They are animal wastes, use of long lived pesticides, herbicides, fungicides, nematocides, etc. Extraction and processing of mineral ores weakens the surface of the soil. The problem arises when their unnecessary pile is dumped on the fields and this organic debris starts to decay by rain water. Biological agents such as bacteria, fungus, viruses, and protozoa are a major source of soil pollution and these are mostly spread through the discharge of human and animal waste which is a major source of soil pollution. As much as it’s an alternative method of addressing the impacts of soil pollution, emphasis should be on recycle, reuse, and reduce. Industrial wastes or byproducts are among the leading causes of soil pollution. The root cause of soil pollution is often one of the following: Agriculture (excessive/improper use of pesticides) Excessive industrial activity. Origin and sources of soil pollution The origin of contaminants in the ecosystems may be natural or anthropogenic. In order to increase productivity, humans have been using chemical fertilizers and pesticides. In this method, the technique of solvent extraction is used. There are many types of chemical substances in the waste dumped by the industry on the ground. All the radionuclides deposited on the soil emit gamma radiations. Most of these chemicals are non-biodegradable, while others decompose to products that are toxic to soil. Natural processes that result in an input of pollutants can be the weathering of ore bodies (inorganic pollutants), volcanic activity or forest fires (inorganic and organic pollutants). These substances include artificial chemical pesticides, herbicides, fungicides, and fertilizers, as discussed below: The introduction of modern pesticides, herbicides, and insecticides has resulted in an increase in the use of agricultural chemicals. Rainwater carries Sr-90 and Cs-137 to be deposited on the soil, where they are held firmly with the soil particles by electrostatic forces. Biological agents such as bacteria, fungus, viruses, and protozoa are a major source of soil pollution and these are mostly spread through the discharge of human and animal waste which is a major source of soil pollution. Deserts, infertile large agricultural lands, hilly areas devoid of vegetation are the result of soil erosion.

A true environmentalist by heart ❤️. Planting more tree cover is the best way of reducing soil pollution by minimizing erosion and the effects of floods. Mining and forestry activities that clear the land surfaces (clearcutting) and use ‘skid trails’ often leave the land unrestored. For all these reasons, the productivity becomes low and the vegetation cover is reduced. Where there is a will there is a way essay, Environmental Problems That Our World is Facing Today, Loss of Biodiversity: Meaning, Causes, Effects and Solutions, Smog - Types, causes, Ill-effects and how to prevent, Ocean Acidification: Meaning, Facts Causes, Effects and solutions, Due to the imbalance between the atmospheric deposition and leakage with rain water, the natural accumulation of compounds takes place in the soil (accumulation of perchlorate in dry environment). Erosion of the soil containing some traces of mineral ores and fine materials around the mining areas results in sediment loading in the water sources and drainage ways. container: 'taboola-right-rail-thumbnails', Soil gets a large amount of human, animal and bird excreta, which constitute a major source of land pollution by biological agents. People should be trained regarding sanitary habits. Most of these wastes contain residues of toxic inorganic and organic chemicals, which are extremely harmful. Open dumping is the most commonly practiced technique. The microbes are collected, cultured, and used to treat the environment. Today, there is an urgent need to save this limited resource from pollution to ensure adequate availability of habitats and food items. It is done regularly to ensure that the detoxification process is complete. Soil pollution refers to an undesirable decrease in the quality of soil, either by man-induced sources or natural sources or by both. Per capita quantities of domestic waste depend on economic status and social development. Household waste includes food scraps, old newspapers, and plastic items, bottles, wood, glasses, cans, old tools, tyres, worn out furniture, broken toys and many other substances. Contaminants can be removed by evaporation. Doing so can help to improve soil health, and reduce erosion, runoff and soil compaction, and therefore the chance of nutrients reaching waterways through runoff. fertilizers and some agricultural practices. Chemicals such as phosphate and nitrogen are polluting the environment, groundwater resources and the soil. Soil pollution is a complex phenomenon, and it can be triggered by a variety of things and activities, from the littering of cigarette butts to excess use of chemical fertilizers. The importance of soil increases even more when we already know that only two percent of the globe has agricultural land. In developing countries, the pollution levels are even higher because activities such as gold mining are done using traditional methods, which lead to the release of mercury and other heavy metals into rivers and neighboring lands.

