1、武汉市汉江及长江水源饮用水中有机物污染谱系研究摘要:[目的]了解武汉市长江和汉江为水源的末梢水中有机物的污染谱系,为汉江和长江水体污染监测与治理,以及其饮用水有机物污染危险性评价提供资料和依据。[方法]于丰水期和枯水期分别采集武汉市汉江和长江为水源的末梢水水样,用XAD-2和XAD-8等比例混合树脂(XAD-2/8)富集水样中的有机污染物,用GC/MS方法分析各样品的有机物组成。[结果]在本实验条件下,以汉江为水源的末梢水,在丰水期和枯水期分别检测出有机物110种和102种。以长江为水源的末梢水,在丰水期和枯水期分别检测出有机物79
2、种和95种。污染物中以烷烃、烯烃、卤代烃、酯类、邻苯二甲酸酯类为主。汉江水源末梢水有机物种类无论是在枯水期还是丰水期均明显多于长江水源的末梢水。[结论]武汉市以汉江和长江为水源的末梢水受到一定程度的有机物污染,污染物种类复杂且来源广泛,应引起人们的高度重视。关键词:大孔吸附树脂;饮用水;有机污染物;气质联用;优先控制物中图分类号:R123.1文献标志码:A���
