摘要: PAHs的生物富集性使其在养殖海域的研究对人体健康和生态环境具有重要意义。流沙湾海水PAHs污染的特征是2-3环的化合物为主要污染物,总体浓度水平较低,但变化大;内湾PAHs含量较外湾高,与各站点所在位置,水体交换以及污染源有关;由菲/蒽和荧蒽/芘7、种化合物的线性相关性,以及主因子成份分析得出流沙湾PAHs的污染源主要为石油源和燃料燃烧等混合源。Abstract: Owing to the bioconcentration of PAHs,study of PAHs in mariculture area is significant on human health and ecological environment.The characteristics of PAHs in Liusha Bay were that the main pollutants were 2-3 ring PAHs,and their concentrations were relatively low but fluctuating greatly.The concentrations of PAHs in sites were related to the locations,and hydrodynamics and their sources.According to the phenanthrene/anthracene and fluoranthene/pyrene ratios, the linear correlation and principal component analysis,the sources of PAHs in Liusha Bay were oil and combustion.
