Reconciling standard procedures and environmental realism in ecotoxicology: conceptual and practical challenges

Abstract : Ecotoxicology makes large use of standardized procedures to collect reliable data on the possible effects of chemicals on biota. These data can serve both scientific and regulatory purposes. However, standardized procedures make several assumptions that limit their actual relevance to real field situations. The project proposed in this HDR dissertation critically reviews such assumptions to derive recommendations for future research on how to reconcile the reliability of standardized procedures with environmental realisms. The proposed recommendations are discussed in relation to five broad scientific research areas: the choice of the most appropriate metrics of exposure and response, the importance of the time factor in controlling biological responses, the effects of chemicals’ mixtures, the role of matrix effects and routes of exposure, and broad-scale issues related to climate change and river-to-sea continuum. Personal considerations as to the risks of bias in ecotoxicology and its link with the functioning of the current research industry (i.e., the management of research based on quantitative indicators) are also offered for a critical discussion.
