Arsenic toxicity: A South Asian perspective Arsenic is likely the most talked about metalloid in the modern world because of its toxic effects on both animal and plants. Further arsenic pollution is now producing negative impacts on food security especially in many south Asian countries. Since plants are a major food source their adaptation to As rich environments is essential as is being informed about recent findings on multifarious aspects of the mechanisms of arsenic toxicity and tolerance in plants. Although numerous research works and review articles have been published in journals annual reviews and as book chapters to date there has been no comprehensive book on this topic. This book contains 19 informative chapters on arsenic chemistry plant uptake toxicity and tolerance mechanisms as well as approaches to mitigation. Readers will be introduced to the latest findings on plant responses to arsenic toxicity various tolerance mechanisms and remediation techniques. As such the book offers a timely and valuable resource for a broad audience including plant scientists soil scientists environmental scientists agronomists botanists and molecular biologists
