    Abstract:
    In this study, we analyzed PCB and PCQ concentrations in the subcutaneous fat tissue of residents of Nagasaki Prefecture, and compared these levels between the blood and subcutaneous fat tissue of people living in various parts of the prefecture. Seventy-one inhabitants were examined. In the blood, PCB concentrations in Tamanoura and Fukue were significantly higher than those in Nagasaki City. The CB% ratio in Tamanoura was significantly higher than that in Nagasaki and Isahaya. PCQ concentrations were below detection level except in one case. PCB concentrations in fishery areas showed higher levels than urban or agricultural areas. PCB concentration in the subcutaneous fat tissue was 100 times higher than that in the blood. PCQs could be detected in almost all of the subcutaneous tissues, but there was no regional difference in the PCQ concentration.
