Short summary
Atmospheric airborne mercury is of particular concern because, once inhaled, both Hg and its vectors might have adverse effects on human beings. In this study, we attempted to identify the sources of PM2.5-Hg in Beijing, China, using Hg isotopic composition. Large range and seasonal variations in both mass-dependent and mass-independent fractionations of Hg isotopes in haze particles demonstrate the usefulness of Hg isotopes for directly tracing the sources and its vectors in the atmosphere.
