The polycyclic aromatic hydrocarbons (PAHs) in water and sediment from the Pearl River around Guangzhou Higher Education Mega Center are analyzed by GC - MS. The results show that the Pearl River around Guangzhou Higher Education Mega Center is obviously contaminated by PAHs. The concentrations of prior PAHs in water and sediment are in the range from 1061.7 to 6577.8ng/L and 896.1 to 7248ng/g respectively. The PAHs mainly derive from the leakage of petroleum product and the combustion of fossil fuel.%利用GC-MS对广州大学城珠江水域的地表水及表层沉积物中多环芳烃(PAHs)的含量进行了分析.结果表明,广州大学城珠江水域及表层沉积物中均可检出PAHs,水体优控PAHs总量在1061.7～6577.8ng/L之间,沉积物中优控PAHs总量分布在896.1～7248ng/g之间.广州大学城珠江水域的PAHs属混合来源,主要有石油类产品的输入(漏油泄油)和化石燃料的燃烧(大气沉降).
