| 摘 要： | 为了解太湖重点区域水环境中邻苯二甲酸酯(phthalate esters,PAEs)的污染情况,对丰水期、枯水期和平水期目标区域的水体和沉积物中6种PAEs进行分析,3个水期水体中PAEs浓度分别为1.6~11.2μg·L-1(平均值3.68μg·L-1)、nd~6.21μg·L-1(平均值1.3μg·L-1)和nd~1.72μg·L-1(平均值0.48μg·L-1),从上游至下游未呈现明显浓度变化,其中邻苯二甲酸二(2-乙基己基)酯di(2-ethylhexyl)phthalate,DEHP]对ΣPAEs浓度的贡献比较大,邻苯二甲酸二正丁酯(di-n-butyl phthalate,DBP)在某些采样点高于国内标准.沉积物中PAEs含量范围在0.74~6.90μg·g-1(平均值2.64μg·g-1),主要成分是DBP和DEHP.生态风险评价的结果表明,DBP和DEHP是重点区域中最主要的风险因子;沉积物PAEs中所有种类的含量均未超过风险评价低值(effect range low,ERL),对生物的潜在危害较小.与国内外河流、湖泊与河口等沉积物中PAEs污染水平比较,太湖重点区域水环境中PAEs污染属于中等水平.工业污染和城市活动是水环境中邻苯二甲酸酯的主要来源.
