Abstract

<p>Semi-volatile industrial chemicals of 147 kinds were investigated their degradability by the screening tests for photolysis/hydrolysis. The numbers of chemicals with degradation ratio of 80% or higher were 0 in hexane in the dark, 89 in hexane in the bright, 6 in water in the dark and 55 in the water in the bright, and almost all of the degradation was photolysis. As the results of the literature surveys of major information sources deeply related with the chemicals management in Japan, 84 chemicals were degradable and 32 chemicals were non-degradable among 300 industrial chemicals. This result indicated that the public information concerning degradability of chemicals in the environment was not known so much. A list of 55 industrial chemicals and their 105 degradation products were made up, the simultaneous measuring methods using GC-MS and LC-MS/MS were established, and then the simultaneous measuring were carried out for 138 river water samples collected from 73 points. Not only the chemicals discharged to environment were detected but also their degradation products at the various molar concentration ratios. Therefore, the comprehensive environmental monitoring including degradation products were considered urgent issue as well as the collection of their hazard information.</p>
