Chapter 1 presented an overview of the science of ecotoxicology. Chapters 2 through 10 discussed a range of autecotoxicological issues including biomolecular to whole organism issues. Particularly relevant points are summarized in the paragraphs below. SOME PARTICULARLY KEY CONCEPTS Ecotoxicology is the science of contaminants in the biosphere and their effects on constituents of the biosphere including humans. It is a hierarchical science in which no level in the biological hierarchy is superior to another in the context of identifying causation or attributing relevance. Accordingly the modified Janus context was advocated for optimal inference and organization of knowledge around paradigms at all levels of biological organization. Two factors were described as most needed in ecotoxicology at the moment the application of the strongest possible inferences for the purpose of efficiently organizing knowledge around rigorously tested paradigms and the consilience of concepts and paradigms among all hierarchical levels. The advantages of an autecological exploration of ecotoxicology were outlined in Chapter 2. They include the rapid transfer of new technologies from mammalian toxicology into ecotoxicology provision of mechanistic understanding for effects seen at higher levels of organization provision of sensitive indicators of exposure or effect and creation of a highly discrete and tractable approach to any ecotoxicological questions. Careful interpretation of organismal data improves our ability to predict consequences at the population and commonly community levels of organization. Also models of bioaccumulation in individuals set the stage for models predicting trophic transfer of toxicants in food webs. Biochemical issues relevant to ecotoxicology were outlined in Chapter 3.
