Anja goes on a lab tour with Alexandra ter Halle from Paul Sabatier University in Toulouse. The chemist and her team were the first to detect nanoplastic in the open ocean - plastic so small that it is comparable in size to a virus. What do we know about these very tiny pieces, and how do researchers try to detect and understand them?

The Plastisphere is a research and interview podcast by German freelance journalist Anja Krieger.
