Scientists Reveal Methylation/Demethylation Processes of Hg in Rice Paddy in Hg Mining Area
The research group headed by Prof. FENG Xinbin at IGCAS reported the speciation, distribution, and primary source of Hg in rice paddy at two contrasting Hg mining sites (the artisanal Hg mining site and the abandoned Hg mining site). Moreover, the specific methylation/demethylation rate constants were qualified using enriched Hg isotope addition technique.

The researchers suggest that bioavailable Hg derived from new atmospheric deposition appears to be ... DETAILS...   MORE...
