摘要:Monitoring system for environmental pollutants (ECD-sensitive substances in blue mussels) was developed by means of capillary gas chromatography. System-flow and the algorism of the software were summarized as follows. Peak heights and retention times of ECD sensitive substances in blue mussels were integrated and were transferred from GC to personal computer by the on-line system. Retention times were transferred to retention indices and detected components were quantified by using DDE as a standard. Common components were selected from detected substances, and data-files were prepared for statistical analyses. Pattern analyses of these components in blue mussels were carried out by means of the calculation of similarity factors and cluster analysis. From these analyses the differences and the changes of the quality and the quantity of pollutants in blue mussels are clarified. Continuous monitoring and accumulation of data are planned for the standarization of the pollution patterns of various seas. Long-term tendency of the environmental pollution would be recognized by the comparative analyses of standarized patterns and a later monitoring result.
