The project will investigate the peripheral boundary pollution and the volatile hazardous air pollutant emission characteristic of process stack from 30 specific stationary sources. The results, as well as the previous achievements, and the background information on peripheral control standards from advanced countries, will be complied into complete background information, which serves as the basis of drawing up control standard of the peripheral boundary concentration, and making recommendation for revision for 25 specific volatile hazardous air pollutants. The tasks performed included the investigation of emission characteristic of the peripheral boundary from 31 factories (62 spots), the pollution preventive equipment from 45 specific factories, and the volatile organic compounds emission rate of 150 elements of equipments from 5 petrochemical factories. In addition, we would frame the suggested standard values of peripheral boundary concentration for the 25 specific volatile hazardous air pollutants, and collected the entire information of previous years to establish VOCs emission rate of the equipment components in local petrochemical industry. We also correlated the information of the peripheral boundary for control and strategy from foreign countries and collected domestic and foreign examination methods of peripheral boundary as well. We also collected the control information of emission from restaurant operations in foreign countries. The results assisted to drafting the regulations of the restaurant business, and to suggest the verification of the pollution preventive equipments.
