refers to the degradation of land, soil and its nutrients due to various human activities such as deforestation, urbanization, agriculture activities, etc.

The land consists of forests, mountains, rivers, lakes, cities, villages and other settlements. The land sustains life on earth. It is because of the land that we can produce food that sustains our growing population boom.

Also, forests that stand on land sustains all the living beings, from animals to plants and trees and even the grasslands.

When we refer to land pollution, we mean the degradation of land and its fundamental properties. these include removal of its nutrients, desertification and ultimately making it a barren land, which means that a particular piece of land cannot support life on earth. 

But in recent years, the land has been over-exploited by man because of his need and greed. There are plenty of reasons for the pollution of land, some which are.

Agricultural land pollution:

Agricultural activities have been a pivotal reason for the degradation of land. There are certain harmful agricultural practices that farmers follow in many countries that have led to this problem. Burning of land is one of the biggest causes of both land pollution and air pollution.

Burning of the land after harvest helps in regaining the nutrient in the soil. But this land will lose its original nutrient and humus capacity thereby turning it into a barren land after a few years.

This crop burning activity will also cause lots of air pollution because of the release of high amounts of carbon dioxide into the atmosphere. Statistics suggest that the high level of pollution in the capital city of India, New Delhi, is because of the crop burning activities in the neighbouring states.

Industrial land pollution:

With the increase in population, it has been difficult to control the expansion of cities. Metropolitan cities like Bengaluru, Mumbai or New Delhi has been increasing and gulping up its neighbouring towns due to lack of space within the cities.

The reasons for this rapid urbanisation are many, some of which are migration of people from rural to the urban area in search of a better livelihood, increase in market size for industries to open up, improvement in consumer demand and technological advancements. This has led to garbage disposal problems leading to massive exploitation of open lands.

Large factories, sky scrappers, airport, damns, bridges and other infrastructural development in the country are putting massive amounts to pressure on our lands.

To feed the growing population in cities, deforestation is taking place for agricultural purpose, to feed the growing thirst of our population, groundwater is getting depleted at an ever-increasing rate.

Land Pollution facts:

  1. According the United Nations, the United States disposes more than half of its solid waste in landfills. This amounts to over 110 million tons of waste per year and makes the US one of the top contributors to worldwide landfill waste.
  2. In 2008, the United States produced more than 250 million tons of municipal solid waste. Most of the waste came from residential homes.
  3. According to the Environmental Protection Agency (EPA), electronics waste is rapidly increasing and seriously contributing to land pollution. In 2005, more than 1.5 tons of electronic waste were dumped in landfills.
  4. Due to land pollution, the Earth loses approximately 25 billion tons of valuable topsoil each year.
  5. It takes at least 500 years for 2.5 centimeters of topsoil to regenerate, and the United Staes loses soil at a rate 17 times higher than it takes to generate new topsoil.
  6. Much land pollution is caused by agricultural activities, like grazing, pesticide spraying, fertilizing, irrigation, confined animal facilities and plowing.
  7. Excessive irrigation impacts water and soil quality by concentrating pesticides and harmful bacteria in the top layers of soil.
  8. Land-based pollution has threatened 22 percent of the Earth’s coral reefs.
  9. Up to 80 percent of land pollution is caused by energy production, food production and transportation.

Land Pollution causes:

1. Deforestation and Soil Erosion:

Deforestation carried out to create drylands is one of the major concerns. Land that is once converted into dry or barren land can never be made fertile again, whatever the magnitude of measures to redeem it is.

Land conversion, meaning the alteration or modification of the original properties of the land to make it use-worthy for a specific purpose, is another major cause. It hampers the land immensely.

Also, there is a constant waste of land. Unused available land over the years turns barren; this land then cannot be used. So in search of more land, potent land is hunted, and its indigenous state is compromised.

2. Agricultural Activities:

With the growing human population, the demand for food has increased considerably. Farmers often use highly toxic fertilizers and pesticides to get rid of insects, fungi and bacteria from their crops. However, with the overuse of these chemicals, they result in contamination and poisoning of soil.

