摘    要:对王快水库沉积物中16种多环芳烃含量进行了检测,结果表明,王快水库沉积物多环芳烃含量处于中等污染水平.多环芳烃总含量由库区上游到坝前逐渐升高,多环芳烃总含量在沉积物纵向上的总体分布趋势是随着剖面深度的增加而降低,低环的萘和菲,高环的荧蒽、苯并b]荧蒽、屈和芘是沉积物中主要的优势化合物,表层和剖面沉积物中多环芳烃的含量与有机碳含量呈正相关关系,相关系数分别为0.8154和0.9534.王快水库沉积物中多环芳烃主要来源化石燃料及生物质的燃烧,风险评价结果表明,严重的多环芳烃生态风险在王快水库沉积物中不存在,但是芴化合物含量超过了风险评价低值,可能存在着对生物的潜在危害.

关 键 词:多环芳烃  王快水库  沉积物  分布  生态风险

Abstract:16 polycyclic aromatic hydrocarbons (PAHs) of sediments were measured in Wangkuai Reservoir, Hebei Province. The results showed that the sediments of Wangkuai Reservoir appear to be moderate pollution by PAHs. PAH pollutions became more serious from reservoir upstream to front of the dam. The total PAHs concentrations decrease with the depth of sediment. Nap, Phe, Fla, BbF, Chr, and Pyr were dominant in sediments. The total PAHs concentration was directly proportional to the content of TOC with a correlatio...
Keywords:Polycyclic aromatic hydrocarbons  Wangkuai Reservoir  sediment  distribution  ecological risk
