| 摘 要： | 以NP(nonylphenol,壬基酚)、4-t-OP(4-t-octylphenol,辛基酚)和BPA(bisphenol A,双酚A)为目标物质,研究酚类EDCs(内分泌干扰物)在太湖流域宜溧河地表水体和悬浮物中的空间分布特征及风险评价.结果表明,太湖流域宜溧河地表水体中ρ(NP)、ρ(4-t-OP)和ρ(BPA)分别为156.2 ～434.0、11.8～19.4和89.8 ～353.8 ng/L,悬浮物中w(NP)、w(4-t-OP)和w(BPA)分别为520.0～9 818.2、52.0 ～454.5和39.0 ～2 454.5 ng/g.流域内生活及工业污水排放可能是宜溧河流域水体中酚类EDCs的主要来源,ρ(NP)与ρ(NO3-)呈显著正相关(R=0.860,P＜0.01).宜溧河水系中酚类EDCs在水相-悬浮物相的有机碳标准分配系数为4.14 ～6.41,表明悬浮颗粒物的吸附是水体中EDCs迁移的一个重要途径.研究区域中NP、4-t-OP和BPA的入湖量分别为506、57.9和297 kg/a.风险评价结果表明,该地区部分河段ρ(EDCs)具有潜在的生态风险. |
