Download or read book Review of the Environmental Protection Agency s State of the Science Evaluation of Nonmonotonic Dose Response Relationships as they Apply to Endocrine Disruptors written by National Research Council and published by National Academies Press. This book was released on 2014-05-27 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potential health effects from chemicals that disrupt endocrine function pose an environmental health concern because of their ability to interfere with normal hormone function in human and wildlife populations. The endocrine system regulates biological processes throughout the body and is sensitive to small changes in hormone concentrations. Endocrine-disruptor research has focused primarily on chemicals that affect three hormone pathways that play important roles in reproduction and development - the estrogen, androgen, and thyroid hormone pathways. Some of this research has identified dose-response relationships that have nonmonotonic curves. Nonmonotonic dose-response curves (NMDRs) are of concern because they do not follow the usual assumption made in toxicology that as dose decreases the response also decreases. The existence of NMDRs has been a controversial topic for decades, and there has been considerable debate about their implications for how chemicals are tested and for how risks from such chemicals are assessed. Toxicity tests are designed to identify hazards and to characterize dose-response relationships, so tests are aimed at finding a (high) dose that elicits a response, and dose-response is explored by testing lower doses spaced to identify statistically a no- or lowest-observed-adverse-effect level. The concern for NMDRs is that such studies, as currently designed, might not detect the inflection of the dose-response curve if only a few doses are tested or if the change in inflection occurs below the range of doses tested. Another concern is that some NMDRs are found for biological effects that are not usually evaluated in toxicity tests. If current testing strategies are inadequate to account for NMDRs, changes to risk assessment practices might be necessary. To help address these issues, the U.S. Environmental Protection Agency (EPA) developed a draft State-of-the-Science Evaluation: Nonmonotonic Dose Responses as they Apply to Estrogen, Androgen, and Thyroid Pathways and EPA Testing and Assessment Procedures. EPA asked the National Research Council to conduct an independent review of this evaluation to ensure that it is scientifically sound and of high quality. Review of Environmental Protection Agency's State-of-the-Science Evaluation of Nonmonotonic Dose-Response as they Apply to Endocrine Disrupters evaluates whether EPA's evaluation presents a scientifically sound and high-quality analysis of the literature on NMDRs. This report reviews how well the EPA evaluation described how the assessment was performed, whether consistent methods and criteria were applied in the analysis of different evidence streams, and whether appropriate methods were applied to evaluating the evidence. The report makes recommendations to improve EPA's process and strengthen the evaluation.

With coverage of many subjects where information has not been readily available, Fowler’s is a resource you don’t want to be without. Fowler's Current Therapy format ensures that each volume in the series covers all-new topics with timely information on current topics of interest in the field. Focused coverage offers just the right amount of depth — often fewer than 10 pages in a chapter — which makes the material easier to access and easier to understand. General taxon-based format covers all terrestrial vertebrate taxa plus selected topics on aquatic and invertebrate taxa. Updated information from the Zoological Information Management System (ZIMS) includes records from their growing database for 2.3 million animals (374,000 living) and 23,000 taxa, which can serve as a basis for new research. Expert, global contributors include authors from the U.S. and 25 other countries, each representing trends in their part of the world, and each focusing on the latest research and clinical management of captive and free-ranging wild animals. NEW! All-new topics and contributors ensure that this volume addresses the most current issues relating to zoo and wild animals. NEW! Content on emerging diseases includes topics such as COVID-19, rabbit hemorrhagic disease, yellow fever in South American primates, monitoring herpesviruses in multiple species, and canine distemper in unusual species. NEW! Emphasis on management includes coverage of diversity in zoo and wildlife medicine. NEW! Panel of international contributors includes, for the first time, experts from Costa Rica, Estonia, Ethiopia, India, Norway, and Singapore, along with many other countries. NEW! Enhanced eBook version is included with each print purchase, providing a fully searchable version of the entire text and access to all of its text, figures, and references.

Book excerpt: More than 20 years after the ban of DDT and other organochlorine pesticides, pesticides continue to be detected in air, rain, soil, surface water, bed sediment, and aquatic and terrestrial biota throughout the world. Recent research suggests that low levels of some of these pesticides may have the potential to affect the development, reproduction,
Download or read book Physiology written by Ernest S. Chang and published by Oxford University Press. This book was released on 2015-03-27 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Crustacea is one of the dominant invertebrate groups, displaying staggering diversity in form and function, and spanning the full spectrum of Earth's environments. Crustaceans are increasingly used as model organisms in all fields of biology, as few other taxa exhibit such a variety of body shapes and adaptations to particular habitats and environmental conditions. Physiology is the fourth volume in The Natural History of the Crustacea series, and the first book in over twenty-five years to provide an overview of the comparative physiology of crustaceans. An understanding of physiology is crucial to a comprehension of the biology of this fascinating invertebrate group. Written by a group of internationally recognized experts studying a wide range of crustacean taxa and topics, this volume synthesizes current research in a format that is accessible to a wide scientific audience.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to examine comprehensively the chlorine industry and its effects on the environment. It covers not only the history of chlorine production, but also looks at its products, their effects on the global environment, and the international legislation which controls their use, release, and disposal. Individual chapters are dedicated to subjects such as releases of organochlorines into the environment, and the environmental impact of ozone depletion, providing simple explanations of these complex issues. These are backed up with case studies of landmark events in the history of the chlorine industry - for example the Seveso explosion or the Yusho and Yu-Cheng mass poisonings. With a clear, concise text and numerous compilations of critical data, this book will prove an invaluable source reference for environmental scientists, students, and policy makers with an interest in this subject.
