摘要
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,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;各点位检出物浓度较低,绝大部分化合物远低于国标;但检出种类多,均受到不同程度的有机污染,而地下水污染相对较轻。
Using multi-analysis techniques including GC/MS,HPLC,GC/ECD,this thesis determine and study the organic pollutants of 23 drinking sources in Henan.The period time of sampling is made three times in spring, summer and winter. The result shows that 740 kinds of organic compounds are searched and selected,among them 261 kinds of compounds are the main toxic and harmful pollutants according the toxicity documents. PAHs and phathlates are the common pollutants and their situations are very serious, many of them have been characterized as carcinogens, mutagens and teratogens. The concentration levels of most poison compounds are far lower than the new drinking source water's standards of the Nation. But every points are polluted in different degree,and groundwater are relatively slightly contaminated.
