The international conference SETAC (Society of Environmental Toxicology and Chemistry) took place in Copenhagen (Denmark) from 15 to 19 May 2022. The conference was attended by more than 1,500 presenters, mainly from Europe. One research topic connected all participants: the pollution of aquatic and terrestrial ecosystems by emergent pollutants, including pesticides, drugs, microplastics and other persistent substances and their metabolites. For example, an exciting topic was how to effectively reduce the dispersion of plastics into the environment by applying the theory of "Upstream Innovation" to the circular economy. The use of invertebrates in ecotoxicology was a thematic track in which I presented a poster entitled "Integrated biomarker response in signal crayfish Pacifastacus leniusculus exposed to diphenhydramine".
