This book presents state-of-the-art knowledge related to concerns about methylmercury (MeHg) in the soil-rice system. It covers increasing concerns about 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 demethylated 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, this book will be an important resource for anyone interested in Hg contamination in soils and rice and the related risk for human and environmental health.
