抄録

Residue of PCB, DDT and HCH in fish from lakes and rivers in the world was reviewed from the surveys in the years of 1995-2007. PCB and T-DDT concentrations in the fish from the lakes and rivers of America were relatively high, but those of Europe, Asia and Africa were relatively low. T-HCH concentrations in the fish were relatively low in both of the lakes and rivers in all the world. DDT was presumed to be used in Egypt, Tanzania and Brazil from the high percentage of pp’-DDT in the composition of T-DDT in the several kinds of fish from Lake Burullus, Lake Victoria and Ponta Grossa Lake. Technical HCH was presumed to be used in Japan, China and India from the low percentage of γ-HCH in the composition of T-HCH in the lake and the river fish in the countries. On the contrary, Lindane was presumed to be used in the countries of Europe and Africa from the high percentage of γ-HCH in the lake and the river fish in the countries. Half-lives (t1/2) of PCB and T-DDT in fish from lakes in Japan, USA and Sweden were calculated from the long-term monitoring data using an exponential decay model. The t1/2 values were 20years in Lake Biwa, 10years in Lake Ontario, 7years in Lake Michigan and 20years in Lake Storvindeln for PCB and 9years in Lake Biwa, 10years in Lake Ontario, 8years in Lake Michigan and 7years in Lake Storvindeln for T-DDT.
