Small-scale Freshwater Toxicity Investigations: 1 Small-scale Freshwater Toxicity Investigations

Assessment). Dr. Blaise has (co)authored over 100 scientific articles in internationally refereed journals, as well as having written several book chapters, reviews, and various government technical reports.

He recently co-edited, with Canadian colleagues, a book dedicated to small-scale toxicity testing (Wells, P., K. Lee and C. Blaise (eds.), 1998. Microscale testing in Aquatic Toxicology Advances, Techniques and Practice. CRC Lewis Publishers, Boca Raton, Florida, 679 pages). He was scientific organizer of the 10th International Symposium on Toxicity Assessment (ISTA 10), hosted by the Saint-Lawrence Centre where he works, and held in Quebec City, August 26-31, 2001. He further co-edited with another Canadian colleague, a special edition of Environ. Toxicol. (Volume 17 [3]: 2002, special issue) highlighting selected papers presented at the ISTA 10 venue.

Jean-François Férard, D.Sc., is a professor at the University of Metz (Lorraine province of France), where he heads a research team (RT) which is part of a C.N.R.S. (Centre National de la Recherche Scientifique) research unit for Ecotoxicity and Environmental Health (E.S.E). He also manages an undergraduate school program dedicated to Environmental Engineering. His teaching duties involve fundamental and applied Ecotoxicology, Physiology and Physiotoxicology, Cell Biology and other related disciplines.

In the field of ecotoxicology, his RT was involved in the behavior of metals, PAHs and complex mixtures in air, water and soil compartments and their effects on different organisms (bacteria, algae, crustaceans, plants, arthropods, etc.). His actual research endeavors are more specifically focused on the development of metal-resistance (e.g. phytochelatin) and genotoxic (e.g. comet assay) biomarkers. He also promotes knowledge and use of toxicity tests by organizing an annual course entitled "Ecotoxicity and carcinogenicity of chemicals" which provides a theoretical and practical view of numerous toxicity tests to decision-makers, industrialists and consultants. Since 1974, he has markedly contributed to numerous research programs that have successfully lead to i) development and validation of different ecotoxicity tools (e.g. new toxicity test methods, trophic chain models, biomarkers), ii) hazard/risk assessment schemes and iii) links between field and laboratory studies. These undertakings were financially supported by the European Economic Community, the French ministry of the Environment, and agencies such as the French Water Agency of the Rhin-Meuse Watershed, the French Agency for Environment and Energy Ressources.

Professor Férard obtained university diplomas from the U. of Strasbourg (B.A., 1970: biology and chemistry; B.Sc., 1973: biochemistry) and U. of Metz (M.Sc., 1974: chemistry and environmental toxicology; D.Sc., 1978: environmental toxicology; State doctorate, 1986: environmental toxicology). He was European editor for Environmental Toxicology and Water Quality from 1992-1996 and holds membership in SETAC (Society of Environmental Toxicology and Chemistry). He regularly makes presentations during major symposia held in the field of ecotoxicology (e.g. SETAC meetings, Secotox conferences, International Symposia on Toxicity Assessment, Annual Aquatic Toxicity Workshops in Canada). Professor Férard has (co)authored over 50 scientific articles in (inter)nationally refereed journals, as well as having written several book chapters, reviews, and research reports. He also participates in several OECD (Organization for Economic Cooperation and Development) and AFNOR (Association française de normalisation - French standards association) initiatives to standardize and promote the use of biological tests.

able to provide comprehensive information on biological testing as well regarding theory and concepts as regarding toxicity testing applications. For academia, governmental authorities and consulting people the two volumes are of interest and helpful. One can state that these two volumes are "state of the art" and are an important contribution to the field of freshwater ecotoxicology". Prof..Dr. rer.nat. Dr. h.c. A. Kettrup, Technische Universität MünchenEnvironmental contamination is a world-wide problem, which is of increasing concern with the rapid industrialization of nations which are moving out of the less-developed nation status. Many industrial products formerly made in highly developed nations, are now being made offshore and imported, leaving the environmental impacts of their production to nations with less sophisticated procedures for environmental monitoring. The advantage of small-scale biotests for toxicity assessment is the simplicity of equipment requirements and the lesser need for advanced technical training to carry out the tests. This approach to pollution monitoring is therefore highly relevant to the emerging industrialized nations. Biotests however continue to remain relevant to highly developed nations, due to the complex mixtures of pollutants generated by industrial processes, which are not totally amenable to assessment by analytical chemistry.Volume 1 describes, in sufficient detail for the methodology to be followed in an environmental pollution laboratory, use of bacteria, algae, macrophytes, protozoa, small invertebrates and fish cells in toxicity testing. The volumes both commence with an overview of the application of small scale biotests to effluents, with extensive referencing. It is of interest to note that the most-used toxicity tests employ small invertebrates such as Daphnia species which can be obtained from wild populations, thus reducing the costs of tests. One of the points made in this volume is the different responses of organisms at different trophic levels to pollutants, necessitating use of a range of organisms in testing of any pollutant. Volume 2 demonstrates the integration of a battery of toxicity tests in the hazard assessment of pollutants. One of the issues that arises from the differential sensitivity of organisms to pollutants is the approach to be used when applying disparate results in a composite hazard assessment. In this volume several different approaches are described, aimed at providing an overall toxicity measure that is intelligible to regulators. Methodologies developed in Canada, France, Germany and South America are described, using different approaches. The volume concludes with methodologies for toxicity assessment in solid wastes and sediments.Both volumes will be of practical use to practitioners in pollution monitoring and hazard assessment, and can be recommended.
