Laboratory experiments suggest that strong acids promote formation of enhanced levels of secondary organic aerosol (SOA), and organic aerosols may contribute to the health impacts of fine PM. We report results from examining hourly speciated fine par

Continuous measurements were made of gaseous NH 3 , gaseous HNO 3 , PM 2.5 sulfate, aerosol mass, air temperature, and relative humidity (RH), and 24-h filter samples of PM 2.5 aerosols were analyzed to determine the effects of ambient NH 3 levels on

Current fine particle NAAQS specify 24 h integrated mass measurements as the compliance metric. However, the value of continuous short-time resolution sampling (1 h or less) is recognized and being included in US EPA-monitoring strategies. An extensi
