| 摘 要： | 利用液液萃取法和气相色谱-质谱方法对佛山境内高明河水环境多环芳烃（PAHs）进行了测定,并对PAHs的分布特征与通量进行了初步研究.结果表明高明河水环境中16种优控PAHs的浓度范围在41.6～375.6 ng/l之间,从上游到下游总体呈递增的趋势,其下游浓度偏高可能与荷城街道较为密集的工业和人口分布有关.高明河水环境PAHs的总含量高于欧美一些低污染水域,但低于国内一些主要河流.高明河PAHs年通量约为333.8 kg.

| Abstract: | PAHs in surface water collected from the Gaoming River were measured by liquid - liquid extraction combined with gas chromatography - mass spectrometry（ GC - MS） method. The distribution characteristics and annual flux of PAHs were inves- tigated. The concentrations of PAHs were 41.6 - 375.6 ng/1 and showed increasing trend from the upstream to the downstream. The high concentration of PAHs in the downstream may be related to the dense distribution of industrial and population of Hecheng Street. Total PAHs concentrations in Gaoming River were relatively higher than European and American water areas and lower than the main water areas in China. The annual flux of total PAHs was 333.8 kg. |
