采用气相色谱与质谱联用(GC/MS)技术,在一个航次内对南黄海表层沉积物中16种优先监控的PAHs的污染状况进行了调查,采用菲/蒽、荧蒽/芘、荧蒽/(荧蒽+芘)、吲哚芘/(吲哚芘+苯并(g,h,i)苝)等特定比值对PAHs来源进行了分析.结果表明,南黄海表层沉积物中检出PAHs的总含量为90.4～732.65ng·g-1,各站点均以4～6环为主;与其它站位相比,倾废区的H01站位受到PAHs污染较为明显,无论是16种PAHs总量还是高分子量组分最高值都出现在该站点,虽然该海区沉积物中PAHs的含量没有超出生物影响低值,但苯并(b)荧蒽、吲哚芘和苯并(g,h,i)芘等一些没有最低安全标准的PAHs也有不同程度的检出,对海洋生物具有潜在的毒副作用.PAHs可能来源于原油、生物和煤燃烧造成的污染. The gas chromatography-mass spectrometry (GC / MS) technique was used to investigate the pollution status of 16 preferentially monitored PAHs in the surface sediments of the South Yellow Sea within a single voyage. Phenanthrene, anthracene, fluoranthene, / (Fluoranthene + pyrene), indole pyrene / (indolpyrene + benzo (g, h, i) perylene) were used to analyze the origin of PAHs.The results showed that PAHs were detected in surface sediments of the South Yellow Sea The total content of PAHs was 90.4-732.65ng · g-1, and all stations were mainly 4 ~ 6 rings. Compared with other stations, PAHs pollution was more obvious in H01 station of dumping area, no matter the total amount of 16 kinds of PAHs Or high molecular weight components all appeared at this site. Although the content of PAHs in the sediments of the sea area did not exceed the low bio-impact value, the benzo (b) fluoranthene, indolpyrene and benzo (g, h, i ) Pyrene and some other non-minimum safety standards of PAHs are also detected to varying degrees, has potential side effects on marine organisms.PAHs may be derived from crude oil, biomass and coal pollution caused by combustion.
