Toxicological Risk Assessment of Chemicals
Unlike many existing books on toxicology that cover either toxicity of a particular substance or toxicity of chemicals on particular organ systems, Toxicological Risk Assessment of Chemicals: A Practical Guide lays out the principle activities of conducting a toxicological risk assessment, including international approaches and methods for the risk

Existing default values and recommendations for exposure assessment
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.
Toxicological Risk Assessment for Beginners
This book serves as a comprehensive introductory guide to the practical aspects of risk assessment. Chapters include clearly defined objectives and summaries. The book includes: hazard identification, dose-response, exposure assessment, risk characterization, chemical mixtures, epidemiology, emerging issues and global perspectives with accessible language. The book concludes with a set of hypothetical case studies. Toxicological Risk Assessment for Beginners aims not to create an expert, but rather to provide readers with their first understanding of the risk assessment topic. This book was designed with the student in mind. We simplify a complex process for beginners and balance theory with practical aspects, but remain fluid enough to increase difficulty with case studies. By incorporating an action based, step by step approach to learning the risk assessment process, this book provides its readers with an elementary understanding of how the risk assessment process is initiated, developed and finished, making it a valuable guide for graduate students, post-doctoral fellows and early career scientists in industry.
Existing Default Values and Recommendations for Exposure Assessment
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 contr...
