Download or read book The Nature and Use of Ecotoxicological Evidence written by Michael C. Newman and published by Academic Press. This book was released on 2018-01-31 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nature and Use of Ecotoxicological Evidence: Natural Science, Statistics, Psychology, and Sociology examines how toxicologists and environmental professionals come to understand and make decisions about possible harm from pollutants. Drawing on concepts and techniques from the natural, social and mathematical sciences, the book emphasizes how pollutant-related evidence is gathered, assessed, communicated and applied in decision-making. Each chapter begins with a real-world example before exploring fundamental cognitive, social, statistical or natural science concepts to explain the opening example. Methods from other disciplines for recognizing, reducing or removing the influence of impediments in wise decision-making are highlighted in each chapter. Misreading evidence by the scientific community, and miscommunication to regulators and the public, remain major impediments to wise action in pollution issues. Which evidence comes to dominate the dialogue among scientists, regulators and decision makers depends on social and scientific dynamics. Yet psychological and sociological factors that influence the movement of evidence through scientific communities to regulators receive cursory discussion by professionals unfamiliar with the sociology literature. Toxicologists, environmental scientists, psychologists and professionals and students across the sciences will find the book useful for understanding how evidence is generated, assessed and communicated in their own fields. Includes groundbreaking research synthesizing information from across the sciences to understand the decision-making process Provides real life examples and uses theoretical concepts to analyze them in clear, direct language Encourages critical thinking about complex problems

Download or read book Statistical Models in Toxicology written by Mehdi Razzaghi and published by CRC Press. This book was released on 2020-05-21 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical Models in Toxicology presents an up-to-date and comprehensive account of mathematical statistics problems that occur in toxicology. This is as an exciting time in toxicology because of the attention given by statisticians to the problem of estimating the human health risk for environmental and occupational exposures. The development of modern statistical techniques with solid mathematical foundations in the 20th century and the advent of modern computers in the latter part of the century gave way to development of many statistical models and methods to describe toxicological processes and attempts to solve the associated problems. Not only have the models enjoyed a high level of elegance and sophistication mathematically, they are widely used by industry and government regulatory agencies. Features: Focuses on describing the statistical models in environmental toxicology that facilitate the assessment of risk mainly in humans. The properties and shortfalls of each model are discussed and its impact in the process of risk assessment is examined. Discusses models that assess the risk of mixtures of chemicals. Presents statistical models that are developed for risk estimation in different aspects of environmental toxicology including cancer and carcinogenic substances. Includes models for developmental and reproductive toxicity risk assessment, risk assessment in continuous outcomes and developmental neurotoxicity. Contains numerous examples and exercises. Statistical Models in Toxicology introduces a wide variety of statistical models that are currently utilized for dose-response modeling and risk analysis. These models are often developed based on design and regulatory guidelines of toxicological experiments. The book is suitable for practitioners or as use as a textbook for advanced undergraduate or graduate students of mathematics and statistics.
