“…Littoral plants are commonly used in constructed wetlands to accumulate large amounts of heavy metals (Peverly et al, 1995;Southichak et al, 2006;Vymazal et al, 2009). There is still little data on the usefulness of these plants as bioaccumulators under natural conditions where relatively low concentrations of heavy metals occur (Southichak et al, 2006), and very little research on the use of littoral plants as heavy metal bioindicators and/or as buffers against the spread of heavy metals over large areas in a freshwater environment.…”

We measured cadmium and lead concentrations in two littoral plants (Phragmites australis Cav. Trin ex. Steudel and Typha angustifolia L.) collected in June and September 2007 from five selected lakes in the Poznan city area, and also in sediment and water samples from the same places. We determined the metal concentrations in rhizomes and leaves, and in sediment and water from the littoral and near the bank zone. Only low levels of the heavy metals were found. Pb and Cd concentrations were higher in water collected from the bank zone than from the littoral zone. Pb and Cd accumulation was noted in sediments. Heavy metal levels were higher in rhizomes than in stems and leaves. The studied aquatic macrophytes may be bioaccumulators and bioindicators of Pb and Cd in freshwater in natural conditions, even when concentrations are low.K Ke ey y w wo or rd ds s: : Cadmium, lead, accumulation, Phragmites australis, Typha angustifolia.ACTA BIOLOGICA CRACOVIENSIA Series Botanica 52

“…Transport of Pb to shoots was found in many other aquatic plant species, such as Eriophorum angustifolium (Stoltz and Greger 2002). However, Vymazal et al (2009) found very low translocation of this element to aboveground plant organs in constructed wetlands.…”

“…However, transport to aboveground organs is also observed. In the case of Cd, usually a higher amount was noted in belowground parts (Vymazal et al 2009), while in the case of Pb, mostly higher transport was recorded, hence a similar level as in belowground parts was observed (Peverly et al 1995). Nevertheless, there is still some concern about Cd transport to aboveground plant parts.…”

“…Also, some investigators found that Cd remains in roots, which act as good and effective fi lters (Peverly et al 1995). Vymazal et al (2009) found low Cd concentrations in shoots of P. australis growing in constructed wetland for treatment of municipal wastewater. On the other hand, some research revealed low transport of both heavy metals to leaves (Mazej and Germ 2009) or Pb as more portable element than Cd (Damodharan and Reddy 2015).…”

“…Most investigations have been carried out for the examination of aquatic plants in constructed wetlands for further use in municipal wastewater (Liu et al 2007, Vymazal et al 2009) and landfi ll leachate treatment (Peverly et al 1995). There are few investigations focused on possibilities of reduction of heavy metal concentrations by emergent plants in natural ecosystems, where usually lower levels occur.…”

Accumulation of Cd and Pb in water, sediment and two littoral plants (Phragmites australis, Typha angustifolia) of freshwater ecosystem

Cd and Pb concentrations were measured in water, sediment and plant organs collected from selective sites located along the Bogdanka river (Poznań, Poland) in the 2012 growing season. The aim of the investigations was to monitor changes in heavy metal (HM) concentrations in different media over the periods, as well as to evaluate potential of two littoral plants, Phragmites australis and Typha angustifolia, for phytoremediation under natural conditions. Investigations revealed differences in HM concentrations in water and sediments. Higher values were observed in sediments than in water. The decrease in concentrations of both HMs in sediments was noted in two of the three selected water reservoirs during growing seasons, which suggests the possibility of their adsorption and accumulation by aquatic plants. Both investigated plant species accumulated ample amount of Cd and Pb in underground and aboveground plant tissues, however T. angustifolia revealed higher Cd translocation potential than P. australis. The latter revealed higher Pb accumulation in two lakes. Moreover, the translocation ratio was usually higher in spring, especially for Pb, in both plant species. Increasing level of pollution load index in sediment along the Bogdanka watercourse indicates accumulation of measured HMs.

Bioremediation of Toxic Metals Using Aquatic Macrophytes: Challenges and Opportunities

Environmental pollution caused by urbanization, agricultural intensification, and industrialization has led to an increase in the disposal of toxic effluents in aquatic environments. Most ecosystems in the world receive a variety of toxic metals (TMs) that exceed the capacity of water bodies to absorb or recycle them, thereby threatening aquatic and human life. Physicochemical remediation methods encounter problems because of the high cost, labor input, and use of chemicals with long residence times that later add toxic by‐products. However, bioremediation techniques are a safe option for mitigating environmental pollution because of their high efficiency, cost‐effectiveness, non‐intrusiveness, eco‐friendliness, ease of application, and social acceptance. Submerged and free‐floating macrophytes were found to be more effective in the bioaccumulation of TMs than emergent macrophytes. Furthermore, most studies have suggested the use of macrophytes for the removal of TMs from water bodies; however, studies on the management of phytoremediated biomass are scarce. This review demonstrates the role of various macrophytes for the removal of TMs from water bodies and suggests techniques for the disposal and recycling of phytoremediated biomass with accumulated TMs. Further, the applications of genetically modified plants, nanotechnology, and native hyperaccumulators have been suggested as suitable candidates for greater efficiency of phytoremediation and appropriate management of TMs in the environment in the future.
