“…However, numerous other studies emphasise the reverse effect [43]. Similar correlations are confirmed by other experiments [43][44][45][46]. It is supposed that better sorption characteristics of immersed plants are related to the specific structure of these macrophytes.…”

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.

“…It was reported that arsenic concentrations in the roots of Najas marina, Potamogeton lucens, Nuphar luteum (Linn.) and Potamogeton malaianus Mig were 15.9, 12.7, 8 and 7 g/g (dry weight), respectively, and the concentrations in the other parts were lower than 1 g/g (dry weight) [22], which were lower than those in the corresponding plants in Yangzonghai. The arsenic level in the root of Eichhornia crassipes (Mart.)…”

The arsenic contamination accident in Yangzonghai Lake, Yunnan has been of wide concern. In order to investigate the arsenic distribution and concentration trends after the accident, samples including lake water, sediments, soil, aquatic organisms and crops were collected in November 2008, as well as in February, May and September 2009. The average arsenic concentrations (arithmetic average) in lake water in the four sampling events were 176.9, 147.3, 159.3, and 161.1 g/L, while those in the sediments were 32.87, 62.41, 62.99, and 46.96 g/g, respectively. The highest content of total arsenic in soil in the vicinity of Yangzonghai was 23.33 µg/g, which was below the limits of the relevant national standard. The total arsenic levels in most aquatic plants were in the range of 100-200 g/g, with Vallisneria natans (Lour.) Hara having the highest concentration of ~300 g/g. The arsenic levels of fish and shrimps were in the range of 1.52-11.4 g/g (dry weight).

“…3), which could be a consequence of Pb absorption from the atmosphere through the leaf surface (Schreck et al 2012). Some other aquatic plants also demonstrated consistently higher metal concentrations in root than in stems or leaves (Cardwell et al 2002, Baldantoni et al 2004, Mazej and Germ 2009.…”

-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.
