Sulfur and iron influence the transformation and accumulation of mercury and methylmercury in the soil-rice system

摘要

Much attention is directed to the accumulation of mercury and methylmercury (MeHg) in rice grown on Hg-contaminated paddy fields, since they pose a risk to the health of both people and wildlife. Ultimately, measures to control the accumulation of Hg and MeHg in rice should become a key focus of research on this topic. The objective of this study is to test whether Hg and MeHg accumulation are reduced in polished rice when iron and sulfur are added together to the paddy fields during the cultivation of rice.
