本文研究了辽宁省二道坊河河道沉积物中汞的存在形态特征及其影响因素，结果表明；汞各形态百分含量的顺序为：王水溶汞＞硝酸溶汞＞盐酸溶汞＞水溶性汞＞碱溶性汞，并且随深度的增加呈现出规律性变化；汞的每一形态受沉积物性质的影响程度存在较大的差异，充分揭示了汞各种形态富集的特征，为该河流的汞污染的综合防治提供了重要的科学依据。
In this paper, the morphological characteristics and influencing factors of mercury in the sediments of Erdaofang River in Liaoning Province were studied. The results showed that the order of the percentages of mercury species was as follows: aqua regia mercury> mercuric nitrate> mercuric chloride> water solubility Mercury> alkali-soluble mercury, and showed a regular change with the increase of depth. Each shape of mercury was greatly affected by the nature of sediment, which fully revealed the characteristics of various forms of mercury enrichment. The comprehensive prevention and control of mercury pollution provides an important scientific basis.
