【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。

【Abstract】 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 river 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 μg/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.
