Residue of Organochlorine Pesticide and PCB in Humans / 日本農村医学会雑誌

ABSTRACT

Organochlorine insecticides (BHC, DDT, etc) have been used in massive quatities in Japan. But in 1971, the goverment put a ban on their use as insecticides. We continued the residue analyses of organochlorine insecticide in human bodies from 1971 to 1982. This paper deals with the results of our residue analyses from 1980-1982. In paralel, We have also continued to analyze the residue of PCB.<BR>(1) A total of 264 specimens have been analyzed for human mother milk, the adipose tissue, the liver, the kidney and the spleen.<BR>(2) β-BHC and pp'-DDE were detected from all of these specimens.<BR>(3) Over a span 12 years, the decrease of total-DDT was smaller than that of β-BHC.<BR>(4) In the adipose tissue, there were no signs of a decrease in total DDT.<BR>(5) PCB was detected from all specimens of mother milk, the adipose tissue and the liver.<BR>It is conceivable that the pollution of human bodies by BHC, DDT. PCB, and other chemicals will last for a long time.<BR>There is a need to keep constant surveillance over the tendency of these chemicals in the environment and human bodies.
