Soil Pollution

<<–2/”>a >a href=”https://exam.pscnotes.com/soil/”>Soil Pollution is the Contamination of the soil by human and natural activities which may cause harmful effects on living beings.
This may be due to the following factors.

(i) Industrial wastes: Industries are the major causes for soil pollution Textiles, steel, paper, Cement, oil, dyeing and other industries are responsible for soil pollution. Toxic organic compounds and phenol destroy the fertility of the soil.
(ii) Biological agents – Fungi, protozoa, bacteria are important Biological agents for soil pollution. The human and animal wastes, garbage, waste water generates heavy soil pollution.
(iii) Radio active pollutants: Atomic reactor, nuclear radio active devices releases radio active pollutants. These pollutants enter the land and accumulate there by causing soil pollution.
(iv) Pesticides: Pesticides pollute the soil. There are of two types (i) chlorinated hydrocarbon insecticide (2) Organic phosphorous pesticides. Common chlorinated hydrocarbon insecticides are DDT, BHC.

Organo phosphorous insecticides are synthetic chemicals like Malathion and parathion.

DDT reduces the activity of sex HORMONES of male and female. The land with fungicides insecticides causes diseases to human beings.

Fertilizers: These discharge N, Na, K, S, Nitrates etc., into the soil. The nitrate causes cancer.

Polymer, Plastics & other water: These materials appear as garbage. Solid wastes and their quantities increase day by day. They pollute the atmospheres, land and also water badly.

Agricultural practices: Modern agriculture practices pollute the soil to a large extent. Today huge quantities of fertilizers, pesticides, weedicides are added to increase the crop field. Apart from these farm wastes, manure debris, soil erosion containing inorganic chemicals are causing soil pollution.
Effect of soil pollution
1.Organic wastes enter the soil pores and decompose. Pathogenic bacteria spread infection.
2.Compounds containing As, Hg, Cr, Ni, Zn and Fe are toxic to life.
3.Fluorides affect plant development
4.Water Logging and salinity increase the dissolved salt content in the soil. Some Plants are very sensitive to soil PH and salinity.
Thus land becomes unfit for Irrigation.
Control of soil pollution
1.Treat the sewage before land disposal
2.Rotate the crop pattern to allow the soil replenish the nutrients.
3.Preserve and protect top fertile soil, control soil erosion by tree plantation.
4.Fertilizers may be applied only after estimating the soil and crop measures.
5.Production of natural fertilizers Excessive use of chemical fertilizers and insecticides should be avoided. Bio pesticides should be used instead of toxic chemical pesticides.
6.Proper hygienic condition- People should be trained regarding the sanitary habits.
7.Recycling and reuse of waster – The wastes such as paper, plastic, metals, glasses should be recycled and used.,

Soil pollution is the contamination of soil with harmful substances. Soil pollution can be caused by a variety of factors, including:

Industrial waste: Industrial waste can contain a variety of harmful substances, including heavy metals, solvents, and pesticides. These substances can contaminate soil when they are not properly disposed of.
Agricultural runoff: Agricultural runoff is water that carries pesticides, herbicides, and fertilizers from farms into nearby waterways. This runoff can contaminate soil and water supplies.
Mining: Mining can release harmful substances into the Environment, including heavy metals, acid, and sediment. These substances can contaminate soil and water supplies.
Urban runoff: Urban runoff is water that flows over streets, parking lots, and other paved surfaces. This runoff can pick up pollutants, such as oil, grease, and gasoline, and carry them into nearby waterways.
Oil spills: Oil spills can contaminate soil and water supplies. The oil can also kill plants and animals.
Pesticides: Pesticides are used to kill pests, such as insects, rodents, and Weeds. However, pesticides can also contaminate soil and water supplies.
Herbicides: Herbicides are used to kill weeds. However, herbicides can also contaminate soil and water supplies.
Sewage: Sewage is wastewater from homes and businesses. Sewage can contain a variety of harmful substances, including bacteria, viruses, and parasites. These substances can contaminate soil and water supplies.
Radioactive waste: Radioactive waste is produced by nuclear power plants and other industries. Radioactive waste can contaminate soil and water supplies.

Soil pollution can have a number of negative effects on the environment, including:

Degradation of soil quality: Soil pollution can degrade soil quality, making it less productive for growing crops.
Loss of Biodiversity-2/”>Biodiversity: Soil pollution can kill plants and animals, leading to a loss of biodiversity.
Water Pollution: Soil pollution can contaminate water supplies, making it unsafe for drinking, bathing, and irrigation.
Air Pollution: Soil pollution can release harmful pollutants into the air, contributing to air pollution.
Human Health problems: Soil pollution can cause a variety of human health problems, including cancer, birth defects, and reproductive problems.

There are a number of things that can be done to prevent soil pollution, including:

Reducing the use of pesticides and herbicides: Pesticides and herbicides can contaminate soil and water supplies. Reducing the use of these chemicals can help to prevent soil pollution.
Properly disposing of industrial waste: Industrial waste should be properly disposed of to prevent it from contaminating soil and water supplies.
Managing agricultural runoff: Agricultural runoff can contaminate soil and water supplies. Managing agricultural runoff can help to prevent soil pollution.
Reducing urban runoff: Urban runoff can contaminate soil and water supplies. Reducing urban runoff can help to prevent soil pollution.
Preventing oil spills: Oil spills can contaminate soil and water supplies. Preventing oil spills can help to prevent soil pollution.
Cleaning up radioactive waste: Radioactive waste should be cleaned up to prevent it from contaminating soil and water supplies.
Restoring degraded soil: Degraded soil can be restored to its original condition. Restoring degraded soil can help to prevent soil pollution.

Soil pollution is a serious problem that can have a number of negative effects on the environment. There are a number of things that can be done to prevent soil pollution, and it is important to take steps to protect our soil Resources.

Soil pollution law and policy: There are a number of laws and policies in place to prevent soil pollution. These laws and policies regulate the use of pesticides and herbicides, the disposal of industrial waste, and the management of agricultural runoff.

Soil pollution research: There is a lot of research being done on soil pollution. This research is aimed at understanding the causes of soil pollution, the effects of soil pollution, and the best ways to prevent and remediate soil pollution.

Soil pollution monitoring: Soil pollution is monitored to track the extent of the problem and to assess the effectiveness of efforts to prevent and remediate soil pollution.

Soil pollution Education and outreach: There is a need for education and outreach about soil pollution. This education and outreach should target farmers, businesses, and the general public. The goal of this education and outreach is to raise awareness about soil pollution and to encourage people to take steps to prevent soil pollution.

What is soil?

Soil is a mixture of Minerals, organic matter, water, air, and living organisms. It is the foundation of our planet and supports all life on Earth.

What is soil pollution?
