The focus of this report is upon information essential to the understanding of the toxic action of cadmium and the relationship between dose (exposure) and effects on human beings and animals. The therapy of cadmium poisoning has not been discussed.This review on cadmium in the environment has been performed under a contract between the U.S. Environmental Protection Agency and the Department of Environmental Hygiene of the Karolinska Institute, Sweden. The report is intended to serve as a background paper for a future Air Quality Criteria document on cadmium. Therefore, particular attention has been given to information relevant for the evaluation of risks due to long-term exposure to low concentrations of cadmium. Acute effects from short-term exposure to high concentrations are dealt with briefly. In vitro studies without bearing on the main problem have not been dealt with.The report is not limited to effects from exposure via inhalation. Newly accessible information, showing that large populations may be exposed considerably via the oral route, can elucidate chronic effects of cadmium in general. Man and animals can be victims of secondary exposure through vehicles such as food and water which have been contaminated by cadmium in air.

Ecotoxicology of Metals in Invertebrates reviews the state of the art in research concerning metal exposure of marine, freshwater, and terrestrial invertebrates. The book focuses on the uptake and accumulation of essential and non-essential trace metals by invertebrates, metal detoxification and involved mechanisms, adaptations to metal stress, metal regulation and elimination, distribution and speciation of metals in different organs and tissues, and interaction of metals with biotic and abiotic factors. Toxicological studies involve histopathological, electron microscopic, physiological, and biochemical methods. The book emphasizes the ecological and ecotoxicological implications that can be derived from metal exposure of invertebrates in the field. The significance of background concentrations, the evaluation of critical concentrations, and the establishment of environmental quality criteria are discussed as well. Ecotoxicology of Metals in Invertebrates is an excellent reference for ecologists, ecotoxicologists, environmental scientists, ecophysiologists, and students.

Since 1980 there has been an accumulation of new information concerning DNA-damage-inducible processes in eukaryotic cells. It is clear that changes in the concentrations of activities of specific protein molecules play central roles in toxicological response of cells to chemical and radiation damage to DNA. Identification of inducible proteins may be crucial in helping to explain target organ toxicity and species differences. Detection of these proteins or their mRNA's in humans may be useful in assessing human exposure or cellular injury.

The clinical approaches to the chronic degenerative diseases that drain our resources, and compromise our well-being, have become almost exclusively symptom-focused. The common wisdom is that they are idiopathic with final outcomes to be managed rather than prevented or cured. That they are potentially reversible rarely enters any discussion between doctor and patient. Reversibility of Chronic Disease and Hypersensitivity, Volume 5: Treatment Options of Chemical Sensitivity, the final volume of this set, offers a much different perspective on chronic degenerative disease; one that disputes the idiopathic label attached to most, as well as the usual fatalistic prognosis.

As one of many tasks of an analytical chemistry program sponsored by the office of Pesticides and Toxic Substances, Field Studies Branch, U.S. Environmental Protection Agency (EPA) (EPA Prime Contract No. 68-02-3938), Midwest Research Institute (MRI) prepared these summaries of the mammalian toxicology of 52 individual elements (metals and metalloids) and the lanthanides (rare earth elements). MRI is assisting the EPA in developing protocols for the monitoring of selected metals and organic compounds in the blood of the general U.S. population. The monitoring will enable evaluation of changes in the blood levels over time and any trends associated with instituted control measures. This review will help EPA select the metals to be included in the monitoring effort based on toxicity, relative exposure, and the ability of blood measurements to reflect exposure.

The present work is the first major attempt at reviewing comprehensively all the available information about the environmental fate and behaviour of the xenobiotic chemicals.

