Interactions of Mercury and Selenium in River System correlation between Se and Hg in the dissolved phase in river water was not significant (. > 0.05; Fig. .). This result was likely affected by the enhanced Se content in the downstream area contributed by the Se-enriched groundwater (Zhang et al. .).

Interactions of Mercury and Selenium in Soil-Rice Systemory-controlled experiments (rather than in natural fields with more complex conditions because they vary both spatially and temporally), and were only focused on the detoxifying effect of Se on inorganic Hg (IHg) but not methylmercury (MeHg) (Afton and Caruso .; Mounicou et al. ., .; Shanker et al. .; Yathavakilla and Caruso .).

Health Risk Assessment for Human Exposure to Seleniumxists in human and animal selenoproteins as selenocysteine (Sec) and selenomethionine (SeMet) and is incorporated into the active sites of antioxidant selenoenzymes (glutathione peroxidase and thioredoxin reductase) (Steinbrenner and Sies .; Taylor et al. .).

Research BackgroundEconomic development in China has made remarkable achievements over the past 30 years since the reform and opening policy in 1978. However, the environment has paid a heavy ecological cost. Among a number of environmental issues that confront China, Chinese mercury (Hg) pollution is receiving particular attention worldwide.

Research Subject, Methods and SignificanceThis research was performed with the intent of systematically studying the form, spatial and temporal distributions and migration of mercury (Hg) versus selenium (Se) and associated interactions between the two elements in the important environmental media of the Wanshan Hg mine area (surface rivers and the soil-rice system).

Biogeochemical Cycles of Selenium in River SystemSelenium (Se) typically occurs in the supergene environment in the following four oxidation states: –II (selenide), 0 (elemental selenium), +IV (selenite), +VI (selenate), as well as in organic compounds (Se(org)) (Patterson et al. .).
