| The problem was discussed on “Integrated emission standards of air pollutants” (GB 16297-1996) in practical application, used in China to control exhaust gas emission of vehicle repair and maintenance company. In this standard, the controlled environmental factor didn't contain the main pollution agents of exhaust gas emission, without controlling the emission of Total Volatile Organic Compounds (TVOC) which would affect atmospheric environment quality. Based on "Technical methods for making local emission standards of air pollutants" (GB/T 3840-1991), "Occupational Exposure Limit for Hazardous Agents in the Workplace" (GBZ 2.1-2007), "Hygienic Standards for the Design of Industrial Enterprises" (TJ 36-1979), and USEPA multilayered medium environmental model, the study calculated the limit value of emission concentration and emission rate of several volatile organic substances of exhaust gas discharged by vehicle repair and maintenance company with different methods. The data was analyzed to make suggestion on drafting standard for exhaust gas emission of vehicle repair and maintenance company. |
