Dichloro-diphenyl-trichloroethane (DDT) is a non-biodegradable pollutant. It was used as an insecticide in agriculture. It was banned globally for agricultural use under the Stockholm Convention on Persistent Organic Pollutants which has been in effect since 2004. In many countries, DDT is still used to control mosquitoes that spread malaria.
