Abstract

Toxic effects of organochlorines on wildlife on the top of food chain are a major concern during past few decades(1). Especially there is growing evidence that PCDDs, PCDFs and PCBs are harmful to wildlife, especially on predatory birds(2). Avians that occupy trophic positions at the top of food chains in aquatic environment have frequently been used as bio-indicators for toxic organochlorine compounds. 

There are so many reports that demonstrated concentrations of PCDD/DFs and PCBs in eggs and muscle tissue of avians in various parts of the world(3). Only very few documents have reported exposures of dioxin-like PCBs and PCDD/DFs in colonial -fish eating water birds in Japan(4,5,6). Nevertheless, there is not much work on PCDD/DFs and PCBs in livers of range of bird species. In this study we determined PCDD/DF and dioxin-like PCBs in livers Japanese birds with four ecologically different habitat.
