Due to diverse natural characteristics and miscellaneous anthropogenic pressures, the Sava River is a suitable model system for investigation both natural and anthropogenic inputs influencing the chemical dynamics of a riverine ecosystem including riparian zone. The aim of this screening was to assess the spatial distribution of arsenic and heavy met
als (Cd, Cr, Cu, Hg, Ni, Pb and Zn) in a riparian soil influenced by periodical flooding
along a considerable stretch of the Sava River. Soil samples ( depth of 0-10, 10-20 and 20-30cm) were collected during the GLOBAQUA expedition in September 2014 at 10 sites, extending over 945 km of the upper, middle and lower stretch of this mighty river. Our preliminary results revealed significant differences (Man-Whitney-U test, for p<0.05)
between the examined sites for all the trace elements except for Cu and Zn. Distribution
of trace elements in relation to the different soil depths showed no significant differences.
The concentration of As, Cd, Cr and Ni exceeds both background concentrations of trace metals in common soil types worldwide [l], and background values for European soils[2] in the lower stretch of the river (.Zupanja in Croatia, and Sremska Mitrovica and Belgrade
in Serbia). The concentarion of Pb was found to be higher at two sites in the upper stretch
(Radovljica and Litija, Slovenia), Fig. I, in compare to all other sites.
Our results indicated higher anthropogenic pressure in the lower stretch of the Sava River, which is in accordance with the previous studies [3]. More efforts should be focused on the study of riparian area of large rivers in order to better understand transport of pollut
ants and influence of the rivers to surrounding area, and vice versa. It is particularly im
portant since extreme hydrological events (flooding and very low water levels) frequently occur within the study area that may considerably influence pollutants transport and their
remobilization.
