Water Pollution And Remediation Heavy Metals

Pollution of waters by toxic metals is accelerating worldwide due to industrial and population growth, notably in countries having poor environmental laws, resulting in many diseases such as cancer. Classical remediation techniques are limited. This books reviews new, advanced or improved techniques for metal removal, such as hybrid treatments, nanotechnologies and unconventional adsorbents, e.g. metal-organic frameworks. Contaminants include rare earth elements, arsenic, lead, cadmium, chromium, copper and effluents from the electronic, textile, agricultural and pharmaceutical industries.

This book highlights the latest research on dissolved heavy metals in drinking water and their removal.

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.

In the context of climate change and fossil fuel pollution, solar energy appears as a cheap and sustainable fuel for many environmental applications, yet the efficiency of techniques has to be improved. This book reviews recent methods and applications of photocatalysis for the treatment of wastewater containing bacteria, heavy metals, organic pollutants, dyes and tannery effluents. Basics of water pollution, polluted river ecosystems and membranes are also detailed.

POLLUTANTS AND WATER MANAGEMENT Pollutants and Water Management: Resources, Strategies and Scarcity delivers a balanced and comprehensive look at recent trends in the management of polluted water resources. Covering the latest practical and theoretical aspects of polluted water management, the distinguished academics and authors emphasize indigenous practices of water resource management, the scarcity of clean water, and the future of the water system in the context of an increasing urbanization and globalization. The book details the management of contaminated water sites, including heavy metal contaminations in surface and subsurface water sources. It details a variety of industrial activities that typically pollute water, such as those involving crude oils and dyes. In its discussion of recent trends in abatement strategies, Pollutants and Water Management includes an exploration of the application of microorganisms, like bacteria, actinomycetes, fungi, and cyanobacteria, for the management of environmental contaminants. Readers will also discover a wide variety of other topics on the conservation of water sources including: The role of government and the public in the management of water resource pollution The causes of river system pollution and potential future scenarios in the abatement of river pollution Microbial degradation of organic pollutants in various water bodies The advancement in membrane technology used in water treatment processes Lead contamination in groundwater and recent trends in abatement strategies for it Highly polluting industries and their effects on surrounding water resources Perfect for graduate and postgraduate students and researchers whose focus is on recent trends in abatement strategies for pollutants and the application of microorganisms for the management of environmental contaminants, Pollutants and Water Management: Resources, Strategies and Scarcity also has a place in the libraries of environmentalists whose work involves the management and conservation of polluted sites.

This book provides in-depth coverage of environmental pollution sources, waste characteristics, control technologies, management strategies, facility innovations, process alternatives, costs, case histories, effluent standards, and future trends in waste treatment processes. It delineates methodologies, technologies, and the regional and global effects of important pollution control practices. It focuses on toxic heavy metals in the environment, various heavy metal decontamination technologies, brownfield restoration, and industrial, agricultural, and radioactive waste management. It discusses the importance of metals such as lead, chromium, cadmium, zinc, copper, nickel, iron, and mercury.

Metals in Water: Global Sources, Significance, and Treatment covers metal pollution in water, where they come from, their effects, and remediation processes. Sections overview heavy metals pollution, including their global health impacts and remediation measures. Geogenic and anthropogenic input of heavy metals in water are described, along with global case studies, step-by-step methods on remediation techniques, different detection sensors, and assessment practices of toxicity of heavy metals. The book focuses on recent research surrounding heavy metals' contamination in water resources and its impact across the globe. Chapters incorporate both theoretical and practical aspects and serve as baseline information for water resources studies. This book is useful for postgraduate students, teachers and researchers working in areas of water resources and pollution, hydrochemistry, environmental remediation and toxicology who are looking to understand the affects metals have on water, the environment and health, and also those looking for methods for remediation. Presents global case studies of sites contaminated by metals, effects on the environment, and successful remediation techniques Includes a whole section on remedial measures, with clear step-by-step "how to" guides Provides chapters covering detailed biogeochemical processes

Meet the challenge of contaminated soil with a range of sustainable tools The remediation of soils which have been polluted by trace metals is an increasingly significant environmental challenge in an industrialized global economy. The ongoing revolution in green technologies, however, has seen a range of sustainable methods emerge for remediating soils, water, and other aspects of the environment polluted by trace metals. By putting them into practice, environmental researchers and industrial professionals will be able to improve soil and groundwater quality and public health globally. Remediation of Heavy Metals offers a clear, accessible reference on these methods and their applications. It offers an overview of the major effects of heavy metal contamination and works through each of the methods or protocols available to remediate soil and minimize pollution at the source. Remediation of Heavy Metals readers will also find: Comparison of different absorption materials for heavy metal removal Detailed discussion of physical, chemical, and biological remediation methods Case studies demonstrating proper remediation Remediation of Heavy Metals provides key knowledge for environmental scientists, environmental toxicologists, and other researchers or industrial professionals working in soil remediation, as well as advanced graduate students in these areas.
