Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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, Asbinds with iron and sulfur to form arsenopyrite. According to one estimate from the World Health Organization (WHO), contextual levels of Asin soil ranges from 1 to 40 mgkg-1. Arsenic toxicity is related to its oxidation state which is present in the medium.Asis 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.

Hardcover. Zustand: new. Hardcover. The manufacturing of recyclable products and an efficient recovery of resources such as chemicals, materials, and energy from waste streams are the key enablers of the circular economy. This book highlights the efficient management of waste into resources through the introduction of advanced technology able to convert waste into a secondary resource. It describes different technologies and urban mining tools used to recover materials from different types of waste. It also emphasizes that natural materials are limited though demand for the materials continues to increase, and how that demand can be sustainably fulfilled by secondary resources materials that come from urban mining.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book focuses on the mechanistic (microscopic) understanding of radionuclide uptake by plants in contaminated soils and potential use of phytoremediation. The key features concern radionuclide toxicity in plants, how the radioactive materials are absorbed by plants, and how the plants cope with the toxic responses. The respective chapters examine soil classification, natural plant selection, speciation of actinides, kinetic modeling, and case studies on cesium uptake after radiation accidents.Radionuclide contaminants pose serious problems for biological systems, due to their chemical toxicity and radiological effects. The processes by which radionuclides can be incorporated into vegetation can either originate from activity interception by external plant surfaces (either directly from the atmosphere or from resuspended material), or through uptake of radionuclides via the root system. Subsequent transfer of toxic elements to the human food chain is a concrete danger. Therefore, the molecular mechanisms and genetic basis of transport into and within plants needs to be understood for two reasons: The effectiveness of radionuclide uptake into crop plants - so-called transfer coefficient - is a prerequisite for the calculation of dose due to the food path. On the other hand, efficient radionuclide transfer into plants can be made use of for decontamination of land - so-called phytoremediation, the direct use of living, green plants for in situ removal of pollutants from the environment or to reduce their concentrations to harmless levels.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Phytoremediation is an emerging technology that employs higher plants for the clean-up of contaminated environments. Basic and applied research have unequivocally demonstrated that selected plant species possess the genetic potential to accumulate, degrade, metabolize and immobilize a wide range of contaminants.The main focus of this volume is on the recent advances of technologies using green plants for remediation of various metals and metalloids. Topics include biomonitoring of heavy metal pollution, amendments of higher uptake of toxic metals, transport of heavy metals in plants, and toxicity mechanisms. Further chapters discuss agro-technological methods for minimizing pollution while improving soil quality, transgenic approaches to heavy metal remediation and present protocols for metal remediation via in vitro root cultures.

Hardcover. Zustand: new. Hardcover. This book provides a comprehensive review on how radionuclides occur in the environment; how radionuclides are distributed in soil; how the migration of radionuclides in plants occurs; and their consequences on human health. It explains how the speciation of radionuclide interferes in the uptake and accumulation processes in fruits, and includes case studies as well as reviews of modern and state-of-the-art technology related to radioactive material uptake in plants.This volume is a useful reference to researchers in the field of radionuclide contamination in foods and will also be helpful for graduate and undergraduate students specializing in radioactive waste disposal and its toxicity effects in food products and their consequences on humans. Shipping may be from our Sydney, NSW warehouse or from our UK or US warehouse, depending on stock availability.

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.
