The main mercury contamination include: industry and the waste residue from refine zinc furnace and so on. But refine zinc furnace let gaseous mercury to atmosphere, which can remote transportation along with airflow and enter into hydrophily-zoology through dry and humid sedimentation, so refine zinc furnace is liked to picking up mercury pollution in Caohai.
流域周围存在大量土法炼锌活动,而不同矿石在冶炼过程中向大气排放气态单质汞,单质汞可以随大气环流进行长距离输送并通过干湿沉降进入水生生态系统,因此,土法炼锌可能加剧草海汞污染。
