Download or read book The Heavy Elements written by J. E. Fergusson and published by Pergamon. This book was released on 1990 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text provides a broad survey of the ten heavier elements of the p-block, which have a number of features in common as well as displaying periodic trends. Full comprehension of the chemistry of the elements is necessary before complete understanding of environmental and health effects is possible. In many texts, however, basic chemistry is avoided as too complex or uninteresting. The author's approach in this case is to use the disciplines of health and environmental science to enhance understanding of the chemistry and to provide students with an integrated approach to the influence of the elements on the world. Information is provided on concentrations, sources and speciation of the heavy elements and their effects on the health of human beings. The text is intended to stimulate students to investigate further aspects of the heavy elements, and contribute to this young but rapidly growing field.

Download or read book Effect of Heavy Metal Pollution on Plants written by N. W. Lepp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

Download or read book Heavy Metal Toxicity Environmental Concerns Remediation and Opportunities written by Rajeev Pratap Singh and published by Springer Nature. This book was released on 2023-10-24 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Environmental Heavy Metal Pollution and Effects on Child Mental Development written by Lubomir I. Simeonov and published by Springer Science & Business Media. This book was released on 2010-11-19 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

It provides a multi-disciplinary approach that integrates the physical and earth sciences with the social sciences, ecology and economics. Increasingly, graduates in the minerals industry and related sectors will not only require a deep technical and scientific understanding of their fields (such as geology, mining, metallurgy), but will also need a knowledge of how their industry relates to and can contribute to the transition to sustainability. Chapters 1 to 3 introduce the concept of materials, how they are used in society and the environmental basis of our existence. Chapter 4 introduces the concept of sustainability and the issues it raises for the use of non-renewable resources. Chapter 5 discusses the geological basis of the minerals industry and Chapter 6 describes the structure and nature of the industry. Chapters 7 and 8 review the technologies by which mineral resources are extracted from the Earth’s crust and processed. Chapters 9 and 10 examine the usage of energy and water. Chapters 11 and 12 survey the wastes resulting from the production of mineral and metal commodities, the human and environmental impacts of these, and how they are managed. Chapter 13 examines the recycling of mineral-derived materials and the role of secondary materials in meeting material needs. Chapter 14 surveys the potential future sources of minerals and the factors that determine long-term supply. Chapter 15 surveys the socio-economic and technological factors that determine the long-term demand for mineral-derived materials and future trends. Chapter 16 discusses how waste can be reduced, or eliminated, through technological developments and socio-political changes. Finally, Chapter 17 addresses the concept of stewardship and the role the minerals industry should play in the ongoing transition to sustainability. Minerals, Metals and Sustainability is an important reference for students of engineering and applied science and geology; practising engineers, geologists and scientists; students of economics, social sciences and related disciplines; professionals in government service in areas such as resources, environment and sustainability; and non-technical professionals working in the minerals industry or in sectors servicing the minerals industry.
