Organochlorine pesticides

Organochlorine pesticides are pesticides made out of organochlorine compounds They are chemically produced pesticides which include DDT, dieldrin, heptachlor and chlordane. Many types where widely used as insecticide throughout the 1950's and 1960's until their use were banned in western countries since the 1970's. Many organochlorine pesticides are extremely persistent in the environment. They have a low solubility in water and therefore tend to adsorb on to particles. They tend to accumulate in the lipids of living organisms which makes them difficult to excrete, which causes bioaccumulation.
