摘要
研究了北京市北部、西部、西南部城市居民生活区土壤中多环芳烃 ( PAHs)的分布特征 ,并对土壤中多环芳烃的来源进行了分析。结果表明 ,车流量较多的路边土壤 PAHs含量很高 ;工业区周围的生活区域PAHs含量较高。城市道路土壤中 PAHs主要来自燃烧源 ,而工业区 PAHs则显示为燃烧源和石油源的混合污染。
The distribution of sixteen compounds of polycyclic aromatic hydrocarbons(PAHs) in surface soil of Beijing has been investigated by GC-MS. The soil PAHs concentrations range from less than (366.0) ng·g^(-1) to 27 825.0 ng·g^(-1). The most contaminated soil has been sampled in plants and roadside. Total organic carbon(TOC) plays major roles in the distribution of PAHs. PAHs in Beijing living area soil mainly come from pyrolytic origins, while PAHs in plants areas originate from a mixture of pyrolysis and petroleum origin.
