“…Metals investigated in this study show different chemical behavior in sediment and affi nity to the main sediment components, such as carbonates, Fe-Mn oxides, organic matter and aluminosilicates, and their mobility in sediment decrease in the order Cd > Pb > Cr (Filgueiras et al 2004), which explains the much higher BCF root/sed for Cd than for Pb and Cr. The same order of bioavailability of these three elements was found in other aquatic plants in Skadar Lake (Kastratović et al 2013(Kastratović et al , 2014 and also in the publications of other authors (Mazej and Germ 2009).…”

“…However, in India, in ponds highly contaminated with metals (including Cr and Pb), where this plant is cultivated as a source of food, high accumulation of Cr and Pb in Trapa natans fruit was found, indicating that, in polluted areas, accumulation of these metals may also take place (Rai and Sinha 2001). If we compare the metal bioaccumulation ability of Trapa natans with two other plants which were studied in Skadar Lake (Phragmites australis -Kastratović et al 2013 andCeratopgyllum demersum -Kastratović et al 2014) we can notice that the same order of metal bioaccumulation effi ciency (Cd > Pb > Cr) from sediment was found for all three macrophytes. However, Trapa natans showed the highest bioconcentration factors from sediment to root for Cd and Cr, thus further indicating that it may be a promising biondicator for metal contamination in the Skadar Lake.…”

“…Previous studies demonstrated that lake sediments are contaminated by metals, mostly Ni and Cr (Stešević et al 2007, Vemić et al 2014. Uptake of metals from water and sediment into two types of aquatic macrophytes from the Skadar Lake (Phragmites communis, Ceratophyllum demersum) was also studied (Kastratović et al 2013(Kastratović et al , 2014.…”

-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.

“…It is particularly present in aquatic environments in areas with heavy traffic and neighboring cities (Kastratović et al, 2013). In this present study, the mean concentrations of Pb in examinated tissues (12.34-14.48 μg/g) were below the phytotoxic range which is 30-300 μg/g (Roos., 1994).…”

“…Due to its ability to accumulate metals, availability throughout the year and large biomass, Phragmites australis (common reed) is suitable for biomonitoring studies for the evaluation of load levels of trace metals in aqueous ecosystems. The heavy metals concentration in P. australis tissues can be several ten to several thousand times higher than those in the surrounding water (Kastratović et al, 2013).…”

The content of heavy metals in sediment and the aquatic plant Phragmites australis (roots and leaves), collected from six different stations along the Nil river, were determined providing information about heavy metals pollution status of this aquatic ecosystem.The results showed that the abundance of heavy metals measured in the sediments decreased in the order: Fe>Zn>Pb>Cr>Cd. Apart from Cr and Fe, the concentration of heavy metals exceeded the background values. Metals concentrations were found decreasing with the increasing distance from the river mouth, suggesting that anthropogenic inputs, related to agricultural and domestic discharge into the river, are the major sources of heavy metals in the river sediments and aquatic plants.The assessment of heavy metals pollution was carried out using geoaccumulation index (Igeo) and enrichment factor (EF). According to the mean values of Igeo, the sediment of Nil river is considered as moderately polluted with Pb and Cd, unpolluted to moderately polluted with Zn and unpolluted with Cr and Fe. The mean values of enrichment factor indicate that all stations presented moderate enrichment with Zn, minor enrichment with Cr and moderately to severe enrichment with pb and Cd in three stations.Regarding the plant samples, the results showed that the concentration of the elements analyzed in Phragmites australis did not exceed the threshold of phytotoxicity.Mean concentrations of all elements were less in the plants organs compared to the concentrations of the same elements in the corresponding sediment sample. Metals accumulated by P. australis were mostly distributed in root tissues, as shown by the values of translocation factors (TF) which were <1. A positive association between the metal concentrations in P. australis organs and its environment was also found; this suggests that this plant can be used as biological indicator in biomonitoring studies.

The energy crop Miscanthus presents high potentials for phytomanagement. Its shoot yield and nutrient accumulation has been extensively characterized in uncontaminated agricultural soils, while very little is known for metal‐contaminated conditions. This study aimed at assessing potential differences in dry matter and metal and nutrient accumulation of the standing aerial biomass in Miscanthus (M. × giganteus) growing in situ on agricultural plots presenting different soil Cd, Pb, and Zn concentrations. Plant samplings were conducted monthly along the growing period from May to December. Cadmium, Pb, Zn, and the concentrations of the nutrients N, P, K, Ca, Mg, and Na were determined in leaves and stems separately. During the growing phase, the maximum dry matter was reached in early in autumn. Whatever the organ, Cd and Zn concentrations were higher on contaminated than on uncontaminated plots. During summer and autumn, Zn and Pb concentrations were higher in leaves than in stems whereas Cd concentrations did not significantly differ between the organs. Concentrations of N, P, K, and Mg decreased across the study period whereas those of Ca and Na increased. Overall, metal and nutrient concentrations depended on plant organ and its development stage. The dry matter and nutrient accumulation patterns were not different between contaminated and uncontaminated plots. The significance of these findings is discussed in light of best phytomanagement practices and potential uses of Miscanthus biomass.
