Abstract: Ammonia is a significant gaseous pollutant present in the atmosphere. As a neutralizing agent of acidic species ammonia forms particle-phase ammonium (NH4+) salts and contributes thus to formation of secondary atmospheric aerosols (Harrison and Jones, 1995). Aerosols (particulate matter, PM) are responsible for many negative effects on environments and health risks to human. The diameter of PM has significant impact on their environmental exposure, where the decreasing particle size increases the adverse health effects. The ultrafine particles hence play a major role in adverse impact on human health (Ryer-Powder, 1991). Presented paper describes the use of the novel continuous aerosol sampler for online, and a commercial cascade impactor for offline, determination of NH4+ in ambient air.
