摘要：
The author attempted to estimate environmental polychlorinated biphenyl (PCB) pollution factors using principal-component analysis, cluster analysis, and 3 kinds of chemical mass balance models (CMB8, Mr-CMB, Fr-CMB), based on detailed pattern data obtained from comprehensive congener analysis of PCB. In the principal-component analysis and the cluster analysis, 4 kinds of kanechlors and combustion-caused samples were identified, and the congener patterns were characterized. Next, based on the results, the author calculated the contribution rate of each PCB pollution factor in various environmental samples with CMB8, Mr-CMB and Fr-CMB, and compared and evaluated the analysis results of CMB. As a result, the estimated contribution rates were almost the same, and the results indicated the characteristics of the target samples accurately.
