Mycotoxins are increasingly attracting attention at thegovernmental, public and academic level worldwide, due to more frequent and serious contaminations of food and feedstuffs, which pose a serious threat to human health and animal production. This book reviews the latest research on mycotoxins that directly concern food safety, and especially focuses on detection technologies, risk assessment and control strategiescurrently being used in China. Gathering contributions from over 20 respected researchers, the book will benefit graduatestudents, researchers and management groups from various disciplines, including food science and technology, analytical chemistry, plant pathology, public health, etc.
This book closes a current gap by providing the scientific basis for consumer exposure assessment in the context of regulatory risk assessment. Risk is defined as the likelihood of an event occurring and the severity of its effects. The margin between the dose that leads to toxic effects and the actual dose of a chemical is identified by estimating population exposure. The objective of this book is to provide an introduction into the scientific principles of consumer exposure assessment, and to describe the methods used to estimate doses of chemicals, the statistics applied and computer tools needed. This is presented through the backgrounds of the special fields in exposure analysis, such as exposure via food and by the use of consumer products, toys, clothing and other items. As a general concept, human exposure is also understood to include exposure via the environment and from the work setting. In this context, the specific features of consumer exposure are pointed out and put into the context of regulation, in particular food safety, chemicals safety (REACh) and consumer product safety. The book is structured into three parts: The first part deals with the general concepts of consumer exposure as part of the overall risk analysis framework of risk characterization, risk assessment and risk communication. It describes the three basic features of exposure assessment (i) the exposure scenario (ii) the exposure model and (iii) the exposure parameters, addressing external and internal exposure. Also, the statistical presentation of data to characterize populations, in connection with variability, uncertainty and quality of information and the presentation of exposure evaluation results is described. The second part deals with the specific issues of exposure assessment, exposure via food consumption, exposure from use of consumer products, household products, toys, cosmetic products, textiles, pesticides and others. This part also covers methods for acquisition of data for exposure estimations, including the relevant information from regulations needed to perform an accurate exposure assessment. The third part portrays a prospect for further needs in the development and improvement of consumer exposure assessment, as well as international activities and descriptions of the work of institutions that are involved in exposure assessment on the regulatory and scientific level. And conversely, it creates the rationale for the exposure assessment details necessary to satisfy regulatory needs such as derivation of upper limits and risk management issues.
Consumer and environmental protection depend on the careful regulation of all classes of chemicals. Toxicology is the key science used to evaluate safety and so underpins regulatory decisions on chemicals. With the growing body of EU legislation involved in chemical regulation, there is a concomitant need to understand the toxicological principles underlying safety assessments Regulatory Toxicology in the European Union is the first book to cover regulatory toxicology specifically in Europe. It addresses the need for a wider understanding of the principles of regulatory toxicology and their application and presents the relationship between toxicology and legislative processes in regulating chemical commodities across Europe. This title has a broad scope, covering historical and current chemical regulation in Europe, the role of European agencies and institutions, and also the use of toxicology data for important classes of chemicals, including human and veterinary medicines, animal feed and food additives, biocides, pesticides and nanomaterials. This book is therefore extremely pertinent and timely in the toxicology field at present. This book is an essential reference for regulatory authorities, industrialists, academics, undergraduates and postgraduates working within safety and hazards, toxicology, the biological sciences, and the medicinal and pharmaceutical sciences across the European Union.
This guidance document was originally published in 2012 and updated in 2018 to reflect new and updated OECD test guidelines, as well as reflect on scientific advances in the use of test methods and assessment of the endocrine activity of chemicals.
Nanotechnology has the potential to change every part of our lives. Today, nanotechnology-based products are used in many areas, and one of the most important areas is drug delivery. Nanoparticulate drug delivery systems not only provide controlled delivery of drugs and improved drug solubility but also improve drug efficiency and reduce side effects via targeting mechanisms. However, compared with conventional drug delivery systems, few nanoparticle-based products are on the market and almost all are nontargeted or only passively targeted systems. In addition, obtaining targeted nanoparticle systems is quite complex and requires several evaluation mechanisms. This book discusses the production, characterization, regulation, and currently marketed targeted nanoparticle systems in a broad framework. It provides an overview of targeted nanoparticles’ (i) in vitro characterization, such as particle size, stability, ligand density, and type; (ii) in vivo behavior for different targeting areas, such as tumor, brain, and vagina; and (iii) current advances in this field, including clinical trials and regulation processes.
The one-stop resource for health protection professionals, environmental scientists and safety engineers. Since the entire 40-volume Ullmann's Encyclopedia is inaccessible to many readers - particularly individuals, smaller companies or institutes - all the information on industrial toxicology, ecotoxicology, process safety as well as occupational health and safety has been condensed into this convenient 2-volume set. Based on the latest online edition of Ullmann's containing articles never been before in print, this ready reference provides practical information on applying the science of toxicology in both the occupational and environmental setting, and explains the fundamentals necessary for an understanding of the effects of chemical hazards on humans and ecosystems. The detailed and meticulously edited articles have been written by renowned experts from industry and academia, and much of the information has been thoroughly revised. Alongside explanations of safety regulations and legal aspects, this set covers food additives, toxic agents as well as medical and therapeutical issues. Top-quality illustrations, clear diagrams and charts combined with an extensive use of tables enhance the presentation and provide a unique level of detail. Deeper insights into any given area of interest is offered by referenced contributions, while rapid access to a particular subject is enhanced by both a keyword and author index.
This text is divided into three parts. The first part describes basic toxicological concepts and methodologies used in aquatic toxicity testing, including the philosophies underlying testing strategies now required to meet and support regulatory standards. The second part of the book discusses various factors that affect transport, transformation, ultimate distribution, and accumulation of chemicals in the aquatic environment, along with the use of modelling to predict fate.; The final section of the book reviews types of effects or endpoints evaluated in field studies and the use of structure-activity relationships in aquatic toxicology to predict biological activity and physio-chemical properties of a chemical. This section also contains an extensive background of environmental legislation in the USA and within the European Community, and an introduction to hazard/risk assessment with case studies.
