Book Description
Available online: https://pub.norden.org/temanord2023-508/ This is a timely revision and update of the Nordic report on existing default values and recommendation for exposure assessments, from 2011. The report aims to give an updated overview of non-chemical-specific exposure factors to be used by the authorities during the process of assessing exposure to both adults and children, especially in risk assessment in relation to REACH. This contributes towards a further harmonization of such exposure factors to be used in exposure assessments. In the report the recommended values for the non-chemical specific exposure factors are represented. The focus of this report is to be used in the context of REACH, however, the recommended values can also be used in the broader context of chemical regulations.

Book Description
Abstract: Default values are often used in exposure assessments e.g. in modelling because of lack of actually measured data. The quality of the exposure assessment outcome is therefore heavily dependent on the validity and representativeness this input data. Today the used default factors consist of a wide range of more or less well-documented values originating from many different sources. The purpose of this report is to give an overview and to evaluate exposure factors that are currently used by the authorities and industry in the exposure assessments for both adults (occupational and consumer exposure) and children in relation to REACH. Another important purpose of the report is to contribute towards a further harmonisation of exposure factors by giving recommendations of most valid and representative defaults. These recommendations can be used besides REACH also in biocide's and plant protection product's exposure assessments. The exposure default values were collected from the relevant European sources (ECHA, Consexpo, EUSES, Biocide TNsG, ECETOC, ExpoFacts) as well as from WHO and US-EPA. The following key default factors selected to the evaluation: body weight, body surface area, inhalation rate, soil and dust ingestion, drinking water, food intake, non-dietary ingestion factors, lifetime expectancy, activity factors and consumer products

Book Description
Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.

Book Description
The public depends on competent risk assessment from the federal government and the scientific community to grapple with the threat of pollution. When risk reports turn out to be overblownâ€"or when risks are overlookedâ€"public skepticism abounds. This comprehensive and readable book explores how the U.S. Environmental Protection Agency (EPA) can improve its risk assessment practices, with a focus on implementation of the 1990 Clean Air Act Amendments. With a wealth of detailed information, pertinent examples, and revealing analysis, the volume explores the "default option" and other basic concepts. It offers two views of EPA operations: The first examines how EPA currently assesses exposure to hazardous air pollutants, evaluates the toxicity of a substance, and characterizes the risk to the public. The second, more holistic, view explores how EPA can improve in several critical areas of risk assessment by focusing on cross-cutting themes and incorporating more scientific judgment. This comprehensive volume will be important to the EPA and other agencies, risk managers, environmental advocates, scientists, faculty, students, and concerned individuals.

Book Description
In order to assess the potential risks of chemical substances in consumer products, it is necessary to estimate the consumer exposure during product use. The computer tool ConsExpo is able to calculate indoor human exposure to chemical substances in products such as paint, cosmetics or cleaning agents. The General Fact Sheet describes default values useful for estimating the exposure to a chemical substance. By using these defaults, the exposure assessment is performed in a transparent and standardized way. Based on new available information and developments, RIVM updated the General Fact Sheet in the current report, which replaces the General Fact Sheet 2006. The General Fact Sheet contains default values for the room in which the exposure takes place (for example room size) and for the person that is exposed, such as body weight and the surface areas of different parts of the body. In addition, it presents information on the ventilation in houses. Similarly, information is provided on inhalation rates for adults and children while at rest and during exercise. New in this version of the fact sheet are data on activity patterns. The General Fact Sheet explains the underlying data leading to the defaults and the quality of the default values. Apart from the General Fact Sheet, there are various product-specific fact sheets, e.g. for paint, cosmetics, children toys, pest control products, do-it-yourself products, disinfection products and cleaning agents. These fact sheets contain information, e.g. on the exposure duration and amount of product used.

Book Description
The regulation of potentially hazardous substances has become a controversial issue. This volume evaluates past efforts to develop and use risk assessment guidelines, reviews the experience of regulatory agencies with different administrative arrangements for risk assessment, and evaluates various proposals to modify procedures. The book's conclusions and recommendations can be applied across the entire field of environmental health.
