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.
In the past several decades, there has been a substantial increase in the availability of in vitro test methods for evaluating chemical safety in an international regulatory context. To foster confidence in in vitro alternatives to animal testing, the test methods and conditions under which ...
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.
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.
The method described in this Test Guideline is based on soil column chromatography in disturbed soil. Two types of experiments are performed to determine (i) the leaching potential of the test substance, and (ii) the leaching potential of ...
The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) addresses classification and labelling of chemicals by types of hazards. It provides the basis for worldwide harmonization of rules and regulations on chemicals and aims at enhancing the protection of human health and the environment during their handling, transport and use by ensuring that the information about their physical, health and environmental hazards is available. The seventh revised edition of the GHS which includes, inter alia, revised criteria for categorisation of flammable gases within Category 1; miscellaneous amendments intended to clarify the definitions of some health hazard classes; additional guidance to extend the coverage of section 14 of the Safety Data Sheets to all bulk cargoes, regardless of their physical state, transported under IMO instruments; revised and further rationalized precautionary statements in Annex 3; and a new example in Annex 7 addressing labelling of small packagings with fold-out labels.

Advanced Oxidation Processes (AOPs) rely on the efficient generation of reactive radical species and are increasingly attractive options for water remediation from a wide variety of organic micropollutants of human health and/or environmental concern. Advanced Oxidation Processes for Water Treatment covers the key advanced oxidation processes developed for chemical contaminant destruction in polluted water sources, some of which have been implemented successfully at water treatment plants around the world. The book is structured in two sections; the first part is dedicated to the most relevant AOPs, whereas the topics covered in the second section include the photochemistry of chemical contaminants in the aquatic environment, advanced water treatment for water reuse, implementation of advanced treatment processes for drinking water production at a state-of-the art water treatment plant in Europe, advanced treatment of municipal and industrial wastewater, and green technologies for water remediation. The advanced oxidation processes discussed in the book cover the following aspects: - Process principles including the most recent scientific findings and interpretation. - Classes of compounds suitable to AOP treatment and examples of reaction mechanisms. - Chemical and photochemical degradation kinetics and modelling. - Water quality impact on process performance and practical considerations on process parameter selection criteria. - Process limitations and byproduct formation and strategies to mitigate any potential adverse effects on the treated water quality. - AOP equipment design and economics considerations. - Research studies and outcomes. - Case studies relevant to process implementation to water treatment. - Commercial applications. - Future research needs. Advanced Oxidation Processes for Water Treatment presents the most recent scientific and technological achievements in process understanding and implementation, and addresses to anyone interested in water remediation, including water industry professionals, consulting engineers, regulators, academics, students.
