Plastic debris, microplastics and nanoplastics together forms a plastic waste continuum which is contaminating our environment. What are the effects of these plastics on the ecosystem and human health? Our group aims to answer this question by developing new theoretical concepts and techniques. We bridge the gap between conceptual and empirical approaches in order to gain a mechanistic understanding of the risks of plastic debris to human health and the environment. Our projects span a diverse range such as development of analytical methods, field monitoring, transport and fate modelling, chemical vector effect analysis, toxicity studies, human exposure and risk assessments, food web modelling and many more. We believe that solutions to the plastic problem require collaboration among all stakeholders, and our independent scietific research is therefore available to all interest groups. We also engage actively in science communication and policy advice. With these activities we hope to contribute to achieving a safe and clean environment.
