巢湖表层沉积物中多环芳烃分布特征及来源
摘要
于2010年,采用野外采样调查、色谱分析与统计比较的方法,研究巢湖表层沉积物中27个采样点中多环芳烃(PAHs)分布特征及污染来源.结果表明:巢湖表层沉积物中检测出的14种优控PAHs总浓度为116.0～2832.2 ng/g(DW),平均值为898.9±791.0 ng/g(DW).多环芳烃组成主要以5～6环PAHs为主,占总量的32%～58%.沉积物中总有机碳含量与PAHs总量呈现良好相关性.利用蒽/(蒽+菲)与苯并[a]蒽/(苯并[a]蒽+屈)比值法对PAHs来源进行解析得出,巢湖表层沉积物中PAHs主要来源为燃烧源.与国内其它水体PAHs含量对比表明,巢湖沉积物中PAHs污染处于中等水平.生态风险评估得出南淝河表层沉积物中PAHs存在生态风险,其它采样点表层沉积物中PAHs生态风险均较低.
To clarify polycyclic aromatic hydrocarbons(PAHs) contamination characteristics in Lake Chaohu,27 surface sediment samples from different locations in the lake were collected in 2010.Concentrations of 14 kinds of PAHs measured by HPLC were identified as priority pollutants by the US EPA.The total concentration of PAHs ranged from 116.0 to 2832.2 ng/g dry weight,with an average value of 898.9±791.0 ng/g dry weight.The profiles of PAHs showed that 5-and 6-ring PAHs were predominant,which accounted for 32%-58% of the total,respectively.A good correlation between TOC content and the total PAHs concentration was observed.Based on Anthracene/(Anthracene+Phenanthrene) and Benzo(a)anthracene/(Benzo(a)anthracene+Chrysene) ratios,PAHs originated largely from the high-temperature pyrolytic process.Risk assessment indicated that the sediment in Nanfei River was most likely to pose biological impairment,while low toxicological risk of PAHs was found in other sampling sites.
