"Aquatic Ecosystem Contamination and Riverine Flux of Persistent Organochlorine Pollutants (POPs) to Coastal Seas in the Asia-Pacific Region". November, 1996.

By Byron A. Bodo

A study commissioned by the UNEP GEMS/Water Programme in support of the Global Programme of Action for the Protection of the Marine Environment from Land-Based Activities.

This report documents the occurrence of selected POPs [persistent organochlorine pollutants] in the freshwater aquatic systems of the Asia-Pacific region. The region is defined herein to include Asian coastal mainland countries from Iraq to China, and the major islands of the Eastern Indian and Western Pacific Oceans. The POPs elected for study included the industrial chemical PCBs [polychlorinated biphenyls]; the insecticides DDT, HCH [hexachlorocyclohexane], chlordane, heptachlor, drins [aldrin, dieldrin and occasionally endrin]; and HCB [hexachlorobenzene]. All, except HCH, are members of UNEP's dirty dozen POPs list. HCH was added because it has been heavily used in the Asia-Pacific region since the early 1950s.
