The authors have developed an analytical method for determining trace amounts of 285 kinds of chemicals in natural waters by GC-ion trap MS. The results of overall recovery tests at <TEX>$0.1{\mu}g/l$</TEX> showed that the mean recovery was 92.1% and the mean relative standard deviation was 10.8%. The mean of the method detection limits was <TEX>$0.036{\mu}g/l$</TEX>. From the results of analysis of real samples, it was confirmed that this method is useful to elucidate the concentration levels and the fate of chemicals in the aquatic environment.
