河南省城市水源水微量有机污染现状调查研究

为探查和研究与公众生命健康关系密切的饮用水有机污染现状,笔者运用GC MS等多种有机分析技术对河南省主要城市的23个水源水中的有机物进行了分析研究。结果表明:共检出740种有机物,初步筛选出261种有毒污染物;多环芳烃类和酞酸酯的污染非常突出;各点位检出物质量浓度较低,绝大部分化合物远低于国家标准,但检出种类多;地表水均受到不同程度的有机污染,而地下水污染相对较轻。 

Study on Trace Organic Pollution of Water Sources of Cities in Henan Province

In order to investigate the current status of organic pollution of drinking water closely related to public health,multiple analysis techniques,including GC/MS,etc.,were applied to analyze the organic pollutants in 23 water sources in Henan Province.The results showed that 740 kinds of organic compounds were detected,among which 261 were screened initially as toxic pollutants.The pollution of PAHs and phathlates was very outstanding.The concentration levels of detected pollutants at various sites are low,with those of most compounds far lower than the national standards.But the varieties of detected pollutants were numerous and all the sites were polluted by organic compounds in different degrees.Also,the groundwater was relatively less contaminated.
