As the bases of ecotoxicology lie in the analysis of the structure and the functioning of natural systems, the first two chapters of this Volume I, Part I, are devoted to a synthesis of the current state of knowledge in relation to two main types of freshwater ecosystems: running water (rivers) and still water (lakes). The main concepts of ecotoxicology are developed giving particular emphasis to the mechanisms which bring the transfer of contaminants between the different compartments, and also the effects this produces at each biological integration level. The problems of contaminant quantification, from the collecting of samples to the different dosing methods, are described using trace metals and metalloids as examples. The other three chapters in Part II deal with the evolution of pollutants in aquatic biotopes: chemical speciation of trace metals adsorption of trace inorganic and organic contaminants by solid particulate matter and geochemistry and bioavailability of trace metals in sediments. The most significant research methodologies currently being developed in aquatic ecotoxicology are presented in Part III. After describing the essential mechanisms of contamination of the hydrosphere and its effects on ecosystems, three case studies were selected to illustrate particular features of field research, the methodologies used and the type of results produced. In an intermediate position between the ecosystems level and laboratory models are enclosures and artificial streams. Separate abstracts are included for 13 chapters in this book for inclusion in the appropriate data bases.
