| 摘 要： | 用主成分分析和多元线性回归分析方法研究了天津3个不同空间区域表土中PAHs的来源及其相对贡献.结果表明:燃煤和炼焦是各区最重要的PAHs释放源.塘沽汉沽高值区尤其如此,其燃煤和炼焦二者合计占总排放贡献的79%,交通源仅占21%.市中心及近郊区交通来源上升到与燃煤来源相当的水平(约各占35%),此外,焚烧产生的PAHs也占很高比例(21%).农村低值区则呈现出更多多源特点;秸秆燃烧是本区独有的,约占总贡献的11%.根据源解析得到的结果与根据燃料用量和排放因子计算的排放结果有一定可比性. |

| Abstract: | The sources of PAHs in the topsoil were apportioned using principal component analysis with multiple linear regression.Three sub-regions with significant differences in PAH levels and profiles were investigated individually.The results indicated that coal combustion and coking production were the dominate PAH source for the entire Tianjin,particularly for Tanggu-Hangu region with the highest PAH level,to which 79% of PAHs came from coal combustion and coking industry and 21% was from vehicles.For the city center and outskirts,vehicles and coal burning contributed 35% each,while incineration provided 21% of the total. Sources of PAHs in rural soil with relatively low level of PAHs were more diverse.In addition to coal,vehicles,and coking,straw burning added 11% to the total.The results based on the source apportionment were compared with those from emission modeling. |
