We use our expertise in environmental trace analytics, experimental environmental chemistry and ecotoxicology as well as the modelling of the fate and effects of substances to analyse their risks in the environment. In consultation with the regulatory authorities, we identify issues and develop test guidelines to address them. We are partners to industry for the quality-assured implementation and evaluation of complex experimental and model-based studies with scientific standards and fulfil the relevant requirements of the ECHA (REACH) or EMA. We use the analysis and classification of molecular mechanisms of action in screening tools for environmental effects of product candidates. We host the Federal Environmental Specimen Bank and carry out environmental monitoring projects in order to identify potential new environmental impacts and verify prospective assessments.