3. Mining Activities:

During extraction and mining activities, several land spaces are created beneath the surface. We constantly hear about land caving in, which is nothing but nature’s way of filling the spaces left out after mining or extraction activity.

4. Overcrowded Landfills:

Each household produces tonnes of garbage each year. Garbage like aluminum, plastic, paper, cloth, wood is collected and sent to the local recycling unit. Items that can not be recycled become a part of the landfills that hamper the beauty of the city and cause land pollution.

5. Industrialization:

Due to an increase in demand for food, shelter, and house, more goods are produced. This resulted in the creation of more waste that needs to be disposed of.

To meet the demand of the growing population, more industries were developed, which led to deforestation. Research and development paved the way for modern fertilizers and chemicals that were highly toxic and led to soil contamination.

6. Urbanization:

We humans have been making permanent settlements for at least the past 10,000 years. Most of the cities and towns, and the infrastructure created, will remain with us for thousands of more years into the future.

Many of us may not classify human settlements as “land pollution;” however, urbanization marks a significant change to the landscape that can cause land pollution in a variety of subtle and not-so-subtle ways.

7. Construction Activities:

Due to urbanization, a large number of construction activities are taking place, which has resulted in huge waste articles like wood, metal, bricks, plastic that can be seen by naked eyes outside any building or office which is under construction.

8. Nuclear Waste:

Nuclear plants can produce a huge amount of energy through nuclear fission and fusion. The leftover radioactive material contains harmful and toxic chemicals that can affect human health. They are dumped beneath the earth to avoid any casualty.

9. Sewage Treatment:

A large amount of solid waste is leftover once the sewage has been treated. The leftover material is then sent to the landfill site, which ends up polluting the environment.

10. Littering:

Littering is a common problem, no matter it is a city or a rural region. People just throw their garbage on the ground without caring about the adverse effects on the environment.

A common instance is that people just throw their cigarette butt on the ground every time. Since cigarettes contain elements harmful to the environment, it leads to land contamination.

Land Pollution effects:

1. Soil Pollution:

Soil pollution is another form of land pollution, where the upper layer of the soil or the topsoil’s composition is damaged or becomes altered.

This is caused by the overuse of chemical fertilizers, soil erosion triggered by running water and other pest control measures, leading to loss of fertile land for agriculture, forest cover, fodder patches for grazing, etc.

The regeneration process takes at least 500 years for 2.5 centimeters of topsoil. The United States loses soil at the rate 17 times higher than it usually takes to generate new topsoil.

2. Groundwater Poisoning:

When harmful substances from industrial processes, chemicals are improperly disposed of on the land or in illegal landfills or storages, the chemicals and other substances could end up in the groundwater system.

The process is called leaching. It can happen on farms, industrial sites, and landfills and affect the health of animals, plants and also humans.

3. Drinking-Water Problem:

Drinking water is highly affected by land pollution. Nearly 50% of the world’s population does not have access to safe drinking water, and each year water-based diseases cause up to 10 million deaths.

4. Change in Climate Patterns:

The effects of land pollution are very hazardous and can lead to the loss of ecosystems. When land is polluted, it directly or indirectly affects the climate patterns.

5. Environmental Impact:

When deforestation is committed, the tree cover is compromised. This leads to a steep imbalance in the rain cycle. A disturbed rain cycle affects a lot of factors.

Most importantly, the green cover is reduced. Trees and plants help balance the atmosphere; without them, we are subjected to various concerns like Global warming, the greenhouse effect, irregular rainfall and flash floods, among other imbalances.

6. Effect on Human Health:

The land, when contaminated with toxic chemicals and pesticides, lead to potentially fatal problems like skin cancer and the human respiratory ailments in particular. 

Globally, 9,500 people are diagnosed with skin cancer every day. The toxic chemicals can reach our body through foods and vegetables that we eat as they are grown in polluted soil.

