Synopsis

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.

About this title

Synopsis:

One of the most difficult decisions facing those responsible for the enforcement of environmental regulations and laws is how much clean-up is necessary. A decision to do too little may cause irreversible damage to the environment, while a decision to do more than is necessary may waste resources better spent elsewhere. Using an approach similar to clinical biochemistry in human medicine, this book is a critical examination of the use of biomarkers (the physiological or biochemical changes caused by chemicals) to indicate the state of health of wildlife in the environment. Because of the increasing concern over the effects of toxic chemicals on the biosphere, the choice of reliable indicators to measure the effect of them in animals is therefore absolutely crucial. David Peakall has been involved in researching biomarkers for many years and has been active in a number of international advisory bodies dealing with pollution problems. His book looks at the range of biomarkers, their usefulness in monitoring pollution and the prediction of the biotoxic effects of the release of toxic chemicals.

He concludes that basing decisions on the physiological function of organisms, using the biomarkers and the concept of "exclusion zones", is a more rational and successful approach to pollution problems compared with the classical toxicological approach of setting pollution "levels".
