| 摘 要： | 对黑潴河下游表层沉积物中16种多环芳烃(PAHs)的污染现状进行了调查研究。结果表明,表层沉积物中PAHs总量变化范围为41.2～129.3ng/g(平均值为83.7ng/g),PAHs的组成以5～6环PAHs组分为主。黑潴河下游沉积物中PAHs主要来源于周边地区化石燃料的高温燃烧。比较了基于不同方法建立的沉积物中PAHs环境基准值的差异,分析产生差异的原因,选择生态效应区间法对黑潴河沉积物中的PAHs进行了生态风险评价。黑潴河下游PAHs生态风险较小,属PAHs低生态风险河道。

| Abstract: | The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) in surface sediments along the downstream of Heizhu River were investigated. The results showed that the total PAHs concentrations in surface sediment ranged from 41.2 to 129.3 ng/g (average value was 83.7 ng/g). The PAHs with 5~6 rings were dominant in the sediments. Source analysis showed that PAHs in the sediments were derived from the combustion of fossil fuels under high temperature. Various sediment quality criteria based on different methods were systematically compared and the causes of difference were analyzed. The ecological risk of PAHs in the sediments was evaluated by using biological effects database approach. The results showed that the ecosystem risk of PAHs in the sediments of Heizhu River was relatively low. |
