Full Description
Cadmium Contamination in Soils and Plants: Mechanisms and Mitigation focuses on the processes and mechanisms of transformation and transport of cadmium (Cd) in soil-plant systems, covering aspects from inputs and outputs of Cd to/from soil-plant systems, biogeochemical transformation of Cd in soil, uptake and transport of Cd in plants, toxicity and detoxification of Cd in microorganisms and plants, dietary intake of Cd and impact on human health, risk assessment and bioremediation technologies to mitigate Cd contamination. Contamination of soil with Cd, a highly toxic heavy metal, is a global problem due to both geogenic reasons and anthropogenic activities. Cd is readily taken up by plants, causing toxicities to plants and posing a significant risk to human health via dietary exposure. There has been much scientific progress in understanding various aspects of the topic, especially the mechanisms and mitigation technologies. This book to synthesizes and presents a comprehensive look at the state-of-the-art knowledge of Cd in soil-plant systems. Cadmium Contamination in Soils and Plants serves as a key authoritative resource for researchers, graduate students, environmental protection professionals and policy makers who are interested in the issues of soil contamination, agricultural sustainability, food safety and public health, and environmental protection and remediation.
