The pharmaceutical industry has attracted much concern due to its large use of organic solvents and emission of VOCs (volatile organic compounds).In this study,107 VOCs species from 3 kinds of pharmaceutical enterprises including chemical synthesis,biological fermentation,and traditional Chinese medicine are measured.The results showed that the total VOCs concentration was more than 20 mg/m³ for chemical synthesis and biological fermentation pharmaceutical enterprises,and was relatively small to be 902.66 μg/m³ for traditional Chinese medicine enterprise.Among the 107 VOCs species,the OVOCs (oxygenated volatile organic compounds) were dominant,which accounted for more than 75% of the VOCs discharged by pharmaceutical enterprises.Besides that,the proportion of halogenated hydrocarbon species was high for chemical synthesis pharmacy.Pharmaceutical methods,production process,collection and emission measures are important factors affecting VOCs composition.
