This book covers cadmium contamination of soil and plants, its sources, acute and long-term impacts on the environment and human health, and overall challenges posed by the global poisoning issue. Cadmium is among the elements that have been most broadly used by man over time, which has led to extensive pollution of surface soils, mainly associated with the mining and smelting of the metal and the addition of organic cadmium compounds to petrol. The release of cadmium into the atmosphere from various high-temperature processes has also led to surface contamination on a regional and even global scale. Cadmium is particularly firmly bound to humic matter in organic-rich soil and to iron oxides in mineral soil and is rather immobile in the soil unless present at very high concentrations. Plants grown on cadmium-rich soils incorporate cadmium, thus increasing the concentration of cadmium in crop plants. Cadmium thus enters the food chain through the consumption of plant material, whichposes important health risks to humans and animals. In this book, readers will find out about the latest mitigation strategies, including a multi-disciplinary approach to address cadmium contamination. Recent methods in cadmium detoxification, speciation, and molecular mechanisms are included, and the book offers the knowledge required for efficient risk assessment, prevention, and countermeasure. Divided into 3 parts, this book brings together expert contributions on cadmium toxicity. In the first part, readers will find out about the different sources and distribution of cadmium in soil and plant ecosystems. The second part of the book outlines the health risks linked to cadmium toxicity, and in the final part, readers will discover sustainable cadmium toxicity mitigation strategies and potential applications of recent biological technology in providing solutions. This book is a valuable resource for students, academics, researchers, and environmental professionalsdoing fieldwork on cadmium contamination throughout the world.

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.

This book presents mercury toxicity with respect to remediation and health issues. It covers sources of mercury contamination, its impact on human health, and prospective remediation by both bioremediation and phytoremediation with the application of recent advanced techniques such as genetic engineering and nanotechnology.Both anthropogenic activities and natural processes cause the release of mercury into different spheres of the environment resulting in severe adverse impacts. Increased anthropogenic discharge of mercury leads to disturbance in its natural biogeochemical cycle, which results in unenviable diseases and hazardous health effects. Mercury pollution is responsible for causing neurobehavioral, kidney, heart, gastrointestinal, liver, and other diseases. Many published works about the impact of mercury on health are also available worldwide; however, there is no complete understanding available on toxicological studies of mercury that covers the broader spectrum of findings ranging from sources of exposure to mercury toxicity to its remediation strategies.This book brings together a diverse group of environmental science, sustainability, and health researchers to address the challenges posed by global mass poisoning caused by mercury contamination. The book also proposes solutions to contamination through multi-disciplinary approaches.The book contains three sections. The first part describes the different sources and distribution of mercury in soil and plant ecosystems. The second part explains the health risks linked to mercury toxicity. The third part addresses sustainable mercury toxicity mitigation strategies and the potential applications of recent technology in providing solutions. This book is a valuable resource to students, academics, researchers, and environmental professionals working in the field of mercury contamination.
