Impacts of vehicle emission on air quality and human health in China

The growing of vehicle population aggravates air pollution and threatens human health. In this study, based on the refined whole-process vehicle emission inventory considering volatile organic compounds (VOCs) evaporation emission, the CAMx model was applied to comprehensively quantify the impacts of the vehicle sector on the annual and seasonal concentrations of PM₂.₅ and O₃ in China. Also, the health risks caused by long-term exposure to PM₂.₅ and O₃ were evaluated. The model results showed that vehicle emission was an important source of severe O₃ pollution in summer, with a contribution of more than 30% in most parts of China, but not an important source of serious PM₂.₅ pollution in winter, with a contribution of less than 20% in heavily polluted regions in China. Compared to tailpipe emission, vehicle VOCs evaporation emission led to increases of 25% and 47% to sectoral contribution to PM₂.₅ and O₃. Health risk assessment results showed that attributable deaths caused by long-term exposure to PM₂.₅ and O₃ were 975,029 and 46,043 in 2018, to which vehicle emission contributed approximately 12.5% and 22.2%, respectively.
