Soil pollution largely arises from the pesticides, insecticides and herbicides used to protect stored and growing crops from insects, rodents, weeds and disease. Since World War II, when DDT proved highly effective against disease-carrying insects, synthetic pesticide use has grown enormously — but repeated use of the same chemical selects for resistant pest populations, pushing the industry toward new, often more toxic classes such as Aldrin, Dieldrin, organophosphates and carbamates. Older organochlorine pesticides are water-insoluble and non-biodegradable, so they biomagnify up the food chain, reaching harmful concentrations in top predators including humans; newer organophosphates and carbamates are more biode …
