| Abstract: |
| Mercury is one of the most toxic heavy metal pollutants, and in natural environments it occurs in three forms：zero-valent mercury（Hg0）, inorganic divalent mercury（Hg2+ and its complexes）, and alkyl mercury（methyl mercury, ethyl mercury, and their complexes）. Among these, the organic forms are more toxic to organisms and have attracted greater attention. Therefore, it is important to study and analyze these various forms of mercury in aquatic environments. Here, current research into the presence of various forms of mercury in surface water, groundwater, and sewage locally and abroad were reviewed and their concentration ranges were summarized. Additionally, common analysis methods of different chemical forms of mercury were reviewed. We summarized commonly used mercury detection methods, including their pretreatment procedures, detection limits, and linearity ranges and discussed their merits and demerits as well as their applicability. Finally, the development challenges of these detection methods and future trends of researching total, inorganic, and alkyl mercury were revealed. |
