| 摘 要： | 为了解"引江济太"过程中塑化剂类污染物对贡湖的输入特征,于2013年8月对14个采样点的7种邻苯二甲酸酯类化合物(PAEs)的浓度进行采样分析,并通过美国环保署(USEPA)推荐的方法,对其环境风险进行评价.结果表明:各采样点邻苯二甲酸二丁酯(DBP)和邻苯二甲酸二环己酯(DCHP)均有检出,除采样点10、11和12外,邻苯二甲酸二乙酯(DEP)也有检出,其余4种均未检出,长江引水经望虞河进入贡湖后,DEP、DBP和DCHP浓度均有不同程度的降低,且其最高浓度均出现在望虞河长江引水处(采样点1),说明在引水过程中长江水对望虞河有明显的PAEs输入,而贡湖锡东水厂DEP浓度高于贡湖其他采样点,南泉水厂DBP和DCHP浓度高于贡湖其他采样点,金墅湾水厂PAEs浓度总体处于较低水平.环境健康风险评价结果显示:DEP的最大非致癌风险值为3.91×10-8a~(-1),未超过国际组织规定范围,而DBP的最大非致癌风险值为1.17×10-5a~(-1),超过英国皇家协会RS规定的1×10-6a~(-1),但均对人体无明显非致癌危害.

| Abstract: | Concentrations of seven phthalic acid esters (PAEs) in surface water samples collected from 14 sites along the Wangyu River and the Gonghu Bay (Lake Taihu) were analyzed to clarify the pollution characteristics of plasticizers during the period of "Water Transfers on Lake Taihu from the Yangtze River" in August 2013. In addition, environmental health risk assessment was also conducted by the method recommended by United States Environmental Protection Agency (USEPA). The results showed that dibutyl phthalate (DBP) and di-cyclohexyl phthalate (DCHP) were detected at all sites. Diethyl phthalate (DEP) were also detected at all but sites 10, 11 and 12. Concentrations of DEP, DBP, and DCHP in the Wangyu River were higher than those in the Gonghu Bay, and were the highest at site 1 in the Wangyu River which was originated from the Yangtze River. Concentrations of DEP in Xidong water plant and DBP and DCHP in Nanquan water plant were the highest in the Gonghu Bay, while concentrations of PAEs in Jinshuwan water plant were the lowest. The results of environmental health risk assessment showed that maximum non-carcinogenic risk of DEP was 3.91×10-8 a-1, lower than values recommended by USEPA, Royal Society (RS) and International Commission on Radiation Protection (ICRP). The maximum non-carcinogenic risk of DBP was 1.17×10-5 a-1, higher than that of 1×10-6 a-1 recommended by RS. It however would not lead to obvious non-carcinogenic harm to human bodies. |
