Question

what are the different ways in which soil gets polluted?

Answer 1

Soil contamination or soil pollution is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals, or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene), solvents, pesticides, lead, and other heavy metals.The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapors from the contaminants, and from secondary contamination of water supplies within and underlying the soil. Soil contamination can be caused by:

Application of pesticides and fertilizer
mining and fuel dumping
Disposal of coal ash
Leaching from landfills
Drainage of contaminated surface water into the soil
Discharging urine and faeces in the open

Answer 2

Answer:

Agricultural sources and non-agricultural sources are both responsible for soil pollution.

Explanation:

Agriculture sources

• Agriculture and animal husbandry are two examples of the many industries that contribute to soil degradation. Soil pollution is caused by some agricultural practices.
• They include the usage of fertilizers, long-lasting insecticides, herbicides, fungicides, nematocides, and other chemicals, as well as animal wastes.

Non-agricultural sources

• The main cause of soil contamination from non-agricultural sources is typically urban sprawl, which is brought on by our modern way of life's high waste production per capita and quickly growing population.
• Materials from it that make it into the soil system have a long persistence, accumulate in dangerous concentrations, and become pollution sources as a result. Among the most significant soil contaminants are inorganic hazardous substances.
