以渤海湾海域及黄河口外海域为研究区,采用GC/MS检测手段对两海域表层海水中多环芳烃组分进行定性和定量分析,并分析其主要组成、分布、来源及输入方式,从而对多环芳烃污染状况进行初步评价。定量分析的结果表明,渤海湾海域17种多环芳烃含量为82.6~181.8 ng/L,黄河口外海域为43.7~122.4 ng/L。与国内外其他海域海水或沉积物相比,研究区多环芳烃的污染属于中等水平;通过对研究区域表层海水中芳烃组成特征的分析得出,多环芳烃主要来自化石燃料的燃烧,其中黄河口外远岸海域多环芳烃以石油来源为主,兼有燃烧来源。两海域均为近岸以燃油排放为主,远岸以燃煤排放为主。
Taking the areas of Bohai Bay and the Yellow River Estuary as study area, the components of PAHs in the surface waters of the two seas were qualitatively and quantitatively analyzed by GC / MS, and the main components, distribution, sources and input methods were analyzed. Polycyclic aromatic hydrocarbons pollution preliminary evaluation. The results of quantitative analysis showed that the content of 17 PAHs in Bohai Bay was 82.6 ~ 181.8 ng / L and that of the Yellow River Estuary was 43.7 ~ 122.4 ng / L. Compared with the seawater or sediment in other sea areas at home and abroad, the pollution of PAHs in the study area belongs to medium level. By analyzing the characteristics of aromatic hydrocarbon in the surface seawater, PAHs mainly come from the combustion of fossil fuels, Polycyclic aromatic hydrocarbons (PAHs) in the estuarine offshore area are dominated by petroleum sources and contain both combustion sources. Both of the two areas are near-shore with fuel-based emissions and far-shore with coal-fired emissions.
