“…In the present study, it was found that Cd and Zn accumulated more in roots than in shoots. Similar results have been reported by several investigators in different species of plants 1,27,[31][32][33][34][35][36] . The differences in the ability of plants to accumulate heavy metals have been related to differences in their root morphology 37 .…”

ABSTRACT:The aquatic plant, Hydrocotyle umbellata, was tested for toxicity and accumulation of Cd and Zn under laboratory conditions. H. umbellata were cultured in modified 10% Hoagland solution supplemented with 0.2, 0.4, 0.6, 0.8 and 1 mg/L Cd and 2, 4, 6, 8, 10 and 50 mg/L Zn and were separately harvested after 3, 6, 9 and 12 days. The toxicity symptoms of H. umbellata exposed to Cd and Zn at different concentrations and exposure times were stunted growth and chlorosis in leaves. Finally, some plants died at higher concentrations of metals. The symptoms were more severe at higher metal concentrations. Cd and Zn caused significant decreases in biomass productivity and chlorophyll content when the exposure times and concentrations of both metals were increased. There were significant increases in metal levels in plant tissues when the exposure times and metal concentrations were increased. Both metals accumulated in roots more than in shoots. The high values of bioconcentration factor (BCF) of Cd (7173, at 0.2 mg/L) and Zn (1717, at 2 mg/L) on day 9 of exposure suggested that H. umbellata is a good candidate for removal of Cd and Zn from contaminated water.

“…Water pollution is clearly demonstrated by the high concentrations of heavy metals in the water, sediments and aquatic organisms 1 . Heavy metals are nowadays among the most important pollutants in source and treated water, and are becoming a severe public health problem.…”

“…The average concentration of Cd was lower in Skadar Lake than in other areas, but at location T8, which was contaminated with Cd ( Fig. 3), concentrations of Cd in all plant parts were similar to those in areas contaminated with metals (Sawidis et al 1995, Sweta et al 2015. In all plant species from Skadar Lake accumulation of metals decreased in the order Cr > Pb > Cd, following the levels of these metals in lake sediments.…”

-Skadar Lake is the largest shallow lake in southeastern Europe. It is located within a national park, and is included in the Ramsar List of international important wetlands, so its preservation and protection from pollution is very important. The aim of this study was to investigate bioaccumulation of the ecotoxic metals Cd, Pb and Cr from sediments of Skadar Lake in the aquatic macrophyte Trapa natans L. Samples of sediment and plants were collected at nine locations covering all major water inputs to the lake as well as locations where contamination could be expected. The obtained results indicate that sediments from the Skadar Lake are only locally contaminated with Cd (0.03-1.18 mg kg ). The highest bioaccumulation of all metals from sediment to Trapa natans L. was observed in the root, with accumulation effi ciency decreasing in the order Cd > Cr > Pb. Translocation from root to stem was also higher for Cd than for Cr and Pb, while the translocation from stem to leaf was comparable for all three metals. From the three investigated metals Cd showed the highest mobility. The results indicate that Trapa natans L. may be a very promising bioindicator of trace metal contamination in Skadar Lake.

Abstract:The publication is a synthetic review of many years of research on the possibility of using water plants (macrophytes) to assess pollution of surface waters and the possibility of using the biomass in phytoremediation processes. The results of the research of kinetics and equilibria of heavy metals sorption and desorption conditions were presented in order to repeatedly use the biomass, as well as the research on the influence of abiotic factors on sorption processes. Defence mechanisms of macrophytes, which enable them to vegetate in considerably polluted waters, have been discussed. The results presented herein and carried out in many countries demonstrate that macrophytes can be successfully used in the biomonitoring of water environments and phytoremediation of waters and sewage; however, validation of these procedures requires more detailed research of the mechanisms, which accompany them.
