Abstract
Air pollution caused by particulate matter (PM) remains one of the major urban environmental and health concerns. The differences between the size fractions of particulate matter (PM₁, PM₂.₅, PM₄, PM₁₀) reflect the differences in sources and atmospheric processes. Hence, it becomes necessary to apply size-resolved and number-based analysis for the interpretation of aerosol behavior. The present study aims at examining the characteristics of particulate matter mass concentrations and particle number concentrations (CN) in the urban environment, focusing on pollution episodes, the impact of traffic, and the control of meteorological conditions. Hourly concentrations of particulate matter (PM₁, PM₂.₅, PM₄, PM₁₀) and particle number concentrations (CN) were measured at Turin, Italy, using a Palas Fidas 200S aerosol spectrometer.
The instrument was deployed at an outdoor monitoring station
