Démarche optimale de sélection de batterie de bioessais pour l'évaluation écotoxicologique des milieux complexes. Synthèse bibliographique

Abstract : The use of a combination of biological tests (or battery) is now recognized to be relevant for characterizing the environment quality, in addition to chemical analyses. Thus, within the framework of this study, launched by Ademe, the selection of relevant bibliography was carried out in order to establish an inventory of the existing batteries of tests as well as an assessment of the possible statistical treatments used. Generally, two methods are mentioned to select the biological tests constitutive of a battery: a method a priori based on predefined criteria and, a method a posteriori based on results obtained on a broad series of samples. The majority of reviews deal with a posteriori selection. It also appears that the proposed test batteries are not dedicated to a particular application but, are used to evaluate the toxicity of the samples and/or to compare tests between them. As regards the statistical method found in the literature, it appears that these tools are often badly or under-employed. Commonly, the authors propose a posteriori step based on the application of a Principal Component Analysis (PCA) to determine the choice of the tests in the battery. Finally, an optimal framework including five steps was proposed for designing a battery of tests. This framework was not observed in the literature and should be studied more thoroughly in the future. In conclusion, this bibliographical review showed that few authors argue their choices concerning the development of the test batteries. Concerning the use of the batteries, it appeared that they are not dedicated to some scenarii such as agricultural valorisation. In addition, it is interesting to note that half of the selected batteries integrate a double approach direct and indirect.
