The knowledge of metal ion speciation is essential for predicting the exact toxicities of metal ion species in the environment. Metal ions can exist in various oxidation states, each of which possesses different physical and chemical properties as well as exhibit varying toxicities. Often, toxicity data is unreliable because it is based on metal ion concentration measurements that fail to identify a dominant species either more or less harmful than the average. Instrumental Methods in Metal Ion Speciation provides analytical techniques and experimental methodologies for determining the concentration of the different physicochemical forms of metal ions in environmental and biological samples, leading to more accurate measurements of actual toxicity.

The authors introduce the principles of metal ion speciation and discuss important analytical techniques such as gas and liquid chromatography, capillary electrophoresis, and both electrochemical and radiochemical methods used to determine concentration and composition. They present a range of liquid chromatographic approaches, including capillary electrochromatography and high-performance, ion, ion pair, micellar electrokinetic, size exclusion, chiral, and supercritical fluid chromatographies for all metal ion species. Comprehensive in scope, the text covers the sources, distribution, toxicity, biotransformation, and biodegradation of each metal ions species as well as extraction methods, sample preparation, and experimental optimization techniques that can be useful in designing future experiments.

Instrumental Methods in Metal Ion Speciation is a unique and valuable source of reference for scientists, academics, and researchersinvolved in analytical, biological, pharmaceutical, and environmental chemistries, as well as material industries, geochemistry, agriculture, biotechnology, and occupational safety and regulations.

This book presents the structure of the main toxins of aquatic origin, their distribution, producing species and vectors, their mechanisms of action, the clinical aspects of envenomation in humans, their effects in laboratory or wild animals, their toxicokinetic properties, including the relevant treatment, detection methods and regulatory aspects for management. The work also presents the main species associated with the injuries, poisonings their toxins, mechanism of action and the clinical aspects of the envenomations by aquatic animals and discusses the actual measures utilized in the first aid and hospital treatments. Marine toxins such as palytoxins, brevetoxins, saxitoxin, ciguatoxins, okadaic acid, azaspiracid toxins, equinatoxins are also dealt with in this volume. These toxins can be lethal as well as having a complex and large molecular structure and display mechanisms by which they act very specifically on targets, receptors or on critical body proteins. The marine and freshwater environments are the new frontiers of humanity, but the increase of economic and tourist activities provoke nasty encounters between aquatic animals and humans. The main victims are swimmers, professional and sportive fishermen, surfers and scuba divers as well as people working in related fields. The identification, knowledge and treatment of envenomations caused by venomous and poisonous animals are not adequate and the prevention of injuries still is not possible. Additionally, the immense potential of the pharmacologic effects of their toxins is not fully explored. Toxins of venomous aquatic animals can cause proteolysis, myotoxicity, hemotoxicity (mainly hemolysis), cytotoxicity and neurotoxicity. The neurotoxicity is generally associated with toxins of dinoflagellates and cyanobacteria, present in poisonous and/or contaminated invertebrates and fish.

This book will be written by experts for professionals, scientists and all those involved in toxicological data generation and decision-making. It is the updated and expanded version of a monograph published in German in 2004. Chemical safety is regulated on various levels including production, storage, transport, handling, disposal or labelling. This book deals comprehensively with the safety-ensuring methods and concepts employed by regulatory agencies, industry and academics. Toxicologists use experimental and scientific approaches for data collection, e.g. about chemical hazards, physicochemical features or toxicokinetics. The respective experimental methods are described in the book. Toxicologists also deal with much insecurity in the exposure and effect scenarios during risk assessment. To overcome these, they have different extrapolation methods and estimation procedures at their disposal. The book describes these methods in an accessible manner. Differing concepts from one regulation area to another are also covered. Reasons and consequences become evident when reading the book. Altogether, the book Regulatory Toxicology will serve as an excellent reference."

Initially, because of the inadequate sensitivity of devices and other limitations, only major venom components of the dominant species were studied. However, in last two decades, increased sensitivity of devices and the development of new techniques, such as transcriptomics and proteomics techniques, have permitted us to analyze the structures and functions of rare species and to identify novel minor components. As a result, the number of venom components identified is increasing dramatically and the physiological functions of each component is more deeply understood. The scope of this book provides the readers an updated and comprehensive presentation on snake venoms. The subjects are divided into six sections, starting with the overview of snake venom compositions in Malaysian species, followed by description of enzymes and enzyme inhibitors contained in snake venoms. Also discussed are the effects of snake venom on cellular receptors, ion channels, blood, and lymph, as well as cytotoxic and antimicrobial molecules present in snake venoms. The last section covers the clinical consequences of envenomation and the management of snakebites using antivenins.

A comprehensive guide to general strategies and specific methods for testing the immunotoxicity of chemicals in animal models and humans. Addressed to those seeking a basic introduction to the field as well as specialist researchers the book takes its focus from growing concern in scientific and public communities about the capacity of environmental agents to disrupt normal immune functions and thus increase susceptibility to tumours and infectious diseases. Compounds known to adversely affect the immune system are numerous and include drugs pesticides solvents halogenated and aromatic hydrocarbons and metals. The book draws on considerable recent progress in understanding the immunological consequences of chemical insults as well as increasingly sophisticated methodologies for assessing such effects. Close to 1000 references are included in this authoritative guide. The book opens with a detailed basic introduction to immunotoxicology. An extensive explanation of the function histophysiology and pathophysiology of the immune system emphasizes features that can aid the understanding and interpretation of the pathological changes caused by immunotoxic insults. Chapter two on the health impact of selected immunotoxic agents gives illustrative examples for some 30 chemicals that have been shown to exert immunotoxic effects in laboratory animals and for an additional seven groups of chemicals known to disturb immune functions in humans. For each brief discussions illustrate the chemical's distinct immunosuppressive properties and the mechanisms by which it exerts its toxic effects on the immune system. Chapter three provides detailed descriptions of a number of tests used in a tiered approach to the assessment of immunotoxicity. Against this background specific nonfunctional and functional tests for the assessment of immunotoxicology in experimental animals are presented and explained in full detail. Information on individual tests includes an explanation of why the test is important the types of data it can yield and exactly how it should be performed. Also included are sections offering advice on assessments in non-rodent species "in vitro "approaches and approaches using biomarkers in epidemiological studies and monitoring. The chapter concludes with a discussion of good laboratory practices for immunotoxicology studies and procedures for the validation of tests. Chapter five explains the much more complicated procedures needed to assess immunotoxicity in humans. An explanation of general questions to be considered when designing epidemiological studies is followed by presentation of three recommended testing schemes proposed by WHO and other agencies for preliminary evaluation of individuals exposed to immunotoxicants. Specific assays for assessing immune status are also described. The final chapter outlines a step-by-step process of risk assessment specific to the evaluation of potentially immunotoxic chemicals.
