We chose a petrochemical park in Beijing-Tianjin-Hebei as the research target, and five representative sites were selected for sampling and analysis. 85 volatile organic compounds（VOCs）were detected and their impacts on the environment and health were evaluated. The results showed that the concentration of total volatile organic compounds（TVOCs）were 546.0~4472.2µg/m3, in which alkanes and alkenes were the dominant group, followed by aromatics and halocarbons. Compared with the diurnal variation of VOCs components at each site, the time of peak and valley values appearing were different, and the typical species were different. Additionally, OFP in the synthetic rubber area was the richest（13239.8µg/m3）. The contribution of alkenes to OFP was the highest（62.8%~90.5%）, followed by alkanes（3.8%~34.8%）and aromatics（2.2%~22.1%）. Otherwise, only the synthetic rubber area was polluted by odor, 1,3-butadiene（0.68）and n-hexane（0.30）were the main VOCs species that produced odor. Moreover, the health risk associated with each site was assessed by the US EPA method, indicating that the non-cancer risk of synthetic rubber and cancer risk of oil refining were higher than those of other sites.
