Several hundred pesticides of different chemical nature are currently used for agricultural purposes all over the world. Because of their widespread use, they are detected in various environmental matrices, such as water, soil, sediments, water and air. Pesticides are divided into many classes of which the most important is organochlorine compounds. Organochlorine pesticides are known to resist biodegradation and therefore they can be recycled through food chains and producea significant magnification of the original concentration at the end of the chain. Dichlorodiphenyltrichloroethane (DDT) and other chlorinated pesticides: aldrin, dieldrin, endrin and isodrin remain stable in the environment for many years (up to 40 years) after use. The long residence time of these substances in the environment has generated sustained interest in examining the pollution they cause. Although their use has been prohibited worldwide, the chemicals still find their way into local markets in developing countries where they are still used in diverse pest-control activities. Pesticide residues reach aquatic environment through direct run-off, leaching, indiscriminate disposal of empty containers, equipment washing, etc.
