Rural background studies serve mainly to assess the long-range transport influence and long-term trends. However, it is difficult to find a place with no influence of local sources. This is also the case of Košetice observatory having three small settlements within two km from the observatory. Therefore we attempted to analyze if the influence of these or other nearby sources can be seen in our data on PM2.5 chemical composition. Besides other possibilities like specific ratios of various gaseous compounds we concentrated on using size resolved number concentration data because of their dynamics that leads in general into particle growth until they reach accumulation mode. Several similar studies (e.g. Cusack et al. 2013) were performed during recent years.
