Mercury and Sulfur Redox Cycling Affect Methylmercury Levels in Rice Paddy Soils across a Contamination Gradient

Recently, the research group led by Prof. FENG Xinbin from the Institute of Geochemistry, Chinese Academy of Sciences (CAS) has successfully traced Hg transformation processes in paddy soil, including methylation, demethylation, oxidation, and reduction, by using a multi-compound-specific isotope labeling technique (200HgII, Me198Hg, and 202Hg0). Responses of Hg transformation to sulfur input (sulfate and thiosulfate) were also elucidated. DETAILS... MORE...
