Download or read book A Framework to Guide Selection of Chemical Alternatives written by National Research Council and published by National Academies Press. This book was released on 2014-10-29 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, regulations governing chemical use have often focused on widely used chemicals and acute human health effects of exposure to them, as well as their potential to cause cancer and other adverse health effects. As scientific knowledge has expanded there has been an increased awareness of the mechanisms through which chemicals may exert harmful effects on human health, as well as their effects on other species and ecosystems. Identification of high-priority chemicals and other chemicals of concern has prompted a growing number of state and local governments, as well as major companies, to take steps beyond existing hazardous chemical federal legislation. Interest in approaches and policies that ensure that any new substances substituted for chemicals of concern are assessed as carefully and thoroughly as possible has also burgeoned. The overarching goal of these approaches is to avoid regrettable substitutions, which occur when a toxic chemical is replaced by another chemical that later proved unsuitable because of persistence, bioaccumulation, toxicity, or other concerns. Chemical alternative assessments are tools designed to facilitate consideration of these factors to assist stakeholders in identifying chemicals that may have the greatest likelihood of harm to human and ecological health, and to provide guidance on how the industry may develop and adopt safer alternatives. A Framework to Guide Selection of Chemical Alternatives develops and demonstrates a decision framework for evaluating potentially safer substitute chemicals as primarily determined by human health and ecological risks. This new framework is informed by previous efforts by regulatory agencies, academic institutions, and others to develop alternative assessment frameworks that could be operationalized. In addition to hazard assessments, the framework incorporates steps for life-cycle thinking - which considers possible impacts of a chemical at all stages including production, use, and disposal - as well as steps for performance and economic assessments. The report also highlights how modern information sources such as computational modeling can supplement traditional toxicology data in the assessment process. This new framework allows the evaluation of the full range of benefits and shortcomings of substitutes, and examination of tradeoffs between these risks and factors such as product functionality, product efficacy, process safety, and resource use. Through case studies, this report demonstrates how different users in contrasting decision contexts with diverse priorities can apply the framework. This report will be an essential resource to the chemical industry, environmentalists, ecologists, and state and local governments.

This book was released on 1997-05-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1950s and 1960s, the U.S. Army conducted atmospheric dispersion tests in many American cities using fluorescent particles of zinc cadmium sulfide (ZnCdS) to develop and verify meteorological models to estimate the dispersal of aerosols. Upon learning of the tests, many citizens and some public health officials in the affected cities raised concerns about the health consequences of the tests. This book assesses the public health effects of the Army's tests, including the toxicity of ZnCdS, the toxicity of surrogate cadmium compounds, the environmental fate of ZnCdS, the extent of public exposures from the dispersion tests, and the risks of such exposures.
Download or read book Risk Assessment Methods for Biological and Chemical Hazards in Food written by Fernando Pérez-Rodríguez and published by CRC Press. This book was released on 2020-10-28 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment has been extensively developed in several scientific fields, such as environmental science, economics, and civil engineering, among others. In the aftermath of the SPS and GATT agreements on the use of risk analysis framework in food trade, signed in the 1990s, international organisations and governments adopted risk assessment as a science-based process to ensure food safety along the food chain. The food industry can also benefit from the use of this approach for food process optimisation and quality assurance. Risk Assessment Methods for Biological and Chemical Hazards in Food introduces the reader to quantitative risk assessment methods encompassing general concepts to specific applications to biological and chemical hazards in foods. In the first section, the book presents food risk assessment as methodology and addresses, more specifically, new trends and approaches such as the development of risk rating methods, risk metrics, risk-benefit assessment studies and quality assessment methods. Section II is dedicated to biological hazards. This section identifies the most relevant biological hazards along the food chain and provides an overview on the types of predictive microbiology models used to describe the microbial response along the food chain. Chapter 12 specifically deals with cross contamination and the quantitative methods that can be applied to describe this relevant microbial process. The development and application of dose-response models (i.e. mathematical function describing the relationship between pathogen dose and health response) are also covered in this section. In Section III, the book translates risk assessment concepts into the area of chemical hazards, defining the process steps to determine chemical risk and describing the uncertainty and variability sources associated with chemicals. Key Features: Presents new trends and approaches in the field of risk assessment in foods Risk assessment concepts are illustrated by practical examples in the food sector Discusses how quantitative information and models are integrated in a quantitative risk asssment framework Provides examples of applications of quantitative chemical risk assessment in risk management The book, written by renowned experts in their field, is a comprehensive collection of quantitative methods and approaches applied to risk assessment in foods. It can be used as an extensive guide for food safety practitioners and researchers to perform quantitative risk assessment in foods
Download or read book Chemical Risk Assessment written by Peter Fisk and published by John Wiley & Sons. This book was released on 2014-01-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an essential guide and support to understanding of the science and policy, procedure and practice that underpins the REACH risk assessments required for the use and placing on the market of chemicals in the European Union. A clear understanding of information provision and how this affects the assessment of chemical safety is fundamentally important to the success of policy on chemicals and ultimately to the sustainability of the chemicals industry. Within the book, the scientific processes that underpin the policy are explained in a practical way. Importantly, it includes coverage of techniques to help solve the problems of using potentially risky and hazardous chemicals through the use of less hazardous alternatives and ‘green chemistry’, and also the analysis of the risks of the use of the most hazardous substances against the social and economic benefits of use. Chemical Risk Assessment: A Manual for REACH covers the following main themes: i) Assessment of chemical risk; ii) Risk management; iii) Hazard reduction, substitution and green chemistry; iv) Risk versus benefit – socio-economic analysis. The book acts as a practical guide and overview to chemicals risk assessment and risk management (in the EU context), as well as a support text for planning for the challenges of the future, which will see ever-increasing pressure to withdraw hazardous substances from the EU (and global) market, balanced against opportunities for innovation in the development of less hazardous chemicals.
