Air and Waste Management Annual Conference Proceedings. (ACE 2014) Held 24-27 June 2014, Long Beach, California, USA. Manuscript #33537, 7 pages.. Interpretive Summary: Technical Abstract: Studies of air quality indicate that agricultural emissions may impact particulate mass concentrations through both primary and secondary processes. Agriculture impacts can include primary dust emission, on-facility combustion from vehicles or seasonal field burning, and gaseous emissions from waste holding areas such as ammonia that can produce secondary aerosol. During this study we field tested an ambient ion monitor (AIM) adapted for detection and quantification of agricultural emission components. Sampling took place at Mammoth Cave National Park during two time periods. The AIM instrument was co-located with measurements by other agencies at the park.. Results from AIM sampling in both cases show that ammonia was present as a major cation component of the particles. Other secondary aerosol components potentially representing agricultural emissions such as the amines and carboxylic acids were not detected during either sampling period. One controlled burn plume appeared to be detected during the sampling period. |
