Book Description
Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both F. Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to man, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on Earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older. Wherever people's ingenuity has led them to change the face of nature significantly, it has not escaped them that a number of biological con sequences, often unfavourable, ensue.

Book Description
Does a change, which affects a few biological macro-molecules, some cells, or a few individuals within a population, have any ecological significance that would allow the prediction of deleterious effects at higher levels of biological organization, namely the population, community, and ultimately the ecosystem? With contributions from experts in the field, Ecological Biomarkers: Indicators of Ecotoxicological Effects explores how biomarkers can be used to predict effects farther down the chain. It presents a synthesis of the state of the art in the methodology of biomarkers and its contribution to ecological risk assessment. This book describes the core biomarkers currently used in environmental research concerned with biological monitoring, biomarkers which correspond to the defences developed by living organisms in response to contaminants in their environment, and biomarkers that reveal biological damage resulting from contaminant stressors. It examines the efficacy of lysosomal biomarkers, immunotoxicity effects, behavioral disturbances, energy metabolism impairments, endocrine disruption measures, and genotoxicity as all indicative of probable toxic effects at higher biological levels. It is time to revisit the biological responses most ecologically relevant in the diagnosis of the health status of an aquatic environment well before it becomes unmanageable. Biomarkers provide a real possibility of delivering an easily measured marker at a simple level of biological organization that is predictably linked to a potentially ecologically significant effect at higher levels of biological organization. The text explores the latest knowledge and thinking on how to use biomarkers as tools for the assessment of environmental health and management.

Book Description
Nondestructive Biomarkers in Vertebrates presents an innovative approach for hazard assessment in vertebrates based on nondestructive rather than destructive methods. The book reviews the state of the art and defines the development and validation procedure of this new strategy. Biological materials, such as blood samples, epithelial tissue, eggs, feathers, and feces that can be obtained without stress or damage to the animal are suggested. Certain traditional studies (blood esterases, blood chemistry, mixed function oxidases, porphyrins, DNA damage, and cytological changes) can be performed on these specimens, along with new tests requiring only very small samples. This approach is developed to benefit protected, threatened species whose existence cannot be further jeopardized by the use of destructive methods. This volume will be particularly useful to ecotoxicologists, wildlife protection personnel, environmental consultants, and conservationist organizations.

Book Description
Many areas of Eastern Europe have been polluted to an extent unknown in the West. Four such sites - Kola Peninsula, northern Bohemia, upper Vistula Basin, and Katowice - have been identified and detailed accounts of the pollution at these sites are given. The current status of the use of biomarkers in hazard assessment is given by several scientists from NATO countries. Four working groups, comprising scientists working on the polluted sites and western scientists with expertise in biomarkers, examine the use of biomarkers to assess the environmental health of each of these areas and make recommendations on the future direction of remedial action in these areas.

A variety of human activities, including municipal waste disposal, industrial emissions, military testing, and agricultural practices have left their impacts on soils in the form of elevated, and locally high concentrations of toxicants. In several cases sources have not yet been stopped and contamination continues. Decisions on the management of contaminated sites require information on the extent to which toxicants adversely affect the soil ecosystem. For this purpose, it is often insufficient to extrapolate from abiotic sampling. The detection of a toxicant in the abiotic environment usually does not allow a very strong conclusion on the potential hazards.

Book Description
Biological markers (biomarkers) are useful tools for understanding the nature and extent of human exposure and risk from environmental toxicants. Biomarkers are classified into three basic categories: exposure, effect, or susceptibility. A marker of exposure is the product of the interaction between a target cell or molecule and a foreign substance (NAS, 1989). These markers can be used to determine the biologically effective dose necessary to elicit a particular physiological change in an organism. A marker of effect is a biochemical or physiological change in an organism that can predict the onset of adverse health effects resulting from a given exposure. Lastly, markers of susceptibility act as indicators of an inherent or acquired tendency of an organism to experience an adverse health effect (NAS, 1989). These markers are already used to detect a variety of diseases and show great promise for developing a better understanding of the mechanicisms of disease. Additionally, biomarkers can be used to establish a more rational basis for quantitative risk extrapolation between species, as weIl as to obtain more precise estimates of the time of critical exposure. These markers can also prove helpful in identifying potentially damaging exposures before the onset of adverse health effects. Biomarkers serve as a valuable exposure assessment tool because they take into account exposure from all routes and integrate exposure from all sources. They have the potential to yield better risk estimates than current monitoring and modeling protocols. In lune 1992, Dr. Travis and Dr.
