Characteristics of heavy metal contamination in road dust collected from urban area with heavy traffic in Brno (Czech Republic) was investigated. The DGT probes were exposed in aqueous suspensions of particulate matter for different time periods to monitor responses of the sample matter. The results revealed that the traffic appears to be responsible for the high levels of Cu, Pb, Ni and Sb and also that DGT technique, as alternative to conventional extraction procedures is a useful tool for characterization of metals mobility.
