Download or read book A Practical Guide to Toxicology and Human Health Risk Assessment written by Laura Robinson and published by John Wiley & Sons. This book was released on 2018-11-20 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxicology – the study of the adverse effects of chemicals on living organisms is the cornerstone to all aspects of chemical safety and knowledge of the subject is needed in a wide spectrum of fields from the chemical industry to medicine, emergency services, forensics, and regulatory science. Toxicology involves the study of symptoms, mechanisms, treatments and detection of poisoning ... especially the poisoning of people. The many problems arising from a poor understanding of toxicology and its applications in hazard communication and chemical safety motivated the author's training courses and webinars, leading to this valuable book. Providing a practical and accessible guide, A Practical Guide to Toxicology and Human Health Risk Assessment enables readers to quickly build up knowledge and understanding of toxicology and its use in hazard identification, which is a fundamental part of chemical risk assessment. The book also covers current toxicological testing strategies and the use of physicochemical test data in hazard identification and exposure assessment. Examples are provided throughout the book to highlight important issues along with a summary of the key points that have been covered in each of the respective chapters. The book concludes with a listing of online resources on toxicology and risk assessment.

Download or read book Neurotransmitters and Toxicology written by Kevin Woodward and published by Royal Society of Chemistry. This book was released on 2024-05-01 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurotransmitters are usually considered to be endogenous substances that are released from neurons, act on receptor sites that are typically present on membranes of postsynaptic cells and produce a functional change in the properties of the target cell. They are essential features of the nervous systems of all animals, and numerous chemicals can act as neurotransmitters either intentionally (e.g. pesticides) or unintentionally (neurotoxins). The most common forms of neurotoxicity are the death of neurons, degeneration of axons, damage to glial cells and interference with the axonal membrane or neurotransmission. Important neurotoxins are found among pesticides, metals, solvents, natural substances, and industrial chemicals. Environmental chemicals may also contribute to the pathology of neurodevelopmental, neuropsychiatric, and neurodegenerative disorders. Neurotransmitters and Toxicology will be particularly appealing to toxicologists interested in neurotoxicology in various sub-disciplines, as well as neuro-chemists interested in pathology and disease mechanisms associated with neurotoxicants.

Download or read book Regulatory Toxicology in the European Union written by Tim Marrs and published by Royal Society of Chemistry. This book was released on 2018-02-21 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book European Partnership on the Assessment of Risks from Chemicals PARC Focus on New Approach Methodologies NAMs in Risk Assessment written by Terje Svingen and published by Frontiers Media SA. This book was released on 2024-08-21 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Partnership on the Assessment of Risks from Chemicals (PARC) project was launched in 2022. The overarching aim of this partnership is to enhance our knowledge about chemical substances to better safeguard human health and the environment against harmful effects. The project will run for seven years under Horizon Europe. PARC is subdivided into several work packages (WPs). WP5 is focused on hazard assessment for human and environmental health and includes more than 80 partners across Europe. WP5 aims to fill data gaps for specified chemical substances of concern (e.g, bisphenol alternatives) and to develop or improve new approach methodologies (NAMs) for chemical hazard assessment. This is in order to progress towards a risk assessment paradigm relying less on animal toxicity data, both with respect to human health and environmental safety. As the PARC initiative will evolve over time with respect to both projects and activities, presenting early initiatives will foster an increased awareness of ongoing activities and potential incorporation of new activities going forward.

Download or read book Food Safety Assessment Of Pesticide Residues written by Arpad Ambrus and published by World Scientific. This book was released on 2017-01-05 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides are now accepted as an integral part of modern agricultural production. This book provides analysis of the steps taken by national and international bodies working towards a cohesive global strategy for evaluating the safety of residues in food that result from approved pesticide uses. Also described is the role of the UN Food and Agriculture Organization (FAO), World Health Organization (WHO) and Codex Alimentarius in developing standards that protect the health of the consumers and ensure fair practices in the food trade. It goes on to look at the promotion of good agricultural practice in the use of pesticides and the need for control in their practical use. These include sampling, testing the compliance of marketed products against legal limits and verifying the effectiveness of the safety-based regulatory measures. This is a specialist book for those looking to go into the field of international food safety, for students and lecturers studying the topic, for policy makers working on public health and agricultural issues, and personnel responsible for taking samples and performing the analysis of pesticide formulations and residues.
