Environmental Heavy Metal Pollution and Effects on Child Mental Development


Book Description

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.




Heavy Metals


Book Description

Heavy metal pollution due to various sources such as from agro chemicals, ballast water, electronic waste, vehicle exhaust, industrial effluents, coal power plants, sludge wastes, medicinal chemicals, laboratory waste and domestic wastes are become a major threat to the environment. WHO has found there is a health risk due to long-range transboundary air pollutants containing heavy metals. Arsenic, Beryllium, radium, chromium and cadmium are well known carcinogens. Some of them(As and Cd) found in well waters (north central province of Sri Lanka, India, Korea, Chile and Bangladesh) or surface water bodies (Chile, Africa, China India and Bangladesh)which are in close proximity with agricultural lands or industrial zones or waste dumping areas (chemical or electronic). Several acute and chronic effects are being recorded. This book reviews heavy metals, sources, effects and remediation techniques in general.




Heavy Metal Toxicity in Public Health


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.







Heavy Metals and Health


Book Description

Heavy metals are persistent in the environment and their elevated emission during longer periods of time can cause contamination of the environment. They are emitted in all environmental media, but can also be easily transported between them due to the atmospheric deposition, water runoff, etc., and thus accumulate in the environment or penetrate the food chains. The main routes of human exposure to heavy metals are through ingestion, inhalation or via dermal contact. Hence, there is a need for better understanding of absorption, distribution and deposition of heavy metals in the human body. This information is of a crucial importance for the evaluation of heavy metal potential health implications. In this book, Chapter One provides an overview of the heavy metal health hazards, presented as a consequence of heavy metal pollution, their availability and cycling between different media in the environment. Chapter Two comprehensively discusses the roles and harmful effects of heavy metals on human health, as well as the sources and techniques of removing heavy metals from the environment. Chapter Three explores the mechanisms of mercury cardiovascular toxicity, with a particular emphasis on its effects toward endothelial cells. Chapter Four focuses on the effects of exposure to soil contaminated by metals. Chapter Five examines antimicrobial functionalized textiles. Chapter Six discusses thallium poisoning. Chapter Seven provides a review of heavy metal pollution, human exposure and public health implications in Nigeria.
