原始语种摘要: Abstract(#br)This study provided an insight into the complex phenomenon of acid deposition over Dhaka division of Bangladesh. The 10– day HYSPLIT back trajectories showed that majority of air masses arriving to Bangladesh were originated from the west. The gridded emissions (0.055° or ~5.5km) for Dhaka division was prepared for 2006 by updating a preliminary emission inventory (EI) available for 2000 and by conducting a new EI for two major source categories, brick kilns and traffic. In Dhaka division as of 2006, the brick kilns contributed the largest SO 2 emission (about 70%), while residential emissions had the highest share of CO and PM 10 (over 60%) and substantial NMVOC (about 40%). Emission rates of SO 2 and NO x in the dry season of 355t/d and...
