There are 252 toxic chemicals in the revised Toxic Substances Control Act (TSCA) promulgated by Taiwan EPA. The purpose of this project is to establish a practical and appropriate toxic data bank as the basis of further related policy-making and policy-executing. Two approaches would be applied to accommodate this goal. The one was to conduct field studies and empirical measurements in various environmental media of the normal fields and nearby residents to explore the concentrations and distribution for those three selected chemicals, including polychlorinated biphenyls (PCBs), dibutyl phthalate (DBP), triphenyltin hydroxide. The other was to collect and analyze the survey report sponsored by research institutes and governmental institutes in the past ten years in Taiwan, combining with the data of spatial and temporal distributions, the concentration and allocation profile in various environmental media and humans can be elucidated for these toxic chemicals. In this research, PCBs, DBP, and triphenyltin (TPhT) were select to investigate environmental distribution in the river and harbor environment. 368 PCBs and DBP in the sediment and water of nine river, triphenyltin (TPhT) in the sediment and water of seven harbor were collected and analyzed. 179 literatures and reports about these three toxic chemicals, sponsored by research institutes and governmental institutes in the past ten years in Taiwan, were collected and reviewed.
