摘要 于2019年6月对雄安新区和保定市周边地区地表水和地下水进行采样,分析水环境中7种对羟基苯甲酸酯(parabens)组分的含量水平及生态风险.结果表明:对羟基苯甲酸甲酯(MeP)和对羟基苯甲酸丙酯(PrP)的检出率为100%;地表水中的主要组分为MeP,占比达93.4%,地下水中的主要组分为MeP,对羟基苯甲酸乙酯(EtP)和PrP,三者占比达98.0%;地下水中parabens的含量水平高于地表水;地表水中parabens的浓度呈白洋淀下游高于上游的空间分布特征,而地下水中的parabens总量在安新县境内较高,平均浓度可达10.1ng/L;总体而言,当前雄安新区水环境中parabens的污染程度较低、生态风险较小.本文可为未来雄安新区建设中的水环境管理提供污染水平参比值和决策依据,也可为雄安新区水环境中其它药品和个人护理品(PPCPs)的污染研究提供参考. Surface water(SW)and groundwater(GW)samples were taken from Xiong’an New Area and the vicinity of Baoding in June 2019.Concentrations of seven parabens were determined for these samples and the associated ecological risk was assessed.The detection rates of MeP and PrP were 100%.MeP was found to be the predominant compound in SW samples,with a mass contribution of 93.4%,and MeP,EtP and PrP were the predominant compounds in GW samples,with a total mass contribution of 98.0%.The GW samples overall had a higher content of parabens than the SW samples.In space,the SW samples downstream Baiyang Lake showed higher concentrations of parabens than those upstream of Baiyang Lake,while GW samples taken from Anxin County had relatively high concentrations of parabens(10.1ng/L on average).Overall,the water pollution level of parabens,as well as the associated ecological risk,was relatively low in the study area.This study offered reference values for water quality management in the future development of Xiong’an New Area,and sheds light on studies of other PPCPs in the same area.
