In this study, volatile organic compounds (VOCs) released from chemical synthesis pharmaceutical industry in Taizhou, Zhejiang province were analyzed quantitatively and qualitatively. The total volatile organic compounds (TVOCs) was in the range of 14.9-308.6 mg·m-3. Evaluation models of ozone formation potentials (OFP) and health risk assessment were adopted to preliminarily assess the environmental impact and health risk of VOCs. The results showed that the values of OFP of VOCs were in the range of 3.1-315.1 mg·m-3, based on the maximum incremental reactivity, the main principal contribution was toluene, tetrahydrofuran (THF), acetic ether etc. The non-carcinogenic risk and the carcinogen risk fell in the ranges of 9.48×10-7-4.98×10-4 a-1 and 3.17×10-5-6.33×10-3. The principal contribution of VOCs was benzene, formaldehyde and methylene chloride. Source

Based on Zhejiang province, the main source and characteristics of volatile organic compounds (VOCs) released from pharmaceutical industry was analyzed quantitatively and qualitatively in this paper, using Gas Chromatography (GC). Sixteen components including methanol, acetone, benzene respectively, toluene, xylene, dichloromethane, ethyl acetate, three ethylamine, DMF, butyl acetate, propyl alcohol, isopropanol, ethanol, acetonitrile, ethylene oxide and formaldehyde was identified. The type of pollutant was correlated to the type of pharmaceutical process, such as fermentation, extraction, bioengineering and chemical synthesis. Results indicated that the main VOCs from various pharmaceutical process are as follows: acetone (65%) and ethyl acetate (30.41%) for fermentation; acetone (56.05%), ethyl acetate (36.64%) and ethanol (6.97%) for extraction. Isopropyl alcohol (44.27%), acetone (35.39%), ethanol (9.78%) and toluene (3.89%) for chemical synthesis. Acetone (60.99%), methylene chloride (14.77%), ethanol (12%) formaldehyde (11.91%) and for bioengineering. And the above main VOCs were sorted by their control priority. Finally, by referencing characteristics in pharmaceutical industry, effective methods to control the emission of VOCs are put forward. Source
