Soil Pollution Facts

soil pollution and its causes

Soil that is not significantly polluted may still harm humans directly though , which according to , occurs when plants are grown in lightly polluted soil, which continuously absorb molecules of the pollutants. We are forced to keep soil in the form of its remnants or trash on our lands due to soil pollution. Soil pollution can also cause. It was found worldwide in fish and birds and was even discovered in the snow in the. This sad reality is not just restricted to developing countries, but highly developed and advanced countries as well. Smog is the result of fossil fuel combustion combined with sunlight and heat. Chronic exposure to , and other metals, petroleum, solvents, and many pesticide and herbicide formulations can be carcinogenic, can cause , or can cause other chronic health conditions.

Causes of Soil Pollution

soil pollution and its causes

Scientific studies, based on over 1000 samples from various sampling points, could not trace the source to fly ash and any sources from thermal power plants or industry as originally alleged. Pests include insects, plant pathogens, weeds, mollusks, birds, mammals, fish, nematodes roundworms and microbes that compete with humans for food, destroy property, spread or are a vector for disease or cause a nuisance. The harmful effects from pollution may come from direct contact with soil pollutants or from contact with other sources, such as water or food that has been grown or in contact with polluted soil. The chemicals then become the part of the air around us that all the living things take in. The result is a toxic gas which now surrounds our once pristine planet.

All the main types of pollution are: Air, Water, Soil or Land, Noise, Light, Radioactive, Thermal and Visual are the different types of Pollution. For example the burning of coal releases sulphur dioxide, a poisonous gas which is responsible for acid rain. Carbon Dioxide emissions increase air pollution. Life on earth exists in a very delicate balance, where soil, air, and water sustain not only human life, but the entire ecosystem. It is the nature who has created life on Earth. Our land on the other hand is living a nightmare too. These contaminate the soil by changing its physical and chemical properties.

soil pollution and its causes

Urban Wastes This cause is what feeds landfills. On this basis, the soil becomes unsuitable for crop survival or any other form of vegetation. It leads to many consequences for our Earth and without a plan to control it, those consequences might become irreversible. Following are the four most dangerous types of pollutions and their causes: Air Pollution Air pollution is perhaps the most common and the most dangerous type of pollution. Dispersion of acids and acid rain : Acids that enter the soil along with heavy metals or acid rain harm soil properties. Air pollution is also a cause of global warming and acid rain. Man-made soil pollution is usually caused by the improper disposal of waste coming from industrial or urban sources, industrial activities, and agricultural pesticides.

Soil pollution can negatively affect the metabolism of microorganisms and arthropods, which can destroy some layers of the primary food chain and have a harmful effect on predator animal species. Other issues that we face include increased temperature, unseasonal weather activity, etc. Southeast Water laboratory, Athens, Ga. Industrial Wastes Industrial pollutants are mainly discharged from various origins such as pulp and paper mills, chemical fertilizers, oil refineries, sugar factories, tanneries, textiles, steel, distilleries, coal and mining industries, drugs, and petroleum and engineering industries. This leads to a steep imbalance in the rain cycle.

Pesticides, herbicides, insecticides, increase the salinity of the soil, making it imperfect for crop bearing and adversely affecting the microorganisms that help the soil and plants function. Testing soil conditions will help the owner to decide if the soil is good for growing particular crops or if it is good for building and construction purposes. Plants, wildlife, humans and of course, the soil itself. When these changes occur, beneficial soil bacteria, microorganisms, nutrients, and the soil chemical process begin to deteriorate to an extent where they diminish the fertility of the soil. The United Nations General Assembly has designated this Day to reflect the adoption of Montreal Protocol on substances that deplete the Ozone layer. This technique also applies to dredging of containing toxins. Arable land is turning to desert and becoming non-arable at ever-increasing rates, due largely in part to and , lessening the hope that we can feed.

Soil contamination

soil pollution and its causes

These are getting exhausted at a very high rate. According to , soil pollution naturally contributes to air pollution by releasing volatile compounds into the atmosphere - so the more toxic compounds soil contains, the greater the air pollution it creates - and can lead to water pollution if toxic chemicals leach into groundwater or if contaminated runoff or sewage, which can contain dangerous heavy metals, reaches streams, lakes, or oceans. In fact, many pollutants that are more common in water or air pollution, can also cause soil pollution. This has good agricultural properties due to the high and content. The sun shining brightly on a naked planet is not the only source of radiation we are exposed to. Toxic chemicals that find their way into the soil can leach into the groundwater or can runoff into nearby streams, lakes, or oceans.

This is possible due to the complex soil environment, involving the presence of other chemicals and natural conditions which may interact with the released pollutants. In addition to using natural products, a ban should be placed on toxic chemicals. It is a process in which living organisms like bacteria and microbes are used to remove the noxious substances from the soil. Plants absorb what they need and the excess goes into the soil. Today pollution has become a very thoughtful topic to think. This means that humans who come into contact with these pollutants are far more likely to develop cancer. Since the plants can not naturally get rid of these contaminants, they accumulate in the plants system, causing an ever increasing amount of pollution.
