Available in PDF, EPUB and Kindle. Book excerpt: Nematodes are the most wide spread multicellular animals in Nature and analysis of nematodes in terrestrial, freshwater and marine environments as well as their role and function in ecosystems can be used for environmental monitoring. Classical and molecular approaches to nematode community analysis will be addressed and the contemporary field of nematodes as biosensors and genomic and post genomic aspects of nematode bioindicators will also be included. Case studies stress the importance of these bioindicators and demonstrate the commercial potential of these technologies.
Download or read book Endocrine Disrupters written by Peter Matthiessen and published by John Wiley & Sons. This book was released on 2013-02-04 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enables researchers to assess the effects of endocrine disrupters as well as comply with new environmental regulations Endocrine disrupters are chemicals both man-made and natural that interfere with the body's endocrine system, potentially resulting in adverse developmental, reproductive, neurological, and immune effects. In recent years, a number of regulatory authorities around the world have drafted or enacted legislation that requires the detection and assessment of the effects of endocrine disrupters on both humans and wildlife. In response, this book provides comprehensive, up-to-date information on the latest tested and proven methods used to detect and assess the environmental hazards posed by endocrine-disrupting chemicals. Endocrine Disrupters is divided into chapters covering each major taxon as well as chapters dedicated to hazard assessment and regulation. The book covers testing methods for all the vertebrate groups and several invertebrate phyla, including: Crustaceans and mollusks Insects Fish Amphibians and reptiles Birds and mammals Moreover, the book emphasizes practical, ethical testing methods that combine sensitivity, efficiency, statistical power, and reasonable cost. Each chapter is written by one or more international experts in ecotoxicology, offering readers step-by-step guidance for implementing each method based on the latest research and the authors' firsthand laboratory experience. Furthermore, all the chapters have been subjected to a rigorous peer review and edited in light of the reviewers' comments. References at the end of each chapter guide readers to the literature in the field. Endocrine Disrupters is recommended for scientists who need to test chemicals for possible endocrine-disrupting properties. It is also recommended for regulatory authorities who need to decide whether particular chemicals can be safely marketed.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical substances, physical agents and built structures exhibit various types of hazard due to their inherent toxic, mutagenic, carcinogenic, reprotoxic and sensitizing character or damaging to the immune and hormone system. The first steps in managing an environment contaminated by chemical substances are characterization of hazards and quantifi
Download or read book Environmental Risk Analysis for Asian Oriented Risk Based Watershed Management written by Minoru Yoneda and published by Springer. This book was released on 2018-05-07 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is a practical guidebook on environmental risk assessment, especially for watershed-scale management. It highlights case studies of watershed environmental risk in Malaysia, including the potential health risks as well as screening methods and management in practice. In order to apply environmental risk assessment methods for the management of toxic chemicals, it is necessary to consider the geological and climate features of each country as well as their cultural characteristics. Focusing on Malaysia as a representative country, the book also discusses studies in other Asian countries. The insights provided can be applied to advanced and developing countries alike. A suitable textbook for graduate students, it is also a valuable reference source for researchers, practitioners and policymakers.

Download or read book Phenotypic Plasticity of Insects written by Douglas Whitman and published by CRC Press. This book was released on 2009 with total page 914 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the profound importance of phenotypic plasticity as a central organizing theme for understanding biology. Chapters take a broad, integrative approach to explain how physical and biological environmental stimuli (temperature, photoperiod, nutrition, population density, predator presence, etc.), influence insect biochemical, physiological, learning, and developmental processes, altering phenotype, which then influences performance, ecology, life-history, survival, fitness, and subsequent evolution. Topics include endocrinology, development, body size, allometry, polyphenism, reproduction, reproductive and life-history tradeoffs, alternative mating and life-history strategies, density-dependent prophylaxis, physiological adaptation, acclimation, homeostasis, heat-shock proteins, learning, adaptive anti-predator behavior, and evolution of phenotypic plasticity.

Download or read book Environmental Hygiene written by Norbert H. Seemayer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental pollution raises serious concern worldwide about effects on human health. Based on a recent meeting, this book focuses on diverse aspects of environmental hygiene, dealing with the evaluation of chemical and physical agents and their relevance to human health. To assess the toxicity, mutagenicity and carcinogenicity of environmental pollutants, a variety of methodological approaches, both in vivo and in vitro, as tissue cultures, isolated organs and animal models, were developed and are described in detail. Data on human exposure, biological monitoring and epidemiological studies are also included. Problems of environmental control and legislation as well as possible provisional steps are discussed.