Soil erosion is a very slow process in nature, but its results are far-reaching and widespread. Integrated waste treatment methods should be adopted. Mining sources: This includes piles of coal refuse and heaps of slag and underground debris. Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics (human-made) chemicals or other alteration in the natural soil environment. Soil acts as a filter and buffer for contaminants, but its potential to cope is finite. While soil pollution traditionally has not received the same attention as issues like tree-planting, global momentum picked up in 2018, when the Food and Agriculture Organization of the United Nations (FAO) published a ground-breaking study: Soil Pollution: A Hidden Reality. The pollution of the soil is either caused by natural activities or human actions that destroy its properties, such as structure, composition, and soil biota. What is more, the materials used to manufacture fertilizers contain impurities that add to soil toxicity. the ecosystem. Some plastics and glass can be recycled to lessen the volume of wastes and encourage environmental conservation. Radiation -106 and Rhodium -106, Iodine-131, Barium-40, Lanthan-40, Serium-144, etc, reach the radioactive waste and mud produced by nuclear testing laboratories. Most potentially harmful substances, however, end up in soils as a result of human activities. The speed at which the population of the world is increasing today, soil is being exploited beyond limits to arrange for food. Domestic and Municipal Wastes: Major issues about … mode: 'thumbnails-rr', These natural compounds (contaminants) rarely build up to generate pollution. Others are non-biodegradable, which means they can persist in the soil for a long period. The exposed soil is easily eroded and exposed to artificial chemical pollutants from the air, wind, and rain. These chemical pollutants or bioactive chemicals are also called Creeping Deaths. Deforestation of the upper surface of the soil in mountainous districts is increasing rapidly which compels the farmers to increase the use of urea. Soil pollution also has an impact on the quality of water and air. Soil pollution is increasing due to increased amount of domestic waste. The domestic wastage mainly includes dry wastes and wet leftovers of kitchens. Due to chemical fertilizers and bio-chemical chemicals, an imbalance in the entire ecosystem is created. Pesticides are the most common cause of soil pollution. Recycling paper, plastics and other materials reduces the volume of refuse in landfills, another common cause of soil pollution. Ex: Lavatories should be equipped with quick and effective disposal methods. This process is experimental and the keywords may be updated as the learning algorithm improves.

To reduce soil pollution, there is a need to adopt the Reduce, Reuse, and Recycle strategy. Soil Pollution: Global Scenario If the capacity of the soil to mitigate the effects of contaminants is exceeded, the soil turns into a time bomb that can pollute other compartments of the environment. Soil is the home of a huge number of organisms. Excessive farming, destruction of forests, excessive grazing by animals too increase soil erosion. If the levels of these radiations exceed a given limit, they lead to disastrous effects. In highly industrialized countries, domestic and municipal wastes comprise a fraction of total waste. Every cause is linked with another. 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. Large scale industrialization and urbanization, the increasing population in the cities and the emerging fluid and solid residues are polluting the soil. Carbon dioxide, nitrogen dioxide, sulfur dioxide, and carbon monoxide are some of the gases produced from industrial activities that cause considerable pollutionto soil indirectly. The disposal of industrial solid wastes is the major source of soil pollution … As a result of such kind of pollution in the soil, the growth of crops and plants decreases. Soil contamination or soil pollution can occur either because of human activities or because of natural processes. “Activities linked to transportation in and around urban centres constitute one of the main sources of soil pollution. They end up in the soil through irrigation and flowing stormwater. Improper disposal of wastes from nuclear reactors containing Ruthenium-106, Iodine-131, Barium140, Cesium-144 and Lanthanum-140 along with primary nuclides Sr-90 with a half-life 28 years and Cs-137 with a half-life 30 years can, therefore, result in soil pollution and contamination. Soil pollution takes place due to fertilizers, insecticides and pesticides used in the fields. (And How to Keep Them Away), Do Deer Eat Peonies? So, the more the toxic contaminants in the soil, the higher the level of toxic particles and foul gasses emitted into the atmosphere. Try to use biodegradable products as much as possible. Any unwanted change in physical, chemical or biological properties of the soil, which impacts humans and other organisms or the soil’s natural quality such as fertility and utility, is