  13. The goal of the research project is to clarify the occurrence and behavior of hazardous substances in East-Asia seas by measuring organotin and organohalogen compounds in seawater, sediments and mussels. The main purpose of this year is to develop analytical and sampling methods for these compounds.

  13. The aim of this study is to investigate the influence of synthetic biodegradable polymers and their degraded products on the natural environment. Mechanism of biodegradation in various environments, survey of microbes, identification and their accumulation of degraded products, their acute toxicity to living things containg microbes and cells, fate of metals used for production of polymers are studied. From consideration of these results, the complete safety of novel synthetic biodegradable polymers and plastics would be verified.
