On December 10, teachers and students of the Department of Chemistry took part in the university open day STEFANYK OPEN DAY. Applicants had the opportunity to learn about climate change on the planet, in particular, about the impact of greenhouse gas emissions on the global increase in atmospheric air temperature. Information about air monitoring methods used in the European Union was relevant. It is useful to be able to disseminate information about the grant project “Monitoring of environmental objects in the context of European integration”, which is implemented with the support of the EU, and will contribute to improving the environmental awareness of citizens.