Download or read book Chemical Mixtures and Combined Chemical and Nonchemical Stressors written by Cynthia V. Rider and published by Springer. This book was released on 2018-02-16 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, both basic and advanced concepts are discussed for considering mixtures from initial exposure characterization through evaluation of risk associated with combined exposures. This book will provide an introduction to key issues and multiple options for evaluating both the toxicity of mixtures as well as the risk associated with exposure to mixtures. Additionally, promising tools adapted from other disciplines will be discussed in the context of mixtures toxicology and risk assessment. Finally, the discussion will move beyond chemical mixtures to address incorporating non-chemical stressors into toxicity studies and cumulative risk assessments. Although exposure to multiple chemical and non-chemical stressors is the rule, not the exception, consideration of mixtures in toxicology and risk assessment continues to be a significant challenge. This book will be an essential resource for researchers and professionals in the fields of toxicology, epidemiology, exposure science, risk assessment, and statistics.
Download or read book Phthalates and Cumulative Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 2009-01-19 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: People are exposed to a variety of chemicals throughout their daily lives. To protect public health, regulators use risk assessments to examine the effects of chemical exposures. This book provides guidance for assessing the risk of phthalates, chemicals found in many consumer products that have been shown to affect the development of the male reproductive system of laboratory animals. Because people are exposed to multiple phthalates and other chemicals that affect male reproductive development, a cumulative risk assessment should be conducted that evaluates the combined effects of exposure to all these chemicals. The book suggests an approach for cumulative risk assessment that can serve as a model for evaluating the health risks of other types of chemicals.
Download or read book Handbook of Chemical Risk Assessment written by Ronald Eisler and published by CRC Press. This book was released on 2000-04-12 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written over a period of 17 years, the Handbook of Chemical Risk Assessment exhaustively examines and analyzes the world literature on chemicals entering the environment from human activities. The three volumes cover chemicals recommended by environmental specialists of the U.S. Fish and Wildlife Service and other resource managers. The choices were based on the real or potential impact of each contaminant and on the knowledge available about their mitigation. The information for each chemical includes source and use; physical, chemical, and metabolic properties; concentrations in field collections of abiotic materials and living organisms; deficiency effects; lethal and sublethal effects; and proposed regulatory criteria for the protection of human health and sensitive natural resources. Each chapter selectively reviews and synthesizes the technical literature on a specific priority contaminant and its effects on the environment. Successful risk assessment relies heavily on extensive and well-documented databases. They often include too much - or too little - information about too many chemicals. Of the hundreds of thousands of chemicals discharged into the environment, only a small number have sufficient information to attempt preliminary risk assessment. Sold only as a three volume set, the Handbook of Chemical Risk Assessment provides you with the exact amount of information you need in a single resource.
Download or read book Exposure and Risk Assessment of Chemical Pollution Contemporary Methodology written by Mahmoud A. Hassanien and published by Springer Science & Business Media. This book was released on 2009-03-31 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains the contributions at the NATO Study Institute on Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology, which took place in Sofia – Borovetz, Bulgaria, July 1–10, 2008. Rapid advances in mathematics, computer science and molecular biology and chemistry have lead to the development in of a new branch of toxicology called Computational Toxicology. This emerging field is addressing the estimation and prediction of exposure risk and effects of chemicals based on experimental data, measured concentration and biological mechanisms and computational models of biological systems. Mathematical models are also being used to predict the fate and transport of substances in the environment. Because this area is still in its infancy, there has been limited application from governmental agencies to regulating controllable processes, such as registration of new chemicals, determination of estimated exposure and risk based limits and maximum acceptable concentrations in different compartments of the environment – ambient air, waters, soil and food products. However, this is soon to change as the ability to collect, analyze and interpret the required information is becoming increasingly more efficient and cost effective. Full implementation of the new processes have to involve education on both part of the experimentalists who are generating the data and the models, and the risk assessors who will use them to better protect human health and the environment.
