Short summary

We compared the differences in concentrations of oxalic acid and related SOA and the stable carbon isotopic compositions of oxalic acid Beijing before, during and after the APEC 2014 conference, to investigate the impact of pollutant emission controls on the origins and formation mechanisms of PM_2.5. Our results indicate that the significant reduction in PM_2.5 during APEC is firstly due to the emission control and secondly attributed to the relatively colder and drier conditions.
