Abstract Since it is difficult to measure BAP unorganized emissions directly from coke ovens, a large uncertainty exists in related studies. So with the observation data and production capacity of a coke plant in Shanghai from 1999 to 2003, we used an inverse model based on AERMOD (AMS/EPA REGULATORY MODEL) to estimate the BAP emission factor. The results show that annual concentration of three monitoring stations near this plant are 0.033,0.0024,0.0031μg/m3, all exceeded the standard. The unorganized emission factor from this study was 14.71mg/tcoke, The area where BAP concentration exceeded the standard was 125km2 surrounding the coke plant and the atmospheric environment protection zone should be set to 6300m.
