地表水环境中PAHs源解析的方法比较及其应用?

In this study, source apportionment of PAHs in surface water has been studied to control and eliminate water pollution. Until now, source identification, is considered as the method of quality analysis, only can ensure the type of the main sources of pollutants. The other one, source apportionment, can quantitative the contribution of various sources. Comparing variable methods of source apportionment of PAHs, we has analysed and discussed the principle, characteristic and scope of the application of two methods that are usually divided into qualitative analysis and quantitative analysis. The applications and results of the distribution and source apportionment of PAHs in surface water and sediments were contrasted and analyzed based on this comparison, respectively. Then, the source of contaminations was also analyzed briefly. The results of the source apportionment indicated that PAHs in aqueous environment and sediments in inland region mainly came from the process of combustion, such as burning of coal, wood, and other minerals. PAHs in coastal areas which contain aqueous and sedimental environments are derived from petroleum and other combustion processes. Subsequently, the influence of burning of petroleum in coastal areas was more obviously than that in inland region.
