Abstract:
Objective To analyze the main sources of dioxins pollution in fishes samples. Methods The principal components analysis was employed to identify different dioxin emission sources data and to analyze the environmental and aquatic samples. The Principal Component Analysis seems to be a powerful tool for source identification with the ratio of each concentration of the 2,3,7,8-subtituted congener to the concentration of the total 2,3,7,8-subtituted congeners. Results The result obtained from Principal Component Analysis showed that there were different dioxin compositions between chemical emission sources and other emission sources. Conclusion The pollution sources of PCDD and PCDF polluted aquatic life from different countries,regions are not the same.
