Chemical substances, physical agents and built structures exhibit various types of hazard due to their inherent toxic, mutagenic, carcinogenic, reprotoxic and sensitizing character or damaging to the immune and hormone system. The first steps in managing an environment contaminated by chemical substances are characterization of hazards and quantification of their risks. Chemical models - using only analytical data - are still the most widely used applications for assessing potential adverse effects and the fate and behavior of chemicals in the environment. Chemical models rely on the assumption that the adverse effect is proportional to the concentration, which in most cases is incorrect. In this volume, other models such as biological and ecological or regression models are discussed in detail and compared. Environmental risk management has two subsections: risk assessment and risk reduction. Environmental risk, to a large extent, arises from the adverse effects of chemicals and contaminated land; that is why measuring and testing these effects plays a key role in risk management. "Environmental Toxicology" deals with direct measurement of adverse effects of pure chemicals or environmental samples. This book has therefore been created specifically for engineers and gives a general overview of environmental toxicology. It provides an overview of hundreds of standardized and nonstandardized, generic and site-specific, conventional and innovative, animal and alternative test methods, and demonstrates how to apply these results to the regulation and management of environmental risk. In addition to human, aquatic and terrestrial methods for measuring toxicity, new trends in environmental analytics and the integration and complementary use of chemical analyses and the testing of effects are described. Bioavailability and accessibility as key parameters are detailed and the interactive and dynamic characterization of contaminants in soil is introduced. Emphasis is placed on the evaluation and interpretation of environmental fate and adverse effect data as well as the simulation of environmental processes and effects in microcosms and mesocosms.

A thorough understanding of cellular and molecular mechanisms involved in the individual expression of toxic effects provides an important tool for assessment of human health risk. New aspects, major advances, and new areas in molecular and cellular biology and toxicology demand updated sources of information to elucidate the functional mechanics of human toxicology.

Mechanistic Toxicology: The Molecular Basis of How Chemicals Disrupt Biological Targets, Second Edition retains the accessible format of the original to present the general principles that link xenobiotic-induced toxicity with the molecular pathways that underlie these toxic effects. Extensively illustrated, this book forms a conceptual bridge between multiple events at the molecular level and the determinants of toxicity at the physiological and cellular level. Specific examples of drugs, environmental pollutants, and other chemicals are carefully chosen to illustrate and highlight the fundamental mechanisms of toxicity at different toxicokinetic and toxicodynamic levels. The book includes references and review articles at the end of each chapter, as well as boxed text for relevant review information on biological, biochemical, molecular, and toxicological background. Linking molecular pathways to more general biomedical contexts, the author ensures that the reader is not lost in the details and instead receives a broad understanding of the processes underlying xenobiotic toxicity.

New in the Second Edition Updated chapters Types of toxic responses Disruption of signal transduction by xenobiotics Disruption of mitochondrial function Novel mechanisms derived from systems toxicology

Plants depend on physiological mechanisms to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezing, salt, UV, intense light, heavy metals and SO2. Many of these cause excess production of active oxygen species in plant cells. Plants have evolved complex defense systems against such oxidative stress. The study of these mechanisms has become a fast-moving, important field to many biologists. Written and edited by world-leading scientists, Oxidative Stress in Plants explores the current knowledge of the mechanisms by which various biotic and abiotic environmental stress conditions produce oxygen radicals. The text considers the biochemistry and molecular biology of both non-enzymatic (vitamin C, glutathione) and enzymatic systems which eliminate active oxygen species. In addition, the book discusses evidence that active oxygen species and antioxidants act as signals which trigger defense reactions.

