What is DDT?
Dichlorodiphenyltrichloroethane (DDT) is an organochlorine substance, which was first synthesized in 1874, however, its insecticidal properties were discovered in 1939. DDT has been one of the most widely used pesticides in the world, its use reached its peak between 1946 and 1972. Today, DDT continues to be used in the fight against malaria and other diseases. Production is ongoing and obsolete stockpiles of DDT are in need of sound management.
Hazardous effects
DDT and its metabolites bioaccumulate in fatty tissues of humans and animals. Concentrations far above the World Health Organization (WHO) safety levels have been detected in human milk worldwide (DDT shows the highest concentration levels of all POPs). DDT is classified as ‘probably carcinogenic’ to humans and strong evidence shows that DDT can supress the immune system and disrupt sex hormones: high intake of DDT has been associated with developmental and reproductive abnormalities. Its stability, its persistence, and its widespread use have meant that DDT residues can be found everywhere, even in the Artic and Antarctic, open oceans and high mountain areas. Among the most affected animals are birds, because DDT causes eggshell thinning. Moreover, DDT is acutely toxic to fish and marine invertebrates.
