Abstract
Monitoring of ambient volatile organic compounds (VOCs) was conducted within typical residential-commercial area in the city of Xi'an in northwest China during typical ozone (O3) episodes, to investigate the major contributors to the characteristic of ambient VOCs and their impact on O3 production. In the residential-commercial area, diurnal variation of VOCs was highly impacted by vehicle exhaust, fuel evaporation, and local solvent use. Relative higher contributions (up to 60%) of VOCs from solvent use to the ozone formation potential were found. The present findings highlight the urgent need for restrictions on the emission of VOCs from solvent use and non-vehicle-traffic-related sources, such as oil storage.
