摘　　要：目的监测某塑料拆解地区水环境中邻苯二甲酸二（2-乙基己基）酯（DEHP）的污染水平及探讨其可能的来源,为保护当地环境、促进居民健康提供基础数据。方法用固相萃取和气相色谱联用技术检测河水、井水、塘水、无组织排放水和饮用水中DEHP水平。结果各类水样中均检出DEHP,检出率为100%。河流污染断面DEHP平均浓度2.05μg/L,为清洁断面平均浓度（0.32μg/L）的6.4倍。暴露区井水（14.20μg/L）和塘水（135.68μg/L）DEHP的平均浓度分别为对照组井水（0.79μg/L）和塘水（0.37μg/L）的18和367倍。暴露区无组织排放水样中DE-HP的检出范围在0.36~161.86μg/L。结论塑料拆解地区井水、塘水和无组织排放水样中均检出DEHP,且DEHP的平均浓度均超过中国《生活饮用水卫生标准》（GB5479-2006）和《地表水环境质量标准》（GB3838-2002）的要求,应引起重视。Objective To study levels of di （2-ethylhexyl） phthalate （DEHP） in the water samples from an plastics reclaim site for environment protection and residents＇ health. Methods The levels of di（2-ethylhexyl） phthalate（DEHP） of water samples collected from the river, wells, ponds, tap water, and industrial effluent in the exposure region and the control region were detected with solid-phase extraction and gas chromatography method. Results The DEHP levels in all water samples were determined. The average DEHP level in the fiver water samples from the polluted section （2. 05 μg/L） was 6.4 folds higher than that of the control section （0.32 μg/L）. Average DEHP level in the pond （ 135.68 μg/L） and the well （14.20 μg/L） water samples from the exposure region were 18 folds and 215 folds higher compared with those （0.79 p.g/L and 0.37 μg/L） in the control region,respectively. The DEHP level in industrial effluent sample ranged from 0.36 μg/L to 161.86 μg/L. Conclusion Attention should be paid to DEHP levels in well, pond water and the industrial effluent because they exceed the national standards.
