Monitoring system for environmental ECD sensitive substances by means of capillary ECD gas chromatography (ECD-GC) was developed and applied to blue mussels as a model biological indicator. Thirty-three blue mussel taken from Osaka North Port, Osaka Misaki-cho and Hokkaido Funkawan Bay were analyzed. In addition, samples from Funkawan Bay were acclimated in the three different seawaters of Osaka North Port, Chiba and Yokohama and analyzed. Peak heights and retention times of capillary ECD-GC sensitive substances were recorded on the disk of personal computer. After retention times were transferred to retention indices for organochlorine compounds, detected components were quantified by using DDE as a standard. Common components were selected from the detected substances in order to prepare new data-file for pattern analyses. Calculation of similarity factors and cluster analysis were carried out on the patterns and the total concentrations of the common components. From these analyses, the differences and the changes of both quality and quantity of pollutants were clearly observed. The results showed that the developed system would be applicable to a repid monitoring method for environmental pollutants.
