Short summary
We investigated for the first time the role of Si during secondary formation process of PM2.5. We show the noncorrelation of Si with the secondary aerosol (SA) formation in Beijing, which reveals a new conservative tracer for aerosol chemistry. The SA contribution can be estimated by using Si as a single tracer instead of commonly used multiple chemical tracers. The correlation analysis of SA with the Si isotopic composition of PM2.5 can also reveal the sources of the precursors of SA.
We investigated for the first time the role of Si during secondary formation process of PM2.5....
