The article offers information about a study that explores mercury contaminations in watersheds of the western U.S. which is often associated with the employment mercury in natural enrichment, historic mining, and ore processing. In this study, the proponents applied controlled manipulations of four replicated experimental wetland designs with different water and soil mercury concentrations to determine the potential impacts on methyl mercury export. Results showed that wetting and drying were found to exacerbate methyl mercury export and changes in the system hydraulic residence time did not affect methyl mercury export. Furthermore, sulfate and nitrate additions did not significantly affect methyl mercury export, most likely due to the concentrations applied. |
