浙闽沿岸泥质区南部表层沉积物中多环芳烃的分布、来源及生态风险评价
|
摘要
为探明浙闽沿岸泥质区南部表层沉积物的多环芳烃(PAHs)污染状况,测定了浙闽沿岸泥质区南部的32个表层沉积物样品中多环芳烃的含量,探讨了浙闽沿岸泥质区多环芳烃的分布、来源及生态风险。结果表明,浙闽沿岸泥质区南部表层沉积物PAHs总浓度介于(12.95~156.05)×10-9,相对于其他区域属于较低水平。特征分子比值法和SPSS分析结果均表明本研究区域中PAHs主要来源于煤炭、石油的燃烧,并有部分石油源。生态风险评价结果表明浙闽沿岸泥质区南部表层沉积物PAHs存在一定程度的生态风险,应当多加留意并采取相关措施进行防护。
In order to investigate the polycyclic aromatic hydrocarbons(PAHs) contamination of the surficial sediment in the south Coastal Mud Area off Zhejiang-Fujian(CMAZF),the content of polycyclic aromatic hydrocarbons in the surficial sediments were analyzed,and the distribution,sources and ecological threats of polycyclic aromatic hydrocarbons were also discussed. The results showed that the total PAHs concentrations of the surficial sediment in the south CMAZF ranged from 12. 95 × 10-9 to 156. 05 × 10-9. The results of isomeric ratio method and SPSS analysis indicated that PAHs in the study area mainly come from the combustion of coal and oil,and partly from oil source. The assessment results concerning with ecological risk evaluation of PAHs revealed that,to some extent,there might exist ecological risk in the surficial sediment of south CMAZF,and more attention should be paid to protect the marine environment.
