通过综合文献综述对水生系统中汞污染的来源进行了研究。结果表明，水生系统中汞污染最重要的人为来源是：(1) 大气沉降，(2) 侵蚀，(3) 城市排放，(4) 农业材料，(5) 采矿，以及(6) 燃烧和工业排放。加盖和疏浚是水生系统中汞污染的两种可能的补救方法，而自然衰减是一种被动净化替代方法。对于受汞污染的水生系统，封盖似乎是一种经济且有效的补救方法。疏浚是一种昂贵的补救方法。然而，对于污染严重的系统，疏浚可能更有效。自然衰减几乎不需要成本，对于污染较少的场地来说是一种可能且非常经济的选择。适当的风险评估对于评估补救和被动净化方法的有效性及其潜在的不利环境影响是必要的。建模工具在水生系统汞污染的修复和被动净化方面有着光明的前景。对现有的汞迁移和转化模型进行了审查和比较。
Sources of mercury contamination in aquatic systems were studied in a comprehensive literature review. The results show that the most important anthropogenic sources of mercury pollution in aquatic systems are: (1) atmospheric deposition, (2) erosion, (3) urban discharges, (4) agricultural materials, (5) mining, and (6) combustion and industrial discharges. Capping and dredging are two possible remedial approaches to mercury contamination in aquatic systems, and natural attenuation is a passive decontamination alternative. Capping seems to be an economical and effective remedial approach to mercury-contaminated aquatic systems. Dredging is an expensive remedial approach. However, for heavily polluted systems, dredging may be more effective. Natural attenuation, involving little or no cost, is a possible and very economical choice for less contaminated sites. Proper risk assessment is necessary to evaluate the effectiveness of remedial and passive decontamination methods as well as their potential adverse environmental effects. Modeling tools have a bright future in the remediation and passive decontamination of mercury contamination in aquatic systems. Existing mercury transport and transformation models were reviewed and compared.
