The modules for simulating transport, transformation and deposition processes, as well as gas/particle partitioning (KOA absorption mechanism) processes of atmospheric BaP was implemented into the CMAQ, a regional air quality model developed by U.S. E.P.A. The spatial distributions of BaP concentrations, dry and wet deposition rates are simulated for January, April, July and October 2014 in China. The comparison between modeled and observed BaP concentrations shows the predicted values were in an acceptable range. The predicted deposition results show that the wet deposition is the dominant deposition pathway. The spatial distributions of the BaP depositions are closely related to that of the anthropogenic emissions and present obvious long-distance transportation characteristics.
