松花江汞污染综合治理后环境现状调查

Investigation on present environmental condition of Songhua river mercury pollution after comprehensive treatment

摘要:
目的调查松花江流域汞污染综合治理后环境现状。
方法以松花江汞污染综合治理后吉林地区为调查组, 未受汞污染的长春郊区为对照组, 采用加氧燃烧-冷原子吸收法, 测定2组环境中的汞含量。
结果调查组环境汞含量与未受污染的对照组环境汞含量比较差异无统计学意义(P > 0.05);松花江流域环境汞含量与10年前比较差异有统计学意义(P < 0.01)。
结论随着主要工业汞与甲基汞污染源的治理和根治, 松花江流域环境汞污染已基本得到控制。

Abstract:
Objective To investigate the environmental condition of Songhua rivers mercury pollution after comprehensive eatment.
Methods The polluted region by mercury of Songhua River after comprehensive reatment of Jilin City was used as a survey group and unpolluted region by mercury of Changchun city as control group.To detect the mercury content of environment of the two groups by means of oxygen buring-cold atom absortpion.
Results The difference of the mercury content between the two groups had no statistical significance(P > 0.05).Compared with the environmental mercury content of Songhua River now and ten years ago the difference had statistical significance(P < 0.01).
Conclusion After the treatment of major mercury sources of industrial and methyl mercury, Songhua river mercury pollution is brought under control.
