淮南市平山头水源地水中PAEs污染情况分析

Study on Phthalates Pollution of in the Water Samples of the Drinking Water Source of Pingshantou Water Plant in Huainan City

以淮南市平山头水厂水源4种邻苯二甲酸酯类(PAEs):邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸丁基苄基酯(BBP)、邻苯二甲酸二丁酯(DBP)为研究对象,研究了水源地水中PAEs的污染情况。研究结果表明:DMP、DEP、BBP、DBP的检出率分别为50%、83.3%、83.3%、100%,DBP的达标率为100%;DMP、DEP、BBP、DBP对∑4PAEs污染的贡献率依次为:5.2%、3.7%、20.1%、71.1%,说明平山头水厂水源地水中PAEs污染主要以DBP为主。水源地各采样点∑4PAEs的含量范围0.632～1.623μg/L,其采样断面平均浓度顺序为:上游>中游>下游。

The paper selected four kinds of PAEs （DMP, DEP, BBP, DBP） in the drinking water source of Pingshantou Water Plant in Huainan as the study object to get the pollution ststus of PAEs in the drinking water sources. The results are as follows： The detection rate of DMP, DEP, BBP, DBP in water are respectively 50%, 83.3%, 83.3%, 100%. Standard-reaching rateof DBP is 100%; The average contribution rates of DMP, DEP, BBP, DBP for ∑ 4PAEs in water are in order： 5.2%, 3.7%, 20.1%, 71.1%. It shows that PAEs in the drinking water source of Pingshantou Water Plant is dominated by DBP. The range of the concentration of ∑ 4PAEs about the sampling points in drinking water source is 0.632-1.623μg/L, and the order of average concentration about sampling section is following： Upper reaches〉 Middle reaches〉 Downstream.
