“…For the extraction of PCBs from blood samples and their clean-up, the method of Jensen (5) with several modifications was used until 1978. The details of the analytical method were described in a previous paper (6). Blood samples obtained in 1979 and later were analyzed according to the method of Kashimoto et al (7) to determine not only PCBs but also related compounds, i.e., PCQs (polychlorinated quaterphenyls) and PCDFs (polychlorinated dibenzofurans).…”

Surveys of workers occupationally exposed to polychlorinated biphenyls (PCBs) in the production of thread or of paint, and of yusho patients were carried out from 1973 to 1982. PCB concentrations in the plasma of the workers ranged from 2 to 521 ppb, and some showed higher PCB levels in the plasma than typical Japanese yusho patients. Gas chromatographic patterns of plasma PCBs of the workers with high PCB levels were shown to match the patterns of the PCBs to which they had been exposed in the workplace. Japanese yusho children showed remarkable decrease with time, but no such decrease was observed in the yusho adults and the workers. Polychlorinated quaterphenyls (PCQs) were detected in the blood of typical Japanese and Taiwanese yusho patients, but PCQ levels in the plasma of the workers were below the detection limit of 0.02 ppb. Clinical findings and subjective complaints of the workers were usually slight compared with typical yusho patients, though some of them had mild dermal manifestations and their PCB levels were suspected to be related to serum triglyceride values. On the basis of these results, we discussed the relationship between the health status of the subjects and their contamination with PCBs or related compounds.

Fact-finding surveys of workers occupationally exposed to polychlorinated biphenyls (PCBs) in the production of silk thread or of paint were carried out. Some of the workers showed higher PCB levels in the plasma than typical yusho patients. Gas chromatographic patterns of their PCBs were shown to match the pattern of the PCBs to which they had been exposed. Levels of polychlorinated quaterphenyls in their blood were lower than 0.02 ppb. Medical findings were slight compared with typical yusho patients. From these results, the differences in contamination with PCBs and relevant compounds and in health status between these workers and yusho patients are discussed.
