Abstract

There are enormous work have put forward PCDD/Fs concentrations, toxicity, effect, population status as for cormorant as concern in USA, Canada and European nations(1, 2). However, there is no work relate with PCDD/Fs and dioxin-like PCBs in common cormorant collected from Japan excluding common cormorants of Lake Biwa, Shinobazu pond and Odaiba, Japan(3) in which they reported only dioxin-like PCBs but not PCDDs and PCDFs. According to their pioneer work, elevated concentrations of PCBs have been observed. 

Therefore, in present study, common cormorant collected from Tokyo Bay, Japan was used to determine concentrations of PCDD/Fs, in liver and egg and their diet samples of 3 different fish species. Since, diet samples included in this study provided biomagnification potential of cormorants. Eventually, toxic equivalency factor was also determined in liver and egg of cormorants using WHO- bird’s TEF values(4). This is the first study of this kind to be undertaken in cormorant of Japan for PCDD/Fs.
