| 摘 要： | 研究了葫芦岛市区不同污染源的三条河流水体及沉积物中汞的分布特征,探讨了氯碱厂、锌冶炼厂及非点源污染引起的河流汞污染特征的差异。研究表明曾经接受过氯碱厂废水污染的五里河,表层沉积物中汞浓度为0.03700~16.07 mg.kg-1,平均值9.241 mg.kg-1;河水中总汞浓度为0.08400~10.45μg.L-1,平均值为1.530μg.L-1,水中汞源于河流沉积物溶出。受锌冶炼厂废水污染的茨山河,表层沉积物中汞浓度为0.3440~132.5 mg.kg-1,平均值52.45 mg.kg-1;水中总汞浓度为0.05800~11.04μg.L-1,平均值为2.377μg.L-1,水中汞源于锌冶炼厂直接排放。无典型点源污染的连山河总汞源于面源污染,表层沉积物中汞浓度为0.2150~19.55 mg.kg-1,平均值5.126 mg.kg-1;降水冲刷带入河流造成的总汞浓度为0.3200~17.32μg.L-1,平均值为4.642μg.L-1。 |

| Abstract: | In this paper the distribution characteristics of mercury in water and sediments of three rivers which flow through the urban area of Huludao City have been thoroughly studied.The three rivers have different mercury pollution sources including zinc smelting,color-alkali and non-point source pollution respectively and differences in mercury pollution characteristics between them have been discussed.The study has shown that the total Hg concentrations in the surface sediments of the Wuli River are within the ... |
