Arsenic & Rice [Paperback]

Rice is the staple food for half of the worlds population. Consumption of rice is the major exposure route globally to the class one, non-threshold carcinogen inorganic arsenic. This book explains the sources of arsenic to paddy soils and the biogeochemical processes and plant physiological attributes of paddy soil-rice ecosystems that lead to high concentrations of arsenic in rice grain. It presents the global pattern of arsenic concentration and speciation in rice, discusses human exposures to inorganic arsenic from rice and the resulting health risks. It also highlights particular populations that have the highest rice consumptions, which include Southern and South East Asians, weaning babies, gluten intolerance sufferers and those consuming rice milk. The book also presents the information of arsenic concentration and speciation in other major crops and outlines approaches for lowering arsenic in rice grain and in the human diet through agronomic management.This book examines the global pattern of arsenic concentration and speciation in rice, discusses human exposures to inorganic arsenic and the resulting health risks. It outlines approaches for lowering arsenic in the human diet through agronomic management.Acknowledgements.- Abbreviations;
