摘要
综述了近年来水环境中PAHs源解析的方法,包括化学质量平衡法、因子分析法、稳定碳同位素法和比值法等,重点评述了方法的理论基础、适用条件、应用状况和存在问题,并结合我国情况分析了水环境中PAHs源解析方法的发展趋势。认为因子分析法与多元统计方法结合使用是当前我国PAHs源解析的最适用方法,可以实现对源贡献率的定量分析,与GIS技术结合应用,能实现PAHs源的空间统计分析,反映污染源影响作用的空间分布规律。
The methods used for source apportionment of polycyclic aromatic hydrocarbons in aquatic environment were introduced, including chemical mass balance, factor analysis （FA） stable isotope, ratio method and so on. The emphasis on theoretical principle, applicable condition, application and problems of the methods were summarized. The development of PAHs source apportionment method was analyzed with Chinese aquatic environment. The method of FA and multivariate statistical analysis combined with FA was widely used in practical operation, especially by the means of combination with GIS. FA was able to provide a practically effect on PAHs source resolution, with statistical analysis of the space pattern of PAHs source.