The use of drugs as remedies for various types of diseases has a long tradition; however, it has only been recently recognized that the value of any given compound must be evaluated in light of its benefit to risk ratio. When prescribing drugs, physicians must look at the big picture of the drug's benefits in relation to its side effects and possible toxicity. The aim of this handbook is to compile data from various authors, providing clinicians with data that will optimize their decision making in selecting effective, low-risk drug treatments. It also provides research workers, including physicians, pharmacists, and basic scientists, with a sound basis for increasing knowledge of the risk/benefit ratios of various drugs. Includes detailed assessments of the following types of drugs: Antihypertensive agents Diuretics Anti-diabetic drugs Anticonvulsant drugs Drugs for Parkinson's disease Antihistamines and antiserotonins Cytokines and immunomodulators Non-opioid analgesics and anti-inflammatory agents Antibacterial agents Antiviral agents Drugs used in reproductive endocrinology Systemic drugs for skin diseases Topical liposome drugs Topical glucocorticoids

Since the discovery of Glutathione S-Transferase (GST) or Glutathione transferase, studies have probed important questions about its pharmacological and physiological significance. Toxicology of Glutathione Transferases is the only text that details the methods used in GST research. With chapters written by experts who have been involved in all areas of GST research and have actively contributed to the progress of this field, the book describes the role of GSTs in toxicology, focusing on their pharmacologic and physiologic roles and their relevance to biological toxicology. The book provides current information on gene families, structure and regulation of gene expression, reaction mechanisms and substrates, three-dimensional structures of GSTs, design of proteins with GST activity, and various approaches to developing inhibitors that overcome drug resistance. It also covers the physiological significance and the mechanisms of activation of microsomal GSTs. carcinogens and possible implications of GST polymorphism in human health and disease, make the volume useful to researchers in the field of pharmacology and toxicology. Chapters cover the possible and exciting role of GSTs in defense mechanisms against chronic oxidative stress-linked disorders such as atherosclerosis and the newly emerging area of GST-mediated modulation of stress-signaling through its catalytic as well as binding activities. They explore an intriguing hypothesis that strongly suggests an important role of the factors that modulate the GSH-electrophile conjugate (GS-E) homeostasis in the regulation of cellular processes. Chapters on known and potential endogenous electrophilic substrates and a major role of GSTs in suppressing stress-induced lipid peroxidation reinforce this newly emerging role of GSTs. These are just a few of the features that make the book helpful to clinicians involved in basic as well as translational research, particularly those studying oxidative stress-related degenerative diseases.

During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.

This book provides a guide to the use and meaning of toxicological and ecological information in the paper industry. For example, the information provided by suppliers of paper chemicals to paper mills is analysed in detail. This allows for greater understanding by users and therefore awareness of the possible implications of handling a given chemical with respect to its impact on the working environment, the final product and the environment beyond the mill. The information currently available is collected, summarised and systematised so that users bombarded with inconsistent Safety Data Sheets can make intelligent use of them or can ask sensible questions of their suppliers. Emphasis is on providing guidance on how to find a commercially realistic path between over evaluation and under evaluation of potential health and environmental risks.

An understanding of the fate and behaviour of organic chemicals, such as surfactants, in the environment is a prerequisite for the sustainable development of human health and ecosystems. As surfactants are being produced in huge amounts, it is important to have a detailed knowledge about their lifetime in the environment, their biodegradability in wastewater treatment plants and in natural waters, and their ecotoxicity. Parameters relevant for the assessment of long-term behaviour, such as interactions with hormonal systems need to be understood to avoid unexpected adverse effects to future generations of people and the environment. However, the identification and quantification of commercial surfactants in the environment is made more complicated and cumbersome because they comprise of tens to hundreds of homologues, oligomers and isomers of anionic, nonionic, cationic and amphoteric compounds.
The EU-funded PRISTINE project (Priority surfactants and their toxic metabolites in wastewater effluents: An integrated study; ENV4-CT97-0494) provides the basis for the content of this title. It provides policy makers and industry with detailed information on analysis and concentrations of surfactants and their degradation products in the environment.
In addition to a general introduction to surfactants, this book comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment. Readers will find all the necessary information for analyzing the different groups of surfactants, with special emphasis on transformation products. Quality assurance is also reported on in detail. Chapters on toxicity and risk assessment are also included and give a complete perspective on the surfactants problem in the aquatic environment.