called soil pollution. Pests and diseases in crops can also be controlled through the use of biological methods, consequently reducing soil pollution. be agricultural pollution, Industrial wastes . Municipal waste includes garbage removed from homes; human excreta, waste of fruits and vegetables thrown in markets, waste of various industrial organizations, plant waste of gardens, dung mixed with  fodder of animal shelters, garbage and sludge from street drains and gutters, and all kinds of litter generated from slaughter houses, butcher’s shop, fish market, poultry centres and leather research  institutions. Stream stripping is an example of such a method where a jet of steam is injected into the contaminated soil to cause evaporation of volatile pollutants. Small particles of the dust during construction activities can easily spread all through the air and slowly intermingle into the soil. In the soil, a natural source of these metals is bedrock. He headed the editorial team of 'Sahara Time', a 48-page general interest English weekly newspaper, and later, handled a 24x7 online wing Dry waste includes dust as a result of cleaning, waste paper, cardboard, wooden leaves, broken pots of glass or porcelain, vials, tin containers, hearth-ash, pieces of clothing etc. Fertilizers are mostly used to correct the deficiency of soil nutrients. Soil pollution is defined as the phenomenon of addition of various harmful chemicals, salts, microorganisms and other toxic substances into the top layer of the soil. Nuclear explosions and improper disposal of radioactive wastes should also be banned. The garbage is dumped anyhow and contains wastes such as food waste, plastics, industrial wastes, e-waste, and general household wastes. waste materials could be recycled and the organic materials disposed of in areas designated for natural decomposition. They contain hazardous chemicals which are absorbed by the soil and deliberately bring down the soil quality. People should be made aware through informal and formal public awareness programs on health hazards and environmental education. Additionally, another sources of the metals are plant protection products. Unless you strongly believe in Elon Musk‘s idea of making Mars as another habitable planet, do remember that there really is no 'Planet B' in this whole universe. It is also caused due to sewer lines leakage in the subsurface of soil. Humans have an unusually big hand in increasing the speed of naturally occurring erosion. Sewage plants also contribute to soil pollution owing to how they dispose of sewage sludge from domestic and commercial waste. Ex: Mass media, Educational institutions and voluntary agencies can achieve this. (And How To Keep Them Away). Causes of Soil Contamination. A soil that is deficient of potassium, calcium, nitrogen, and sulfur, among other important macro-nutrients, should be treated with the right fertilizer and at the right amount. Under the municipality, the entire city’s garbage can be found which leads to contamination of the soil. Sources of Soil Contamination There are many different sources of soil contamination. In nature, there are radioactive minerals that contribute to soil pollution such as radionuclides of radon-222 and Radium -226, Thorium, Uranium, isotopes of Potassium (K-40) and Carbon (C-14) are commonly found in soil, rock, water and air. It appears as if the urban administrators do not know that most of the non-biodegradable waste materials could be recycled and the organic materials disposed of in areas designated for natural decomposition. Sewer sludge may also contain high levels of metals, further polluting the soil. Residues of all these materials produce gases such as sulphur and nitrogen oxide. As a result, today the nutrient capacity of soil is decreasing at alarming levels. Natural factors due to which soil degradation occurs include volcanic eruptions, alterations in rainfall patterns, earthquakes, geographical changes, air pollution and melting of glaciers. Soil is vital not only for the growth of plants and growing food but also cultivating raw materials for agro-based industries. Founded Conserve Energy Future with the sole motto of providing helpful information related to our rapidly depleting environment. Diseases in humans such as dysentery, diarrhoea, plague, malaria and many other diseases are the result of indiscriminate dumping of waste. The mining process utilises heavy metals and many toxic chemicals such as sulphuric acid. TYPES, EFFECTS AND SOURCES OF SOIL POLLUTION Soil pollution mainly occurs due to the following: 1. Pinpointing at one particular cause is quite difficult. Soil pollution is synonymous with the problem of disposal of solid waste. google_ad_width = 300; De-forestation, the cutting down of … Most developing countries have a problem controlling the disposal of municipal garbage. After harvesting of crops, the remaining leaves, stalks, grasses, seeds etc, generally, do not lead to any serious pollution because these residues of plants are mixed in soil and are automatically decomposed by biological functions.
