VOCs Emission Characteristics of a Medical and Chemical Park Based on Navigation Monitoring
With the acceleration of industrialization,the emission of volatile organic compounds(volatile organic compounds,VOCs)has increasingly become one of the important sources of air pollution.As an important production and pharmaceutical base,VOCs emission management needs to be strengthened.In this study,SPIMS-2000 was monitored from July 2021 to December 2021,and analyzed the change of VOCs concentration in different regions and different periods.The results show that the TVOCs concentration in H medical park is significantly higher than that in the main urban area,the main urban area is relatively clean,and the VOCs pollution is concentrated in H medical park.The unusually high value points were counted,and the important substances were identified.The results show that the southern area of Q Chemical Park is clean,the TVOCs concentration is 3 349 μg/m3,and the main component is toluene,discharged from Q chemical plant.The main pollutant in the south bank of J Pharmaceutical is xylene,which is mainly affected by the solvent volatilization in the decoration paint spraying process of J Pharmaceutical plant,and belongs to the unorganized emission.In general,the VOCs emission of H medical chemical park has little impact on the main urban area of T City.
