The Emission, Transport and Deposition of Aeolian Ammonia From Poultry Farm to Pumicestone Passage: Use of TAPM to Estimate Annual Loading

The Air Pollution Model (TAPM) was used to investigate the transport of ammonia across the Sunshine Coast region, following its emission to the atmosphere from 41 poultry farms in the district. Both the dry and w et deposition of ammonia, directly into the Pumicestone Passage water body and also onto the surrounding catchment, were simulated for each hour over the entirety of 2005. The simulations indicate that most of the ammonia deposition occurs within a relatively short distance from the farms, although the annual loading into the w ater body is not insignificant and may contribute to the formation of algal blooms
