骆马湖表层沉积物中多环芳烃的源解析

摘要

运用主因子分析和多元线性回归分析法对骆马湖表层沉积物中16种优控多环芳烃(PAHs)的来源进行源解析,探讨几种主要燃烧源PAHs的贡献率.结果表明,沉积物中PAHs主要来源于煤炭和秸秆燃烧以及交通工具尾气排放,累计贡献率为99.7％.%16 polycyclic aromatic hydrocarbons(PAHs) in the surface sediment of Luoma Lake are quantitatively determined by high performance liquid chromatography. Different source contributions of PAHs in surface sediments of Luoma Lake are also calculated hy principal factor analysis and multiple linear regression. The result shows that the cumulative contribution rate of coal, straw combustion and traffic emission is completely 99. 7%.
