Environmental Heavy Metal Pollution And Effects On Child Mental Development

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.

Download or read book Pediatric Neurotoxicology written by Cynthia A. Riccio and published by Springer. This book was released on 2016-08-10 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on children and the impact of neurotoxins on the developing brain to guide the practice of psychologists working with children in clinical and school settings. Each chapter covers a distinct neurotoxin or group of neurotoxins, with particular emphasis on the impact of the neurotoxin exposure on the developing brain and long-term cognitive and psychosocial outcomes. This is more complex than studying neurotoxins with adults because of the rapid development occurring in the child's brain. Further, children are more susceptible than adults to the effects of neurotoxins due to their developmental status. Many of the effects discussed in this volume occur in utero, thus setting the stage for an altered developmental trajectory.

This book was released on 2021-01-22 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic is part of the Aquatic Physiology, Environmental Pollution, Nanotoxicology and Phytoremediation series: Aquatic Physiology, Environmental Pollution, Nanotoxicology and Phytoremediation, Volume II Environmental pollution as a result of increasing industrialization is a major problem worldwide. The toxicity of the chemicals, hazards, radiation, and environmental stressor to the aquatic fauna was studied. Although, recently, the excess levels of wastes discharged in water caused severe toxicity in aquatic environments and their fauna, still there is some shortage in the nanotoxicology and phytoremediation studies. So, the aim of this Research Topic is to create some knowledge about the environmental pollution and remediation in aquatic environment in collaboration with experts in physiology, biochemistry, endocrinology, morpho-histology of aquatic fauna. The relation between physiology and other research fields is strong enough as all researchers in biology field use some extent physiological parameters to evaluate the organisms’ health status in normal and stressful conditions. In addition, physiology with endocrinology and neurology can provide a contribution on the endocrine stress response of aquatic vertebrates and regulate the responses of vertebrates to stressors. Whilst the physiology of most aquatic animals has been well studied, not many articles provide sufficient data that helps understanding the common bases of the stress response after exposure to environmental pollutants and mechanisms of action. Such approach needs to be taken both in terms of comparative responses among vertebrates but also among classes or orders within groups of vertebrates. Another aspect that has not been sufficiently approached so far is physiological stress response in relation to immunity, growth, reproduction or behavior and embryology of the aquatic organisms, which expands the knowledge on the interactions between physiological systems to build an overall stress response.

Download or read book Biomarkers of Toxic Metals written by Vanda Maria Falcão Espada Lopes de Andrade and published by CRC Press. This book was released on 2023-08-04 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current exposure of human populations to toxic metals makes the prevention and control of such exposures crucial. Biomarkers are undoubtably recognized as vital tools to achieve these goals. This book is for researchers, toxicologists, physicians, pharmacologists and those working in governmental regulatory agencies and other public health fields. The first part of this book covers general aspects of biomarkers of toxic metals, while parts 2 and 3 cover biomarkers of xenobiotic metals and essential metals with potential for toxicity, respectively. In part 4, novel approaches to metal biomarkers are focused.

Download or read book Microbial Strategies for Vegetable Production written by Almas Zaidi and published by Springer. This book was released on 2017-06-13 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​This book provides a comprehensive information on basic and applied concepts of microbesial strategies adopted for the improvement of vegetables grown in various production systems. The beneficial role of soil microbes including plant growth promoting rhizobacteria (PGPR), nitrogen fixers, and phosphate-solubilizing bacteria in the improvement of vegetables grown both in normal and contaminated soils is discussed. The role of PGPR in tomato production is dealt separately. The impact of heavy metals on different vegetables and abatement of metal toxicity following metal tolerant PGPR and their consequential impact on vegetables grown in metal polluted soil is discussed. Moreover, recent advances in the management of vegetable diseases employing PGPR are addressed. This volume is therefore of special interest to both academics, professionals and practitioners working in the field of vegetable farming/horticulture, microbiology and plant protection sciences.