If we will ever achieve Paul Ehrlich's "magic bullet," that is, a molecule which goes with high selectivity to the therapeutic target site, does what it needs to do, and is subsequently cleared from the body, the practice of safety assessment will have to change. Nonclinical Drug Administration: Formulations, Routes and Regimens for Solving Drug Delivery Problems in Animal Model Systems seeks to address a trio of objectives that, though separate, are linked and central to biomedical science and, ultimately, medicine. Rather seeing these as separate "silos," those working in nonclinical safety assessment will have to view these three in an integrated manner and to regularly and thoughtfully incorporate new information and technology. The trio of objectives this book explores are: first, to present how to deliver more of a drug product systemically to facilitate the regulatory need for evaluating safety and efficacy in animal species (at elevated exposure levels) prior to advancing the drug to human testing; second is to achieve better tolerance to therapeutics administration in test animals and humans which achieves objectives 1 and 3; and third, to explore ways to improve on therapeutic target receptor delivery performance, therefore improving both clinical pharmacodynamics bioavailability and specificity. The book's ten chapters assemble the basic concepts, principles and hypotheses involved in quantitative receptor and chronological organism interaction dynamics central to the successful development of new therapeutics which depend on systemic administration to achieve desired therapeutic goals and in so doing avoid outcomes which limit, marginalize, or preclude the therapeutic use of so many molecules.

Harmful algal blooms (HABs) occurring in freshwater, and the associated toxins they produce, are dangerous to animals and humans. Mitigating the increasing presence of HABs presents a major challenge to water managers and drinking water utilities across the world. This book explores the current research on removal of HABs and toxins from drinking water. It provides the necessary tools so that treatment plant operators, engineers, and water managers can understand the vulnerability of drinking water treatment plants to HABs and develop treatment processes to minimize the impact of these contaminants. Although conventional treatment processes can be effective for the removal of HAB cells and some HAB toxins under optimal conditions, the potential exists for significant breakthrough of toxins during normal operation. As a result, there is a recognized need for more advanced techniques. Possible advanced processes for removing HAB toxins include granular activated carbon (GAC), powdered activated carbon (PAC), or oxidative processes. This book reviews both conventional and advanced treatment processes and presents clear and easy-to-understand procedures for the design of systems for optimal cell or toxin removal.

Leading international scientists share their expertise in aquatic exposure assessment, aquatic ecotoxicology, and the risk assessment and management of plant protection products. The book incorporates the tools and approaches currently available for assessing the environmental risks of time-variable exposure profiles of pesticides. It also discusses the science behind these techniques. This volume covers the extrapolation techniques, including models that address the environmental fate, toxicokinetics, toxicodynamics, and ecological effects, for performing accurate aquatic environmental risk assessments of pesticides. It explains how to link aquatic exposure and effects in the risk assessment procedure for plant protection products.

A prevalent and increasingly important issue, arsenic removal continues to be one of the most important areas of water treatment. Conventional treatment plants may employ several methods for removing arsenic from water. Commonly used processes include oxidation, sedimentation, coagulation and filtration, lime treatment, adsorption onto sorptive media, ion exchange, and membrane filtration. However, in the most affected regions, large conventional treatment plants may not be appropriate and factors such as cost and acceptability as well as performance must be considered. This book, published in cooperation with leading experts in this field, provides a thorough analysis of the problems, solutions, and possible alternatives to achieve safe water production on a global scale.

This textbook presents a comprehensive examination of environmental science and ecotoxicology for undergraduate students. The material provides sufficient related background information leading to a competency to clearly understand ecotoxicology concepts and topics.

This is the final volume in a three-volume work that has addressed the scientific methodologies relevant to clinical neurobehavioral toxicology. Volume I focused on basic concepts and methodologies in Neurobehavioral Toxicology, with Volume II focusing on the peripheral nervous system. Volume III attends to what is known about industrial and environmental chemicals, medicines, and substances of abuse and how these agents affect the central nervous system. All substances have the capacity to be toxic, depending on factors that include the physical properties of the chemical or compound, organism related variables, or interaction between the two. These substances on the other hand and as a result of these same factors might be used therapeutically or even recreationally. The difference between medicine, recreational drug, or poison depends often on a careful balance between adverse and intended effects. How to determine that a specified substance has caused harm is emphasized in the present volume by way of case examples and discussion. Illnesses and behavioral variations that compete with toxicant-induced explanations for findings in a given case, as well as the various controversies that can arise around issues of diagnosis and causal determination, are treated comprehensively in this volume.
