This book provides an overview to researchers, graduate, and undergraduate students, as well as academicians who are interested in arsenic. It covers human health risks and established cases of human ailments and sheds light on prospective control measures, both biological and physico-chemical. Arsenic (As) is a widely distributed element in the environment having no known useful physiological function in plants or animals. Historically, this metalloid has been known to be used widely as a poison. Effects of arsenic have come to light in the past few decades due to its increasing contamination in several parts of world, with the worst situation being in Bangladesh and West Bengal, India. The worrying issue is the ingestion of arsenic through water and food and associated health risks due to its carcinogenic and neurotoxic nature. The impact of the problem is widespread, and it has led to extensive research on finding both the causes and solutions. These attempts have allowed us to understand the various probable causes of arsenic contamination in the environment, and at the same time, have provided a number of possible solutions. It is reported that more than 200 mineral species contain As. Generally, As binds with iron and sulfur to form arsenopyrite. According to one estimate from the World Health Organization (WHO), contextual levels of As in soil ranges from 1 to 40 mg kg-1. Arsenic toxicity is related to its oxidation state which is present in the medium. As is a protoplastic toxin, due to its consequence on sulphydryl group it interferes in cell enzymes, cell respiration and in mitosis. Exposure of As may occur to humans via several industries, such as refining or smelting of metal ores, microelectronics, wood preservation, battery manufacturing, and also to those who work in power plants that burn arsenic-rich coal.

Arsenic-contaminated groundwater is considered one of the world’s largest environmental health crises, as more than 300 million people in more than one-third of countries worldwide are at risk of groundwater arsenic poisoning. This book addresses how arsenic in groundwater impacts human health by using the frameworks of natural sciences, social sciences, and health sciences in the context set by environmental and legal considerations. Arsenic in Groundwater: Poisoning and Risk Assessment examines the spatial, quantitative, and qualitative aspects on arsenic poisoning; for instance, using geographical information systems (GIS) to investigate the spatial discontinuity of arsenic-laced water in spatial and temporal dimensions to uncover patterns of variations over scales from meters to kilometers. Spatial risk mapping provides insight for academics, researchers, policy makers, and politicians on possible long-term strategies for arsenic mitigation. Qualitative methodological approaches uncover the hidden issues of arsenic poisoning on human health and the related social implications. The book also examines legal aspects, such as the right to safe drinking water, as well as an in-depth look at how community participation can shape public policy. Features: Describes arsenic poisoning from both the scientific and social science perspectives Includes technical insights drawn from GIS-based modeling for spatial arsenic discontinuity and spatial health risks of arsenic poisoning Provides a state-of-the-art review of the human health literature and cutting-edge scientific evidence for arsenic-related health and social implications Examines the environmental justice and legal issues of drinking water and its quality Presents environmental policy and public mitigation strategies with Public Participation GIS (PPGIS) related to arsenic contamination More than 2,000 references serve as valuable resources for various aspects of arsenic poisoning

This book is open access under a CC BY 4.0 license. By 2050, human population is expected to reach 9.7 billion. The demand for increased food production needs to be met from ever reducing resources of land, water and other environmental constraints. Rice remains the staple food source for a majority of the global populations, but especially in Asia where ninety percent of rice is grown and consumed. Climate change continues to impose abiotic and biotic stresses that curtail rice quality and yields. Researchers have been challenged to provide innovative solutions to maintain, or even increase, rice production. Amongst them, the ‘green super rice’ breeding strategy has been successful for leading the development and release of multiple abiotic and biotic stress tolerant rice varieties. Recent advances in plant molecular biology and biotechnologies have led to the identification of stress responsive genes and signaling pathways, which open up new paradigms to augment rice productivity. Accordingly, transcription factors, protein kinases and enzymes for generating protective metabolites and proteins all contribute to an intricate network of events that guard and maintain cellular integrity. In addition, various quantitative trait loci associated with elevated stress tolerance have been cloned, resulting in the detection of novel genes for biotic and abiotic stress resistance. Mechanistic understanding of the genetic basis of traits, such as N and P use, is allowing rice researchers to engineer nutrient-efficient rice varieties, which would result in higher yields with lower inputs. Likewise, the research in micronutrients biosynthesis opens doors to genetic engineering of metabolic pathways to enhance micronutrients production. With third generation sequencing techniques on the horizon, exciting progress can be expected to vastly improve molecular markers for gene-trait associations forecast with increasing accuracy. This book emphasizes on the areas of rice science that attempt to overcome the foremost limitations in rice production. Our intention is to highlight research advances in the fields of physiology, molecular breeding and genetics, with a special focus on increasing productivity, improving biotic and abiotic stress tolerance and nutritional quality of rice.
