Download or read book Chemical Risk Assessment written by Peter Fisk and published by John Wiley & Sons. This book was released on 2013-10-28 with total page 334 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.

Available in PDF, EPUB and Kindle. Book excerpt: Developed from the efforts of a multiyear, international project examining how persistent, bioaccumulative, and toxic (PBT) chemicals are evaluated and managed, Persistent, Bioaccumulative, and Toxic (PBT) Chemicals: Technical Aspects, Policies, and Practices focuses on improving the processes that govern PBTs. Incorporating science and policy literature—as well as interviews and panel discussions featuring experts from around the world—this book provides you with an international perspective of PBT policies (centering on Europe, Asia, and North America), and reveals major findings and recommendations for improving PBT science, laws, and policies. It includes case studies of specific chemicals, provides an introduction to the overall subject of toxic chemicals, and weighs in on science and policy expansion for PBTs. It also provides summary tables of important PBTs, and discussions on the number of PBTs in commerce, weight of evidence approaches, market deselection, and international management. The text: Assesses the history, current practice, and future of PBT management Considers the roles scientific data, modeling, and conventions play in identifying and regulating PBTs Explores the number of PBTs in commerce and the growing role of weight of evidence (WOE) in the making of PBT determinations Identifies issues that are likely to come up in WOE judgments Examines international, national, subnational, and regional PBT policies Includes a comprehensive and easy-to-understand analysis of PBT science and policy This book reviews the current science, policies, and practices surrounding the regulation of PBTs. It also provides relevant research, recommendations, and suggestions for improving the management and oversight of PBTs.

Chapters consider: developments in socio-economic sectors such as energy, industry, agriculture, transport and tourism; prominent environmental problems such as climate change, ozone depletion, air pollution and soil degradation; cross-cutting issues of biological diversity and human health impacts; and policy management aspects.
Download or read book Formulating Packaging and Marketing of Natural Cosmetic Products written by Nava Dayan and published by John Wiley & Sons. This book was released on 2011-06-15 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Balanced coverage of natural cosmetics, and what it really means to be "green" The use of natural ingredients and functional botanical compounds in cosmetic products is on the rise. According to industry estimates, sales of natural personal care products have exceeded $7 billion in recent years. Nonetheless, many misconceptions about natural products for instance, what "green" and "organic" really mean continue to exist within the industry. Formulating, Packaging, and Marketing of Natural Cosmetic Products addresses this confusion head-on, exploring and detailing the sources, processing, safety, efficacy, stability, and formulation aspects of natural compounds in cosmetic and personal care products. Designed to provide industry professionals and natural product development experts with the essential perspective and market information needed to develop truly "green" cosmetics, the book covers timely issues like biodegradable packaging and the potential microbial risks they present, the use of Nuclear Magnetic Resonance (NMR) to identify biomarkers, and chromatographic methods of analyzing natural products. A must-read for industry insiders, Formulating, Packaging, and Marketing of Natural Cosmetic Products provides the reader with basic tools and concepts to develop naturally derived formulas.
