| Outline of Final Research Achievements |
The toxic chemicals that have been regulated in the Japanese PRTR/MSDS act were conducted literature searches, photo-degradation test and hydrolytic degradation test. The degradation products of 249 kinds from the 92 kinds parent chemicals were listed up. The simultaneous measuring method for the 60 kinds parent chemicals and their 106 kinds child chemicals were developed by using a solid phaze extraction and GC/MS or LC/MS/MS analysis. The environmental monitoring was conducted in urban rivers and 70 kinds child chemicals were detedcted, while 50 kinds parent chemicals detedted at the same time. The child chemicals of 46 kinds persisted at the concentration over 0.1ug/L. There was a child chemical with stronger toxicity than its parent chemical. Necessity for evaluation of toxicity of degradation products and increase of environmental risks were shown in this study.
