Impact of Municipal, Road Traffic, and Natural Sources on PM10: The Hourly Variability at a Rural Site in Poland

The paper presents data from a monthly campaign studying the elemental composition of PM10, as measured by specific receptor in Kotórz Ma?y (Opole Voivodeship)—located vicinity moderately inhabited rural area—measured one-hour samples using Horiba PX-375 analyzer. hourly variability SO2, NO, NO2, CO, and O3 concentrations, well meteorological parameters, was also determined. On average, during entire measurement period, elements related to PM10 can be arranged following order: As < V Ni Pb Cr Mn Cu Ti Zn K Fe Ca Al Si S. Trace elements, including toxic elements—such As, V, Ni, Pb, Cr, Mn—were present low not exceeding 10 ng/m3 (average daily value). These had fairly even both hourly. concentrations main receptor, are subject strong changes only structures sources identified statistical analysis, but wind speed direction (soil sand particle pick-up inflow pollutants coal combustion). It has been shown that transport emissions have an intense effect on afternoon.
