“…Given this, this is often utilized to reduce the metal concentration of soils, sediments and waters (Bragato et al, 2006). P. australis has also been used to identify the presence of cd, cu, Pb and zn in estuaries, suggesting that it can be used as a bio-indicator (cicero-Fernandes et al, 2017). Agrostis stolonifera and Elytrigia repens are capable of forming tolerant ecotypes and are also characterized by a high ecological valence and resistance to heavy metals (Banásová, 2004;Boguská et al, 2013;Fazekašová et al, 2016).…”

This paper is focused on the impacts of alkaline and metal deposition on soil and vegetation in the immission field of magnesium factory Jelšava-Lubeník (Slovakia). Soil samples and the foliage of vegetation were obtained from the Jelšava-Lubeník area with specific alkaline pollutants. The examined area is one of the most devastated regions of Slovakia. From the point of view of environmental regionalization, it belongs to an environmentally damaged area of Category 3. The total content of heavy metals in the soil and vegetation (Pb, Zn, Cr, Mn, Mg) were determined by atomic absorption spectrometry and X-ray fluorescence spectrometry. Soil reaction was determined in a solution of 0.01 M CaCl2. Vegetation was assessed by the Braun-Blanquet scale. In conclusion, we can say that spray particles of free magnesium oxide (MgO) strongly influence soil reaction, diversity, and vegetation cover. The research showed that the investigated sites were mostly strongly alkaline; the contents of Cr, Mn and Mg were over the toxicity limit, while the measured values of Pb and Zn did not exceed the limits set by the law. The values that measured significantly above the set limit show contamination that can be considered harmful and toxic. In the monitored species, that is, Agrostis stolonifera, Elytrigia repens and Phragmites australis, an over-limit content of Pb and Zn and toxic contents of Mg and Mn were found.

“…ex Steudel (common reed) is one of the emergent plants used for the enhancement of water quality in water treatment systems (Ruiz and Velasco 2010;Eid et al 2020) due to its high growth rate and great ability for nutrient accumulation (Kiedrzy nska et al 2008). Utilization of the common reed as phytoremediators in eutrophic shallow lakes requires emphasis on the effect of nutrient loadings on reeds, but this effect has received little attention and is still not well understood (Zhao et al 2013;Cicero-Fern andez et al 2017). Therefore, the present study aims to investigate the potential of P. australis to remediate nutrients and restore a eutrophic wetland, Lake Burullus (a Ramsar site in Egypt).…”

The present study was conducted to investigate the potential of the emergent macrophytes Phragmites australis to remediate nutrients and restore an eutrophic wetland (Lake Burullus, Egypt). The plant was sampled monthly for one year from 6 sites distributed equally along the northern and southern parts of this lake. Monthly significant variation in all investigated sediment and water nutrients for the northern and southern sites was recorded. The biomass of P. australis in the southern sites was greater than that of the northern sites; in addition, the above-ground biomass was greater than the below-ground biomass. The above-ground biomass increased from February until it reached its maximum during August and then decreased again. Likewise, the highest nutrient concentrations in the different tissues were recorded at the beginning of the growing season during winter and early spring and then gradually decreased with increasing plant biomass. Moreover, the nutrient content (g/m 2 ) increased from the early growing season (February) and reached its peak during April-August and then decreased. Based on our results, P. australis could be used for the extraction of nutrients to reduce the eutrophication in Lake Burullus, if the above-ground biomass is harvested at its maximum value in August, as was the case regarding the maximum content of most nutrients.

“…Previous studies have indicated that phytoremediation process is expected to take many years to clean up a site (Rai 2008;Cicero-Fernández et al 2017). Both soils irrigated with high and low PTEs water showed a significant difference in the accumulation of Zn, Cu, Cd, Pb, and Ni in roots at the reproductive stage as well as the accumulation in rhizomes, stems, and leaves (Tables 3, 4, 5).…”

“…Comparison of total PTEs concentrations between aboveground (stem + leaf) and belowground (root + rhizome) tissues indicated that concentrations of the six metals were in all cases higher in belowground tissues than in aboveground tissues, since belowground are important parts for the takeup of HMs (Eid and Shaltout 2014), and subsequent translocation to aboveground parts could be limited (Mays and Edwards 2001;Stoltz and Greger 2002;Cicero-Fernández et al 2017).…”

This study investigates the impact of wastewater irrigation on soil-plant-water system at the vegetative, flowering, and reproductive stages of Phragmites australis for two and four days (in each stage) in the coastal saline area of Urmia Lake. The concentrations of potentially toxic elements were detected in irrigated water, soil, and plant (aboveground and belowground) tissues, and transfer factor and bioaccumulation factor were calculated. The shoot biomass was significantly increased with increasing wastewater exposure, up to four days after the flowering stage. All potentially toxic elements concentrations in belowground (roots and rhizomes) tissues were higher than aboveground (leaves and stems) tissues. Fe showed the maximum concentrations in all organs at different growth stages due to the higher level contents in soil and water. Fe was found to be the least mobile at the reproductive stage and presented in the following order: roots > rhizomes > leaves ≥ stems. By contrast, Zn and Cd metals which are quickly transported in plants exhibited the same trend. Pb was accumulated at the flowering stage as follows: rhizomes > roots > stems > leaves. The toxic threshold was exceeded by Zn, Fe, Cu, and Cd in roots; Fe in rhizomes, and leaves; Cd in rhizomes; and Ni in roots. There was more efficiency in the removal of chemical oxygen demand (61.09%), biochemical oxygen demand (73%), total suspended solids (50%), and ammoniacal nitrogen (59.5%) at the reproductive stage. Therefore, P. australis could be an efficient and valuable tool for the phytoextraction and phytostabilization of metals if harvested at the proper time of growth in high potentially toxic elements polluted coastal ecosystems.
