| 摘 要： | 本文应用沉积物质量评价基准法对九龙江口及邻近港湾红树林区表层沉积物中多环芳烃的污染现状进行了生态风险评价,并定量分析了多环芳烃的相对污染强度.研究结果表明:各测站区多环芳烃相对污染系数均小于1,范围为0.022~0.620,污染程度尚属较低,引起生物毒性效应的几率相对较小.低分子量多环芳烃芴、萘和二氢苊占总相对污染系数比例较高(平均分别为18.1%、16.7%和15.3%),因而具有相对较高的潜在生态危害风险. |

| Abstract: | Based on Sediment Quality Assessment Guidelines,the status and ecological risk of PAHs pollution in surface sediment of mangrove areas in Jiulongjiang Estuary and neighboring harbors was assessed.With quantitative analysis of PAHs' relative contamination factor(RCF),it was concluded that RCFs of PAHs in all sampling areas were ranging from 0.022 to 0.620,all less than 1.It suggested that the PAHs concentration in mangrove areas in Jiulongjiang Estuary and neighboring harbors was at relatively lower level,indicating a lower incidence of adverse biological effects.Low molecular weight PAHs such as fluorene,acenaphthene and naphthalene contributed higher percentage of RCF than the other PAHs,with average contributions of 18.1%,16.7% and 15.3%,respectively.The results suggested a relatively higher potential ecological risk from low molecular weight PAHs. |
