The activities conducted in the laboratory involve measuring the effects of contaminants at the individual level. The objectives are to characterise the biological effects of toxicants on aquatic organisms and to contribute to a better knowledge of biological and physicochemical phenomena that explain these effects.
- The effects of metal mixtures on the base of cytosolic concentrations
- Contamination of fish & the Rhone sediments by PCBs
Tools and technology
- Studies on fish and invertebrates
- Sampling and in situ experiments (caging)
- Bioassays: exposure in static or continuous mode
- Biochemical analysis of fish (EROD enzyme activities, AChE)
- Biostatistics, data analysis, modelling, image analysis
In addition to the analysis facilities of the Lyon Group (chemistry laboratory, EDS laboratory) and in situ sampling (boat, electric fishing equipment) that the team uses, the lab also has equipment for biochemical measurements (electrophoresis, microplate spectrophotometer, microplate spectrofluorimeter). It also has a large breeding and housing facility (continuous feeding, regulation of water quality) for fish and invertebrates.
CHIMOTOX is software that allows the coupling of basic approaches (distribution of energy, scaling, aggregation of variables) and operational approaches (testing pollution scenarios: current and future impact, predictive study of risk, links between ecological approach to bio-indication in the field and laboratory ecotoxicological approach). It is mainly focused on the Chironomus species.
To install CHIMOTOX, copy the "install.bat" and "install.jar" to a specific folder.
Then click on install.bat.
