Maksimović T., Rončević S., Kukavica B.: Utricularia vulgaris L. and Salvinia natans (L.) All. heavy
metal (Fe, Mn, Cu, Zn and Pb) bioaccumulation specificity in the area of Bardača fishpond. Ekoló-
gia (Bratislava), Vol. 38, No. 3, p. 201–213, 2019.
Paper deals with seasonal changes in heavy metal bioaccumulation (Fe, Mn, Cu, Zn and Pb) in
Utricularia vulgaris L. and Salvinia natans (L.) All. of two localities (Necik and Sinjak – active
fishpond basins) in the area of Bardača fishpond. According to our results, the better accumulator
of Fe (3035 mg/kg) and Zn was S. natans (163.55 mg/kg), whereas Utricularia vulgaris better accu-
mulates Mn (620 mg/kg) and Cu (10.18 mg/kg). Amounts of Pb in both investigated macrophyte
were below the detection level (1 or ~1 for both species, and the BAC values decreased in the following
order in both investigated species: Fe > Mn > Cu > Zn. The results obtained indicated that tested
macrophyte show very good characteristics as bioaccumulators and, thanks to this fact, they could
be used in phytoremediation technique successfully in water-polluted ecosystem.