Land pollution also caused developmental deficiency in children. Chemicals, such as lead that are commonly found in contaminated soil and water, can impact a child’s cognitive development even when the exposure is very low.

7. Causes Air Pollution:

Landfills across the city keep on growing due to an increase in waste and are later burned, which leads to air pollution. They become home for rodents, mice, etc., which in turn transmit diseases.

8. Distraction for Tourists:

The city loses its attraction as a tourist destination as landfills do not look good when you move around the city. It leads to a loss of revenue for the state government.

9. Effect on Wildlife:

The animal kingdom has suffered most in the past decades. They face a serious threat with regard to the loss of habitat and natural environment.

The constant human activity on land is leaving it polluted, forcing these species to move further away and adapt to new regions or die trying to adjust. Several species are also pushed to the verge of extinction, due to no homeland.

10. Water Nutrient Enrichment:

Chemicals that are frequently used on agricultural farms, such as nitrogen, end up benefitting the crops only in a small proportion. The rest ends up in water populated by fish, algae, and other lifeforms.

As the nutrient-heavy water saps up most of the oxygen in the water, it leaves little oxygen for fish and other marine life. The water in that situation becomes unable to support most life forms.

11. Wildfires:

When land areas are polluted, they usually become quite dry. The dry conditions created by pollutants in the soil create the perfect environment for wildfires and increases the probability of wildfires dramatically.

The fires can grow quickly because of the dry conditions and widening area of polluted land, thereby harming the whole environment and killing plants, animals and even humans.

12. Habitat Shifting:

When deforestation and soil erosion are in progress, animals are forced to move from their natural habitat to find shelter and food. The change is too traumatic for some animals, and this even leads to loss of life. As a consequence, some species are posed with a greater risk of extinction.

13. Other Issues:

Other issues that we face include increased temperature, unseasonal weather activity, acid rains, etc. The discharge of chemicals on land makes it dangerous for the ecosystem too.

These chemicals are consumed by the animals and plants and thereby making their way in the ecosystem. This process is called biomagnification and is a serious threat to the ecology.

Effects of Land Pollution on the environment:

Land pollution can be one of the most visible types of pollution. You see trash outside of buildings or on the side of the road. You may see a large landfill or dump.

This type of land pollution not only can hurt animals and their habitats, but also is ugly and destroys the beauty of nature.

Other types of land pollution like mining, farming, and factories can allow for harmful chemicals to enter into the soil and water.

These chemicals can cause animals and plants to die, disrupting the food chain. Landfills release the greenhouse gas methane, which may lead to global warming.

When deforestation is committed, the tree cover is compromised. This leads to a steep imbalance in the rain cycle. A disturbed rain cycle affects a lot of factors.

Most importantly, the green cover is reduced. Trees and plants help balance the atmosphere; without them, we are subjected to various concerns like Global warming, the greenhouse effect, irregular rainfall and flash floods, among other imbalances.

Conclusion:

As much as oxygen is important for the survival of living beings on earth, the land is also necessary to sustain life. Without land, no living being can continue on this planet. Collectively, it becomes our responsibility to formulate strong and effective laws and regulations to prevent further land pollution.

It is not just the responsibility of governments or a corporate house, each individual citizen needs to take care of the environment to leave earth as a better place for future generations.

“Plastics give a helpful hand,
but they are polluting our land!”

Soil Pollution Essay 500 Words

Introduction:

Soil pollution is one of the major threat faced by our world and the main reason behind this issue is human activities.

Humans behave very irresponsibly when the fact comes to serving back to nature who provide us with many gifts and blessings.

The soil is the nature’s gift on which we live, walk, find the source for food, grow food, etc. But anything done in an excessive way becomes poisonous to the environment. Carefree use of soil has caused the increased soil pollution rate which eventually will make the land unusable and non-recyclable.

Ground Pollution:

This invisible affliction appears when the concentration of pollutants on the surface becomes so high that it harms land biodiversity and endangers health, particularly through food.

