Leizhou coastal marine area, Liusha Bay and Shenzhen Bay represented open coastal area and half-closed bay, respectively. This study discussed the differences of PAHs concentration levels, spatial distribution and sources in sediments from these three marine areas. The results showed that detected ratios of 15 PAHs were 100%, and major compounds were 3-ring and 4-ring PAHs, especialy Phe, Fla, Pry and Bbf; Sigma PAHs concentration was Leizhou < Shenzhen < Liusha. In spatial distribution, PAHs concentrations were the east < the south < the west in Leizhou; the inside > the outside, and the aquaculture > the non-aquaculture in Liusha Bay and Shenzhen Bay. It suggested that large-scale mariculture inside bay played an important role in PAHs pollution and might make it serious. Oil, fossil fuels and biomass burning were the dominant sources of PAHs in sediments from Leizhou coastal area, Liusha Bay and Shenzhen Bay.
雷州近岸海域、流沙湾和深圳湾分别代表开阔近岸海域和半封闭海湾。本研究探讨了这三个海域沉积物中多环芳烃（PAHs）的浓度水平、空间分布及来源差异。结果表明，15种PAHs的检出率均为100%，主要化合物为三环和四环PAHs，尤其是菲、荧蒽、芘和苯并[b]荧蒽；ΣPAHs浓度为雷州＜深圳＜流沙。在空间分布上，雷州PAHs浓度为东部＜南部＜西部；流沙湾和深圳湾则为湾内＞湾外，养殖区＞非养殖区。这表明湾内大规模海水养殖对PAHs污染起到了重要作用，可能使其污染加重。石油、化石燃料和生物质燃烧是雷州近岸海域、流沙湾和深圳湾沉积物中PAHs的主要来源。
