Analysis of Elemental and Organic Carbon Eerosols: Crossroad vs. Suburban Area
Vodička, Petr ; Schwarz, Jaroslav ; Smolík, Jiří
Contribution present measurements of elemental and organic carbon aerosols during three measuring campaigns in periods 12.-15.5.09, 24.-27.8.09 and 6.-9.10.09. Measurements were performed in parallel at the crossroad Kamýcká-Suchdolská (outskirt part of Prague) and the Institute ICPF areal (urban background station). Measurements were carried out on on-line devices, in the two-hour intervals, with temperature program Eusaar2 on PM2.5 size fractions. The measurement results show that the field on-line device for measuring ECOC are suitable for monitoring of emissions from transport. Two-hour time resolution it allows to monitor the traffic intensity fluctuations caused by air pollution.

Dynamika velikostního rozdělení částic atmosférických aerosolů v Praze - Suchdole
Matějková, Daniela ; Ždímal, Vladimír ; Schwarz, Jaroslav ; Smolík, Jiří
This work summarizes first results of a one-year-long continuous sampling by SMPS and APS spectrometers at the suburban backgrounds site in Prague-Suchdol. The average particle number concentration was found to be 6500 particles/cm3. The size distributions were mostly monomodal with the mode located either in the Aitken (21-100 nm) ot the accumulation range. The dynamic of particle size distributions and especially situations when we found elevated concentrations of particles smaller than 25 nm were studied. New particle formation belonging to the category Banana event was identified most frequently. The average values of J3, were estimated to be 1.8 cm3s-1 and GR 6.6 nm h-1.
