This paper describes the relationships between concentrations of selected  trace elements in soil and their bioaccumulation in aerial parts of three  Veronica species (Plantaginaceae). Plant and soil samples were collected from  three mountainous areas in Serbia, prepared by microwave acid-assisted  digestion and analyzed by flame and flameless atomic absorption spectrometry.  Total concentrations of Cu, Zn, Mn, Fe and Cr in the soil varied from 12.38  to 47.77, 62.78 to 138.00, 517.58 to 1675.78, 13574.22 to 35920.00 and 36.18  to 115.15 mg/kg, while those in the plants ranged from 6.04 to 12.8, 27.66 to  58.01, 25.38 to 89.25, 35.53 to 563.26 and 0.44 to 18.96 mg/kg, respectively.  There were no significant differences in heavy metal concentrations between  tested Veronica species from the same location, indicating that their heavy  metal uptake pattern was not species specific. In the case of Mn, despite its  wide variation in soil, concentrations in plant samples were uniform, which  suggests potential ability of tested species to control Mn uptake or  translocation to upper plant parts. Additionally, the lowest concentrations  of Cu were obtained in plant samples collected from soil with the highest Fe  concentrations, pointing out that Cu availability to plants might be reduced  due to high Fe content in soil solution
