Abstract: In August 2018, air samples were collected in Taiyuan. The pollution characteristics of ambient volatile organic compounds (VOCs) were analyzed and the ozone formation potential (OFP) of VOCs was also calculated by the maximum incremental reactivity (MIR). The results showed that the VOCs concentration in summer ranged from 17.36μg/m3 to 89.60μg/m3. And the average proportions of alkanes, aromatics, alkenes, alkynes were 58.01%, 20.06%, 16.52%, 5.40%, respectively. The diurnal variations of VOCs concentrations showed obvious bimodal distribution in the morning and evening, and the influence of morning peaks was more significant. Alkanes, alkenes, aromatics and alkynes contributed 19.16%, 47.74%, 31.75% and 1.35% to the total OFP, respectively. C3~C5 alkenes have high activity, which greatly contribute to O3 formation.
