| Outline of Final Research Achievements |
Chlorophenylsilanes are PCBs produced unintentionally during the manufacturing of pigments and chemical products. It was observed that the specific congeners of PCBs had antagonistic activities on the estrogen-receptor (ER) α and β, mediated via 10 kinds of nuclear receptors. The dynamics of unintentionally produced PCBs in the environment were discussed. It was found that the effects of Kanechlor in the atmosphere and sediments were strong, and that the PCBs included in azo pigments have some effects. However, little pigment-derived PCBs were included in the blubber and liver of marine mammals.
