Assessment of risks to ecosystems

Analysis of the biological environment and of sensitive or representative organisms (Natura2000 sites, wetlands, sites of special biological interest, etc.)
Identification of the interactions between these organisms, the medium in which they live and ambient pollution (development of a “site conceptual model”)
Modelling of the transfer of pollutants from the medium to the living organisms in question, taking into account the specifics of their exposure
Qualitative and quantitative assessment of the exposure of organisms to pollution of the soil, water, air, sediments (calculation of “exposure doses”)
Assessment of the risks which may result from such exposure by comparison with reference ecotoxicological values (calculation “of risk indices”)
Estimate of the Potentially Affected Fractions (PAF) of microorganisms, invertebrates and vegetation
Interpretation of biotest results
Research on and development of reference ecotoxicological values for all pollutants
