説明
In order to develop a bioaccumulation model which predict the levels of hazardous chemicals in food chain of sea area, we carried out the surveys in Tokyo Bay to examine concentrations of coplanar-PCB (Co-PCB). crude fat levels and so on in fish (conger-eel : Conger myriaster and Japanese whiting : Sillago japonica). From these research data, we could discuss about bioaccumulation profiles of Co-PCB of living fish in Tokyo Bay. As the results of discussion, the profiles were presumed as follows. • The bioaccumulation levels of Co-PCB in conger-eel and Japanese whiting are risen with their age. but the level of fat does not affect to the increase of accumulation of age-related Co-PCB. • In ihe conger-eel inhabiting Tokyo Bay. the Co-PCB is mainly distributed in that fat. • The lower fat fish inhabiting Tokyo Bay has higher concentration of Co-PCB in crude fat unit. • In the conger-eel and Japanese whiting inhabiting Tokyo Bay. the accumulation rates of Co-PCB congenr which have 5 or 6 chlorine atoms are higher than that of Co-PCB congeners which have 4 or 7 chlorine atoms. • Non-ortho PCBs have lower accumulation rate than mono-ortho Co-PCBs. • In the Co-PCB congeners which have same number of chlorine atoms, a Co-PCB congener which has higher water solubility has higher accumulation rate.