Activities such as stock breeding and intensive farming use chemicals, pesticides and fertilisers that pollute the land, just as happens with heavy metals and other natural and man-made chemical substances.

Soil or Ground pollution is a global threat that is particularly serious in regions like Europe, Eurasia, Asia and North Africa, as indicated by the Food and Agricultural Organization of the United Nations (FAO).

The FAO also affirms that both intense and even moderate degradation is already affecting one third of the world’s soil. Moreover, recovery is so slow that it would take 1,000 years to create a 1 centimetre layer of arable soil.

Remediation of heavy metal contaminated soil:

  1. Various remediation methods have been developed for heavy metal-contaminated soils.
  2. In-situ, contaminant removal/extraction remediation techniques are more favorable.
  3. The methods landfilling, soil washing, and solidification are well established.
  4. Electrokinetic extraction, chemical stabilization, and phytoremediation are immature.
  5. Treatability studies are crucial to selecting feasible soil remediation techniques.

Abstract:

Soil contamination by heavy metals constitutes an important environmental problem, whereas field applicability of existing remediation technologies has encountered numerous obstacles, such as long operation time, high chemical cost, large energy consumption, secondary pollution, and soil degradation.

Here we report the design and demonstration of a remediation method based on a concept of asymmetrical alternating current electrochemistry that achieves high degrees of contaminant removal for different heavy metals (copper, lead, cadmium) at different initial concentrations (from 100 to 10,000 ppm), all reaching corresponding regulation levels for residential scenario after rational treatment time (from 30 min to 6 h).

No excessive nutrient loss in treated soil is observed and no secondary toxic product is produced. Long-term experiment and plant assay show the high sustainability of the method and its feasibility for agricultural use.

Soil Pollution facts:

Soil pollution happens when soil contaminants exceed a certain threshold amount that could pose a risk to human health and ecosystem or are simply above the natural background levels.

Soil pollution can affect humans through inhalation, direct skin contact, the consumption of poisoned vegetables and fruits grown on contaminated ground, as well as the use of or contact with the poisoned groundwater below the soil that circulates back on the ground. Exposure to the toxic compounds generated as a result of soil pollution can lead to various medical conditions.

Over time, what may have started as tiny amounts can reach considerable concentrations depending on environmental conditions (including soil types) and degradability of the released contaminant, and resulting in soil poisoning.

For example, metals are not degradable and may accumulate and concentrate in surface soils over time. However, not all metals behave similarly. A few metals can infiltrate into deeper soils, especially if precipitation is high (arsenic is one such example), while many other metals will stick to surface soils and become adsorbed by soil particles.

Causes of Soil Pollution:

One type of action that causes soil pollution is the excess use of fertilizers. The development in the field of agriculture to produce more amount of crops within the time limit without the crop getting affected by external and internal factors introduced the chemical fertilizers in the market. These chemical fertilizers used in an uncontrolled manner will eventually destroy the natural fertility of the soil and make it a wasteland over time thus causing soil pollution.

The same goes with the pesticides, insecticides, herbicides, etc. These chemically produced materials for keeping insects, and other small living beings away from the crop, living area, etc., are really harmful to our land. They gradually suck away all the goodness in the soil which results in the destruction and causes soil pollution.

Industrialization is another cause of soil pollution. The excessive production of industrial waste that gets disposed on land will make the soil inappropriate for further use as it will be contaminated with the chemicals from the waste. Not only wastes from factories but also the homes and the other biological wastes create soil pollution like plastics, unprocessed biological wastes, etc.

Not only physical wastes affect the soil and results in soil pollution but also the radioactive ones. The radiations from different industries and works like mining, nuclear energy processing, etc., are a major threat to the soil that causes soil pollution.

Soil erosion is a natural cause that results in soil pollution. This natural disaster washes away all the goodness in the soil and makes it a wasteland inappropriate for any kind of usage and also contaminates the soil with other wastes too.

