摘　　要：采用萃取-高效液相色谱法对鞍山城区9个水样中的5种邻苯二甲酸酯类化合物(PAEs)[邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二辛酯(DOP)和邻苯二甲酸二(2-乙基己基)酯(DEHP)]进行了定量分析。结果表明,除DEP外,其余4种PAEs均检出,最高检出量为18.186 3 mg/L(DOP),最低检出量为0.044 6 mg/L(DBP),含量超过国家标准,说明鞍山城区环境水已受到PAEs的污染。对测定结果进行了分析,说明PAEs的含量和分布特征与地区工业化程度和人员活动密集程度有关。PAEs已对鞍山地区环境造成了威胁,应引起重视并采取手段解决问题。Five phthalate acid esters（PAEs）（dimethyl phthalate（DMP）,diethyl phthalate（DEP）,di-n-butyl phthalate（DBP）,dioctyl phthalate（DOP）,di（2-ethylhexyl） phthalate（DEHP）） in water samples in Anshan city have been determined by a high performance liquid chromatography and extraction.Except DEP,the remaining four PAEs have been detected in water samples with the maximal detection 18.186 3 mg/L（DOP） and the minimal detection 0.044 6 mg/L（DBP）,which have already exceeded the national standard.The results showed that the environmental water has been polluted in Anshan city.According to the analysis of the result,the concentrations and distribution characteristics of PAEs have relationship with district industrialization and personnel activities and intensity.PAEs are threatening the environment of Anshan city.Attention should be paid to relevant departments and measure should be adopted to solve the problems.
