This edited book brings together a diverse group of environmental science, sustainability, and health researchers to address the challenges posed by global mass poisoning caused by chromium contamination of soil and plants. In recent years, contamination of the environment by chromium has become a major concern. Chromium is a non-degradable, harmful, and toxic pollutant which negatively affects the environment. It is unique among the heavy metals found in industrial wastewater and sewage and sludge, as it may exist as a trivalent cation and as anion in the hexavalent state in the pH range of agricultural soils. It is used on a large scale in many different industries, including metallurgy, electroplating, production of paints and pigments, tanning, wood preservation, chemical production, and pulp and paper production. These industries are contributing larger amount of chromium, which can ultimately have significant adverse effects on biological and ecological activities of ecosystem. Chromium enters the food chain through consumption of plant material. A high concentration of chromium has been found to be harmful to vegetation. As the chromium concentration in plants increases, it adversely affects several biological parameters and eventually renders the soil barren. The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches and case studies from different parts of the world. This book is a valuable resource to students, academicians, researchers, and environmental professionals who are doing field work on chromium contamination throughout the world.

The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect. With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered. Features Explores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of: 1,4-Dioxane (mature in its emerging contaminant life cycle) Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant) Hexavalent chromium (former emerging contaminant with evolving science) 1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle) Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.

Inorganic Contaminants and Radionuclides is a single reference covering common inorganic contaminants in detail, including their distribution in the environment, challenges linked to management, geogenic sources, anthropogenic sources, exposure and effects, international agreements and legislation relating to the contaminant, remediation options and global case studies. In addition, the book provides summaries of contaminated sites and key details about contaminants to present a more comprehensive understanding and improve remediation and management practices. The book's clear, consistent organization makes it a valuable resource for researchers, students and practitioners working in environmental science, environmental management and environmental engineering.One of the major constraints to assessing and remediating contaminated sites is the lack of awareness of the extent and severity of contaminated sites amongst the community, regulators, policymakers, industry operators, university graduates and environmental managers. This book helps to manage these constraints. - Provides a one-stop reference on the nature and properties of inorganic contaminants, including a transdisciplinary approach to managing contaminated sites - Includes global case studies covering contaminated site assessment, management and remediation - Presents in-depth research and data on specific contaminants, with a separate chapter for each contaminant
