This document provides an overview of non-point source (NPS) air pollution emissions in Alberta, Canada. It shows that in 2011, 64% of particulate matter emissions in Alberta came from road dust, while agriculture accounted for 90% of ammonia emissions. The document also notes that stationary air quality monitoring shows improvements from 2005-2010, but mobile monitoring identified some areas with increased air pollution. Finally, it defines NPS as aggregated small sources of emissions that are too numerous or widespread to measure individually, such as vehicle exhaust, farming activities, and residential fuel combustion.
