To remove toxic pollutants from air, it’s important to know where they come from. But pinpointing the sources of air pollution is often a challenge. Researchers led by the Paul Scherrer Institute are using a new type of tool to solve this problem. It’s called a mobile aerosol mass spectrometer. It can analyze the surrounding air and identify the types and origin of pollutants.
