Abstract

The concentration and composition of PCB have been determined on various environmental materials, and the present study indicates the followings. Most of PCB in river and pond waters are adsorbed on suspended solids which are migrated and accumulated in surface sediments of river, pond and sea. The PCB dissolved in water is constituted by low chlorobiphenyl. The concentration and composition of PCB dissolved in rain water are similar to those in river water, but there are large differences between dust fall and air-born dust. PCB in rain water is probably derived from air, because the compositions of PCB in air and rain water are very similar each other. The following experiments have been performed to elucidate the mechanism of PCB pollution in environments: the amount and composition of PCB evaporated from water to atomosphere, and the adsorption on kaolin water. Some idea was proposed on the geochemical cycle of PCB from the present investigations and experiments.