Effects of Soil Pollution:

All these industrial, urban, radioactive and biological wastes thrown on soil without processing and management will cause soil pollution to a massive amount and threatens the life of the human, animal and other living beings who all depend on the land in one way or the other.

All these contaminations in the soil are eventually transformed into the crops, plants and other products we cultivate on the land.

The chemicals from the wastes, radiations, etc., are absorbed by the roots and this chemically contaminated food is consumed by animal, birds, human, etc. This consumption will cause many types of diseases, physically and mentally, to the living race.

The chemically concentrated fertilizers and pesticides used for better production of crops is actually a curse to the living being eating them.

Soil pollution due to this type of chemicals causes physical and mental disabilities in human. Even the new born child get affected by soil pollution making them grow disabled and retarded.

Soil pollution should be controlled and otherwise, every living being will be facing a big disaster that will eventually destroy everything once we had.

Health Effects of Soil Pollution:

Soil that is polluted or contaminated affects the health of human directly. When there is a contact directly with the soil or through inhaling of the vaporized soil contaminants a greater threat is posed through soil contamination infiltrating into the groundwater aquifers that are used by humans for consumption. Some of the effects of soil pollution on health include skin rash, eye irritation, fatigue, nausea, headache, liver conditions, kidney problems and leukaemia.

Treatment of Soil Pollution:

Polluted soils are sometimes excavated and either treated, disposed of or replaced with clean soils. Excavation is used where there is buried debris or old drums of chemicals. “In situ,” or on-site, treatments may include chemical, biological, electrical or thermal treatment.

Differently from the atmosphere and water, which decontaminate quite rapidly, the soil, although it has a high self-treatment capacity thanks to chemical, physical, and biological mechanisms, keeps contaminated for a long period. It was noticed that, in order to significantly reduce the content of heavy metals in a polluted soil, the quantity of water corresponding to tens of years of rain is not sufficient.

The presence of polluting compounds in the soil, especially highly toxic ones, can represent a risk for human health and for the environment, and requires reclamation activities. The reclamation of a land can be based on the inactivation or degrade of pollutants (they are transformed into less dangerous or not dangerous substances) or their removal by using chemical, physical or biological treatments.

Reclamations is normally done on agricultural land and areas close to industrial zones or abandoned dumps. Keep the lawn in your yard well vegetated and irrigated in order to reduce any health risks coming from soil poisoning. Evaluate and test the soil of your garden for pollution through accumulation.

Best Speech on Land Pollution:

Soil or land pollution can be defined as the “changes in physical, chemical and biological conditions of the soil through man’s intervention/misuse of land and hence resulting in degradation in quantity and productivity of the soil. Soil is made of both inorganic and organic substances.

These coarse particles cover the top surface of the earth. The organic portion of the soil consists of the dead remains of plants and animals, while the inorganic part is made up of rock fragments and minerals. The process of formation of soil is thousands of years long, and it is our moral duty to save this vital component of nature from all kinds of pollution.

Conclusion:

Soil pollution is the lowering of the quality of soil through the different natural processes and man’s actions that makes the soil not fit for the production of crops. Soil pollution is being caused to a large extent by the population of humans that is increasing and also the advancement in the lives of humans.

The major causes of the pollution of soil are forest fires, soil erosion that is excessive, pesticides (herbicides and insecticides), chemical fertilizers, biocides, deforestation, over irrigation, water logging, water irrigation that is untreated, drought, leaching, industrial and urban waste, etc.

Studies have shown that soil pollution is increasing at a very alarming rate in urban and rural areas alike. Research has shown that the amount of fertilizers (chemicals) that is used by farmers have increased by about five million tons between 1980 and 1981 and by about eighteen million tons between 1990 and 2000 in a bid to increase the production of crops.

These chemicals that are toxic get into the body of human from the food chain bringing harm through the cause of physical deformities and defect of neural tubes in babies that are new born.

“Join the revolution,
Avoid the retribution,
Make a resolution to stop pollution.”
