11:00-12:00 | Ecosystem health and chemical mixture risk assessment and management
Ecosystems are continuously impacted by various combinations of chemicals. The assessment of the effects of such complex mixtures and the development of adequate policies are still a major challenge. An improved understanding of the joint action of the various types of stressors, in terms of synergistic and antagonistic interactions on biota is necessary. For this purpose, combine mixture chemical determinations on environmental matrices (soil, water, sediment) with ecological evaluations make it possible to evaluate the effects of fluctuating stress intensities and responses at different biological levels (behavioural, genetic, individual and community level). Some recent scientific developments, critical reviews of the data and resulting implications for environmental risk assessment and management will be presented.
