Organochlorine insecticides and PCBs in water, sediment, and fish from the Mediterranean Sea

Organochlorine insecticides and polychlorinated biphenyls (PCBs) are world-wide distributed organic pollutants. Such compounds are characterized by their stability for long periods and may lead to marked changes in the aquatic ecosystem. In egypt and some other Mediterranean countries, wastewaters are discharged into the sea directly, or via agricultural drains. This work aims to assess the prevailing levels of organochlorine insecticides and PCBs in the sea water, sediments and some fish species collected at Port-Said. This location was selected as an example of an important recreational area, characterized by high fish productivity, growing industrial and navigable activities.
