This study aimed to reveal the dependence of the spatial distribution of heavy metals in soil on the morphography of the Lower Danube floodplain in the Ostrovska Lowland in Bulgaria. The field campaign was conducted in 2017, and the concentration of Zn, Ni, Pb and Cr were measured in the fine fraction (<0.063 mm) of 10 soil samples using X-ray fluorescence analysis. The average content of Cr in the topsoil (0-20 cm) was 127 mg/kg ranging between 98 – 171 mg/kg. It was followed by Zn – 81 mg/kg (60 – 128 mg/kg), Ni...
