摘要
阐述了常用的受体模型化学质量平衡模型(CMB),正定矩阵因子分解模型(PMF)、因子分析/多元线型回归(FA/MLR)、绝对因子得分/多元线性回归(AFS/MLR)、非负约束的因子分析模型(FA-NNC)和同位素来源解析技术(CSRA)的方法和原理,总结了受体模型应用于三种典型持久性有毒物质(PTS)PAHs,PCDD/Fs和PCBs的来源解析研究进展,并对PTS类污染物来源解析的发展趋势和我国源解析研究亟待解决的问题进行展望.
Quantitative and qualitative source apportionment methods on persistent toxic substances (PTS)were reviewed in this study. The theories and techniques of the most popular receptor models, such as chemical mass balance (CMB), positive matrix factorization (PMF), factor analysis/multiple linear regression (FA/MLR), absolute factor score/multiple linear regression (AFS/MLR), factor analysis with non-negative constraints(FA-NNC) and compound-specific radiocarbon analysis, were elucidated. In addition, some recent advances on source apportionment of typical PTS ( PAHs, PCDD/Fs and PCBs) were summarized. Finally, a brief summary and prospect for the development trend of source apportionment of PTS were put forward.
