Challenges in environmental hazard assessment – Demonstrating the absence of effects and predicting toxicity for untested materials

Vortragender: Dr. Magdalena Mair, Research Group Leader Statistical Ecotoxicology, Animal Ecology I, BayCEER, UBT (Homepage)
Do. 04.11.2021 (12:15-13:45)

As a society we want to protect ourselves and our environment from negative impacts caused by pollutants (e.g., microplastic) and toxic substances. Regulatory decisions about the approval or ban of a new substance thus require a careful assessment of its ecotoxicological risk by comparing its hazard (toxicity) to its expected concentration in the environment (exposure).
In my talk I want to highlight two challenges specific to hazard assessment that show how both, decisions on a very basic statistical level and complex predictive modeling approaches can help us draw more reliable conclusions. On a very fundamental basis, I will discuss statistical challenges we face when the goal is to demonstrate the absence of negative side-effects, a prerequisite for the registration of new chemicals in the EU. On a more complex level, I will discuss how we can use in silico methods to approach the difficulty that we can only test a few standard test species in the lab with a limited number of contaminants, but at the same time aim at protecting all potentially exposed organisms in a contaminated environment.
