Write any two causes of soil pollution.

2

Answer

· Based on the official syllabus and past papers
Updated

Soil pollution is caused by various human activities and natural processes. Here are two major causes:

  1. Use of Chemical Fertilizers and Pesticides Excessive use of chemical fertilizers and pesticides in agriculture introduces harmful chemicals into the soil. These chemicals, such as nitrates, phosphates, and synthetic pesticides, accumulate over time, disrupting soil fertility and harming beneficial microorganisms. They can also leach into groundwater, contaminating water sources.

  2. Industrial Waste Disposal Improper disposal of industrial waste, including heavy metals (like lead, mercury, and cadmium) and toxic chemicals, pollutes the soil. Factories often dump untreated waste into open lands or water bodies, which eventually seeps into the soil. This contamination makes the soil infertile and poses serious health risks to living organisms.
