EcotoxicologieEcologie (ERE)

Master: • Assessment of the effects of products and substances on wildlife and the environment: environmental metrology, modelling of pollution and its transfer within environments, metrology of system and ecosystem exposures, toxicity of substances to ecosystems and humans at low levels of exposure. • And provide elements of description: monographic studies on environments, rivers and soils and ecosystem analysis to quantify the degree of pollution

Objectives of the course – General organisation of the module

History – Definitions: ecology, ecotoxicology Toxicology, pollution, ecosystems, biotope, biocenosis...

Fundamental ecology. • Environments: atmosphere (some notions of atmospheric dispersion modelling), soil (texture, structure, porosity, soil water), tablecloth, rivers ... • Stands: plants (soil/plant relationship), animals • Biodiversity • Biogeochemical cycles

TD #1: Knowledge of the ecotoxicology of chemicals and their behaviour in the environment by searching for key information on national and international databases (essential Internet access)

Applied ecology. • Risk assessment: why, how, different methods • The different steps of a risk calculation: the fate of pollutants in the environmental compartments, bioaccumulation, the effects of pollutants on the environment, exposure, the dose-effect relationship • Reference values in impact studies • Limitations of interpretation, uncertainties

TD #2: Setting: Dispersion/transfer/impact calculations used in impact studies (calculator or EXCEL required)

• Additional TD on public databases of reference values in media (so-called Background Noise)

Ecotoxicology methodology. • Bio-tests • Environmental monitoring: sampling plan, laboratory analyses, interpretation of results • Bio-indicators, index methods

TD #3: Case study: development of a monitoring plan for environments around an industrial installation

TD #4: Knowledge of standardized ecotoxicology tests

If remaining time: introduction to molecular ecotoxicology (barcoding, reference banks ...)
