Although adverse health effects of heavy metals have been known for a long time, exposure to heavy metals continues and is even increasing in some areas. Remediating heavy metal contaminated soils and water is necessary to reduce the associated health and ecological risks, make the land resource available for agricultural production, enhance food security, and scale down land tenure problems. This book discusses the causes and the environmental impact of heavy metal contamination. It then explores many exciting new methods of analysis and decontamination currently studied and applied in the field today.

UN studies show that high-income, developed nations treat about 70 percent of their wastewater. However, in low-income developing nations, only 8 percent of wastewater undergoes any kind of treatment. Inadequate water treatment has serious consequences for both human health and the environment. The articles in this compendium provide a representative cross sample of both developing and developed nations' water treatment facilities. Included are the following topics: Reclaimed water for irrigation reuse in developing countries Sludge-handling practices in Micronesia The removal of phthalate esters from Chinese water sources Disposal of domestic wastewater in Nigeria Ameba-enrichment in a South African water treatment plant Bioenergy from wastewater produced by a Brazilian meat-processing plant The presence of various pharmaceutical contaminants in the River Thames Wastewater recycling in Greece The impact on surface water from contaminants released from German water treatment plants A Canadian constructed wetland's effectiveness for the removal of various contaminants from wastewater Accessing irrigation from treated wastewater in the United States The spacial distribution of fecal indicator bacteria in the groundwater beneath two American water treatment plants Detection of contamination from retinoid acid reception agonists in Japanese water treatment plants The editor, a respected international expert in the field, has selected investigations that offer essential information for ongoing research at the graduate and professional levels, as well as for environmental engineers and others responsible for choosing the most efficient water treatment technologies.

Assessment, Restoration and Reclamation of Mining Influenced Soils covers processes operating in the environment as a result of mining activity, including the whole spectra of negative effects of anthropopressure and the environment, from changes in soil chemistry, changes in soil physical properties, geomechanical disturbances, and mine water discharges. Mining activity and its waste are an environmental concern. Knowledge of the fate of potentially harmful elements and their effect on plants and the food chain, and ultimately on human health, is still being understood. Therefore, there is a need for better knowledge on the origin, distribution, and management of mine waste on a global level. This book provides information on hazard assessment and remediation of the disturbed environment, including stabilization of contaminated soils and phytoremediation, and will help scientists and public authorities formulate answers to the daily challenges related to the restoration of contaminated land. Provides a thorough overview of the processes operating on mining-devastated areas, as well as origin, distribution, and deactivation of harmful elements Includes outcomes and recommendations of the Global Mining Initiative that are widely regarded as the code of conduct in the minerals industry Contains global case studies that elucidate various aspects of assessment and restoration of mine-contaminated land

The objective of this hugely important text is to contribute to the existing knowledge on soil pollution and remediation. Stress is given to the critical assessment of the used analyses and methods for study effects in combined chemical pollution (organic pollutants and pesticides, metals) on soil biota and fertility. Also featured is, among other things, an evaluation of specific aspects of risk assessment, and an assessment of advanced technologies for soil remediation.

The CRC Concise Encyclopedia of Nanotechnology sets the standard against which all other references of this nature are measured. As such, it is a major resource for both skilled professionals and novices to nanotechnology. The book examines the design, application, and utilization of devices, techniques, and technologies critical to research at the atomic, molecular, and macromolecular levels ranging from 1 to 100 nanometers. More than three dozen specific topics are examined, including nanomaterials, nanocatalysts, nanoceramics, nanocrystals, carbon nanotubes, drug delivery, nanopolymers, nanoparticles, nanocoatings, and nanomedicine. The material is presented in a concise manner and has been updated to reflect the latest applications and research findings. Entries are organized alphabetically, making information easy to find. While coverage is comprehensive, each topic is presented concisely with a wealth of illustrative material and an accompanying eBook providing full-color figures and images.

Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children’s neurological development; to recommend a prevention strategy for protecting children’s health and development.
