This book presents state-of-the-art knowledge related to concerns on methylmercury (Hg) in the soil-rice system. It covers increasing concerns of human exposure to methylmercury through the consumption of Hg-contaminated rice and shows the global contamination of soil, and how Hg can be mobilized, immobilized, methylated, and de-methylated in soils. The authors present the biogeochemical process through which rice plants accumulate Hg. This book comprehensively displays the biogeochemical behavior of Hg in paddy soils and rice plants, as well as the current remediation technologies to mitigate Hg risks from paddy soil ecosystems.Features Provides cutting-edge knowledge on mercury in paddy field ecosystems. Discusses the key biogeochemical transformation processes of mercury in soil. Explains the accumulation processes of mercury in rice plants. Includes case studies on how to inhibit mercury accumulation in rice plants. Shows the application of Hg stable isotope traces in paddy soil-rice field studies. Intended for researchers, graduate students, and professionals working in fields such as Geochemistry, Agronomy, and Environmental Science and Engineering, interested in Hg contamination in soils, rice and the related risk for human and environmental health.

This book presents an intensive study on the biogeochemical cycle of mercury in a river-reservoir system in Wujiang River Basin, the upper branch of the Yangtze River.
