Organochlorine pesticides are synthetic compounds once widely used as insecticides and fungicides. They are extremely environmentally persistent, travel long distances and have high bioaccumulation potentials. In the 1960s, their potential to cause severe health effects was recognized. Since then, a number of organochlorine pesticides have been globally banned and are controlled under an international agreement (the Stockholm Convention). Organochlorine pesticides are sometimes referred to as legacy pollutants.

The human population is mainly exposed to organochlorine pesticides through dietary uptake. Possible health effects include skin disorders, reproductive dysfunctions and cancer.
