Book Description
The OECD Guidelines for the Testing of Chemicals is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. They are a set of tools for professionals, used primarily in regulatory safety testing and subsequent chemical and chemical product notification, chemical registration and in chemical evaluation. They can also be used for the selection and ranking of candidate chemicals during the development of new chemicals and products and in toxicology research. This group of tests covers environmental fate and behaviour. In 2017, the section 3 "Degradation and Accumulation" was renamed to " Environmental fate and behaviour" to take into account Test Guidelines measuring endpoints such as dispersion, aggregation.

Book Description
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.

Book Description
This book discusses bioavailability concepts and methods, summarizing the current knowledge on bioavailability science, as well as possible pathways for integrating bioavailability into risk assessment and the regulation of organic chemicals. Divided into 5 parts, it begins with an overview of chemical distribution in soil and sediment, as well as the bioavailability and bioaccumulation of chemicals in plants, soil, invertebrates and vertebrates (including humans). It then focuses on the impact of sorption processes and reviews bioavailability measurement methods. The closing chapters discuss the impact of bioavailability studies on chemical risk assessment, and highlights further research needs. Written by a multi-disciplinary team of authors, it is an essential resource for scientists in academia and industry, students, as well as for authorities.

Book Description
This book focuses on the principles, methods, and interpretation involved in establishing the safety, risk, and hazard assessment of small molecules. It presents the regulatory requirements for risk and hazard identification as per the guidelines of the Organization for Economic Cooperation and Development (OECD), Paris, and the International Council for Harmonisation (ICH) of Technical Requirements for Pharmaceuticals for Human Use ICH and Schedule ‘Y’, India. It serves as reference material for undergraduate and postgraduate pharmacy degree students as well as senior researchers to learn about the principles, methods, and interpretations of systemic dosage (acute and repeated dose) and genotoxicity (in vitro and in vivo), special toxicological investigations such as reproductive and developmental toxicology, carcinogenicity, and toxicokinetics using animal models or in vitro methods, as applicable. This book is the first of its kind in providing information on the principles and methods of implementation of Good Laboratory Practice based on the guidelines of OECD. It includes detailed chapters about the regulatory requirements and guidelines in pharmaceutical products and agrochemicals. It also describes the infrastructure needed for preclinical studies, including in vivo and in vitro facilities.

Book Description
This practical manual provides basic theoretical knowledge about fermentative processes, biochemical laboratory techniques, and an arsenal of practical tricks, recipes, do’s, and don’ts for the biogas plant manager. It explains why some popular tests and techniques are unreliable, how to optimize the feedstock’s cost and the energy self-consumption of the digester, and how to analyze experimental error propagation and judge whether a marketing claim or a test result from the literature is correct. All examples are taken from the author’s experience as consultant in managing biogas plants in Italy and Spain. It features a glossary of technical jargon and useful reference tables and formulae. By following the procedures described in this manual, anybody can learn in short time how to become a "bacteria farmer."
