Download or read book REACH for the Polymer Industry A Practical Guide written by Polymer REACH Consortium and published by Smithers Rapra. This book was released on 2012-01-16 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been produced by the EU Leonardo Project called Polymer REACH. The overall objective of Polymer REACH was to develop an e-learning platform and training materials for the European polymer industry to learn and understand how to manage their obligations under the European legislation - Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). This book forms part of the training materials which will complement the industry specific e-learning platform to enable the polymer industry to learn how to manage their obligations under REACH. The overall impact will be an increase in the knowledge base of the polymer industry on REACH, which will in turn help to increase competitiveness and sustainability of the sector. This book will be useful to anyone who works with polymers or the chemicals that are used to make polymers, whether they are end-users or suppliers. REACH is affecting everyone concerned with the polymer industry and this book will help them to prepare for the impact and consequences of the REACH legislation.

Download or read book Human and Ecological Risk Assessment written by Dennis J. Paustenbach and published by John Wiley & Sons. This book was released on 2024-04-15 with total page 1319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the fundamentals of human risk assessment with this introduction and reference Human risk assessments are a precondition for virtually all industrial action or environmental regulation, all the more essential in a world where chemical and environmental hazards are becoming more abundant. These documents catalog potential environmental, toxicological, ecological, or other harms resulting from a particular hazard, from chemical spills to construction projects to dangerous workplaces. They turn on a number of variables, of which the most significant is the degree of human exposure to the hazardous agent or process. Human and Ecological Risk Assessment combines the virtues of a textbook and reference work to introduce and analyze these vital documents. Beginning with the foundational theory of human health risk assessment, it then supplies case studies and detailed analysis illustrating the practice of producing risk assessment documents. Fully updated and authored by leading authorities in the field, the result is an indispensable work. Readers of the second edition of Human and Ecological Risk Assessment will also find: Over 40 entirely new case studies reflecting the latest in risk assessment practice Detailed discussion of hazards including air emissions, contaminated food and soil, hazardous waste sites, and many more Case studies from multiple countries to reflect diverse international standards Human and Ecological Risk Assessment is ideal for professionals and advanced graduate students in toxicology, industrial hygiene, occupational medicine, environmental science, and all related subjects.
