Organochlorine pesticide residues in human fat in the United Kingdom 1976-7.

Abstract

results from earlier studies showed a further decline in residues of pp'-dichlorodiphenyltrichloroethane (pp'-DDT) and dieldrin (HEOD) and increased amounts of hexachlorobenzene residues; concentrations of other compounds were similar to those observed in the studies carried out in 1963-4, 1965-7, and 1969-71. Comparison of the data with those from other countries showed that the concentrations of organochlorine pesticide residues and polychlorobiphenyls in human fat samples from residents of the United Kingdom remain among the lowest in Europe and, indeed, the world.

Specific accumulation and elimination kinetics of tris(4-chlorophenyl)methane, tris(4-chlorophenyl)methanol, and other persistent organochlorines in humans from Japan.

“…Our data provide one of the most up-to-date contamination status reports on PCBs in Japanese human adipose tissue, and these elevated residues suggest continuing exposure to PCBs by Japanese humans. In fact, temporal trend investigations conducted in developed nations such as the United States, Canada, the United Kingdom, the Netherlands, and Japan revealed that there was no significant decline in PCB residues in humans (16)(17)(18)(19)(20). PCB production ceased in Japan in 1972; however, large proportion of PCBs, accounting for approximately > 50% of the cumulative production, still remained in use in older transformers and capacitors (21).…”
