Convective dust events are common in the greater Phoenix area over the summer. These short-duration dust events degrade the air quality and pose a potential health threat to millions. In this study, 85 convective dust events that occurred in July and August 2015 to 2021 were examined to determine their impact on air quality. Seven PM10 sensors were used to evaluate the changes in PM10 concentrations over different time intervals (10 minutes, hourly, and daily). Each dust event had to have at least one sensor with hourly PM10 concentrations >100 µg m-3. Out of these 85 dust events, only 16.5% had a daily average above the EPA PM10 daily threshold, however, daily concentrations were 11 and 14 times lower compared to hourly and 10-minute (respectively) concentrations at the peak of the dust. 10-minute PM10 concentrations were >2.3 times higher than the hourly concentrations. The findings of this study demonstrated that the traditional methods of daily or hourly average underestimate the atmospheric PM10 concentrations and therefore lower the estimated exposure. There is a need to consider shorter time intervals to capture the PM concentrations accurately and highlight the importance of real-time monitoring and accurate characterization of short-duration events to assess their impacts on air quality and human health.
