Discussion on Sampling Technology of Air Pollution Sources Monitoring

SU Fumin1,GAO Xiang2,WANG Tongjian2(1. Tianjin Nankai Environmental Monitoring Station, Tianjin300113,China2. Tianjin Environmental Monitoring Center, Tianjin300191,China)  
In this paper, with the reference to the velocity of discharge, the average emission concentration and the emission characteristics of the gaseous pollution sources, three sampling methods: integral method, integration by parts and finite summation approximation are derived, which are employed in monitoring of pollution sources. On the basis of analytical chemistry, the design method of the sampling time is provided. Therefore the monitoring method and the sampling frequency of different kinds of emission sources are laid out.
