Book Description
This contributed volume covers a comprehensive account of the sources, toxic biological as well as environmental impacts, and possible remediation strategies for contamination by heavy metals. In biological systems, toxic metals affect the integrity of cellular organelles and act as carcinogens causing chromosomal aberrations or as systemic toxicants leading to cardiovascular, neurobehavioral, and immunological disorders. In plants, they interfere with photosynthesis, fertility, metabolite, and chlorophyll synthesis. Toxicity induced by heavy metals involves mechanistic approaches that need to be understood properly. They cannot be degraded by biological or chemical means and thus can only be converted to less harmful forms. The conventional detection methods include biosensors, voltammetry, atomic absorption spectrometry, and inductively coupled plasma with atomic emission spectrometry. All such strategies for metal detection and mitigation strategies are covered in this title under one section. This book incorporates classical views along with modern scientific approaches to develop an understanding of the subject matter suitable for academicians, researchers, planners, policymakers, NGOs, and environmental consultancies and raise awareness on this concern. Topics representing diverse sections namely environmental impacts, biological effects, and methods used for detection and remediation have been included to address all possible contemporary issues on the topic in one concise volume.

Book Description
Heavy Metals in the Environment: Impact, Assessment, and Remediation synthesizes both fundamental concepts of heavy metal pollutants and state-of-the-art techniques and technologies for assessment and remediation. The book discusses the sources, origin and health risk assessment of heavy metals as well as the application of GIS, remote sensing and multivariate techniques in the assessment of heavy metals. The various contamination indices like contamination factor, geoaccumulation index, enrichment factor, and pollution index ecological risk index are also included to provide further context on the state of heavy metals in the environment. Covering a variety of approaches, techniques, and scenarios, this book is a key resource for environmental scientists and policymakers working to address environmental pollutants. Covers state-of-the-art techniques for the assessment and remediation of heavy metals Presents the interdisciplinary impacts of heavy metals, including human health, ecosystems and water quality Includes various contamination indices, such as contamination factor, geoaccumulation index, enrichment factor, pollution index and ecological risk index

Book Description
Highlighted in this compilation of papers is the role and importance of heavy metals in the environment. It provides up-to-date information in a field of active research and progress, where the focus is on effects and interactions between the environment and organisms, as well as contaminant dynamics. Several papers address the impact of heavy metals on our health. The influence of metals on plants is described in an exhaustive study on lichens, which have been widely used as biomonitors for environmental contamination by heavy metals. Metals are also accumulated by animals, as seen in a chapter which focusses on sediment/benthic organism interactions and biomonitoring in fish. Soil interactions are discussed, as well as regional studies of freshwater sediments and the marine environment. The final part of the book addresses a crucial problem: the management of stabilized municipal waste sludges. As a result, the most important and significant recent trends are included, emphasizing interactions with and impacts of heavy metals on humans, animals, plants and soils.

Book Description
Following a description of the various sources and factors influencing the contents of heavy metal pollution in post-catastrophic and agricultural soils, subsequent chapters examine soil enzymes and eggs as bio-monitors, lead adsorption, the effects of arsenic on microbial diversity, and the effects of Mediterranean grasslands on abandoned mines. A third section focuses on the adaptation strategies used by plants and bacteria, such as Pinus sylvestris in industrial areas, and the rhizosphere in contaminated tropical soils and soil treated with sewage sludge. Further topics addressed include strategies of bioremediation, e.g. using transgenic plants as tools for soil remediation. This new volume on heavy metals in soil will be of interest to researchers and scholars in microbial and plant biotechnology, agriculture, the environmental sciences and soil ecology.

Book Description
It is often said that the “dosage” of any substance determines its remedy or poison effect. Heavy metal sources encompass sewage, pesticides, fertilizers, environmental contamination, occupational exposure/contact through inhalation, ingestion, and skin. Before the advent of technology/the industrial revolution, communicable diseases ravaged the human race but this seems to have given way to non-communicable diseases such as cancers, renal failure, hormonal distortion enzymes, inhibition of fetal growth, and DNA damage causing negative health issues due to heavy metals. This book brings to the fore probably the most recent experimental research/review on heavy metal contamination, remediating techniques, cellular tissue damage, and toxicological and antioxidant effects of heavy metals. It is hoped that its contents will make interesting reading for all.

Book Description
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.

Book Description
This book is concerned with heavy metals, which are considered to be the most hazardous pollutants present in the water system. Heavy metals are extensively studied and their effects on human health are reviewed here. Although several adverse health effects of heavy metals are known for a long time, exposure to heavy metals continues and is even increasing in some parts of the world. This books deals with the source of heavy metals in the environment and possible mitigation measures for metal recovery. The technology available for the detection of heavy metals and the latest remediation techniques are also discussed in detail. In this way, the book also addresses general background to polymers and their composite materials for removal of specific toxic heavy metals from waste water. The different adsorption isotherm models and adsorption mechanism using biosorption methods are also described. The widespread applications of low-value agricultural products, ion-exchange, coagulation, precipitation, flocculation, ultra-filtration and electrochemical methods are mentioned. The book reviews the essential issues and will be of interest to academicians, research scholars and industries. It will be the precious resource for all undergraduate and postgraduate students at institutes and universities.
