Karin Wiberg

Karin Wiberg
I am full Professor in Environmental Organic Chemistry and the leader of a research team (the POPs group). We study sources, transport, fate and exposure of persistent organic pollutants (POPs, micropollutants) such as highly fluorinated substances (PFASs), pharmaceuticals, PAHs, pesticides and flame retardants.


The POPs-group strives for increased knowledge about environmental pollutants and their effects in aquatic and terrestrial environments. The research also includes treatment techniques for improved water quality and sustainable use of water. We develop early warning methodology and new strategies for identification of previously unknown chemical risks with a focus on drinking and waste water through prioritization methodology and advanced mass spectrometry. Our POPs laboratory is dedicated for trace analysis of micropollutants in the environment.
