In this study, a novel characterization of heavy metal contamination in road dust collected from urban area with heavy traffic in Brno, Czech Republic is presented. The DGT probes were exposed in aqueous suspensions of particulate matter for different time periods to monitor for responses of the sample matter. The road dust and DGT sorption gels were decomposed by microwave assisted extraction and analyzed by inductively coupled plasma mass spectrometry for estimation of trace metals contents. The results revealed that the DGT technique is a useful tool for characterization of metals mobility, as a new alternative to conventional extraction procedures.
