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 with an interest in neurotoxicology in a variety of sub-disciplines, as well as neuro-chemists interested in pathology and disease mechanisms associated with neurotoxicants.

Toxicological Effects of Veterinary Medicinal Products in Humans is the first definitive guide to discuss the adverse effects of veterinary medicinal products in humans. The chapters focus on occupational safety and consumer issues and examine the circumstances under which exposure is likely to occur. To be in context, it reviews this against the background of adverse health effects from other sources in the veterinary and farming professions. The book examines adverse drug effects reported to regulatory agencies (mainly the FDA's Center for Veterinary Medicine) and then considers a series of individual drugs, including antibiotics, anaesthetics and organophosphorus compounds. The chapters also discuss the fundamental aspects of regulatory issues relating to safety assessment, and examine the manner in which user safety is assessed prior to authorisation/approval and what measures can be taken after authorisation/approval in the light of findings from pharmacovigilance activities. There is growing concern over the issue of antimicrobial resistance and the contribution made by veterinary medicinal products. This too is addressed along with the significance to human health and measures that can be taken to mitigate the effects (if any) of the use of antibiotics in animals e.g. prudent use measures. The book will be an essential resource for medical practitioners in hospitals and general practice, pharmaceutical industry scientists, analysts, regulators and risk managers.

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.
