Short summary
Perfluoroalkyl acid (PFAA) pollution is a hot issue globally. It has severe toxicity and exists ubiquitously in the environment. China produces and uses a large quantity, becoming an emerging contamination hotspot in the world. Understanding their extract sources would be of great benefit to management of PFAAs. This article provides the first research on atmospheric PFAAs in China, successfully identifying four major potential factors affecting PFAA variations via a PMF model.
