Titelbeschreibung

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.

Back cover copy

The REACH (Registration, Evaluation, Authorisation & restriction of CHemicals) Regulation governs the manufacture and use of chemicals in the European Union (EU), and has a major impact on all aspects of the chemical industry. This book explains, in terms that are understandable to non-experts, what the Regulation requires, accurately, completely and concisely. The content is designed to be of use to a wide readership including: • Business managers – needing to understand the commercial impacts • Scientists – planning work programmes for assessment of hazard and risk • Product stewards – considering the implications of placing substances on the EU market • Users of chemicals – understanding information needs • Consultants – requiring a guide to help them to advise their clients Produced by well-known expert consultants, this manual offers a route through REACH in a single text. Also including references to official sources and special sections on green chemistry and alternatives, this book will prove invaluable to those working in or for the chemicals supply chain.
