Serious fine particulate matter (PM 2.5 ) pollution and rapidly increasing of ground-level ozone (O 3 ) concentrations are concern issues in China. To achieve the comprehensive control of PM 2.5 O 3 composite airpollution, exploring the common sources of PM 2.5 and VOCs is essential. However, previous researches most carried out either PM 2.5 or VOCs source appointment. In this study, we applied the ensemble source apportionment method to explore the impacts of common sources on PM 2.5 -VOCs. Subsequently, we obtained the ensemble source impacts on O 3 combining the extracted VOCs source profile and ozone formation potential. We found that the focus of environmental management and source control should be varied accordingly for different pollutants. Vehicle emission was the largest contributor (41 %) to PM 2.5 -VOCs, while industrial emission was the main common source (51 %) to O 3 . The result showed that the O 3 production rate is not only related to the VOCs emission, but also to the reactivity of VOCs. In addition, sensitivity tests revealed that temperature was the main factor affecting O 3 formation. The study provides a framework to explore the common sources impact on PM 2.5 and VOCs, which is benefit to address both PM 2.5 and O 3 mitigations.
