“…E. hirsutum plants accumulated rather high concentrations of metals and As in biomass, whatever the condition (Table 3), in comparison with the commonly expected composition for control plants [53] and with the harmful concentrations for MPM and OMPM plants [54]. Overall, larger amounts of metals were retained in belowground (BG) parts than in aboveground (AG) parts of plants, as previously reported in other plant species exposed to metals [55][56][57].…”

For the treatment of wastewater containing organic pollutants and metals in constructed wetlands (CWs), phytoindicators may help in guiding management practices for plants and optimizing phytoremediation processes. Hairy willow-herb (Epilobium hirsutum L.) is a fast growing species commonly found in European CWs that could constitute a suitable phytoindicator of metal toxicity. E. hirsutum was exposed for 113 days in microcosm CWs, to a metal and metalloid mixture (MPM, containing Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Sn, Zn), an organic pollutant mixture (OPM, containing hydrocarbonsC10-C40, phenanthrene, pyrene, anionic detergent LAS) and an organic pollutant and metal and metalloid mixture (OMPM), separately and at concentration levels mimicking levels of industrial effluents. Analyses of metal and As concentrations in biomass, and different biometric and physiological measurements were performed. Results showed that metal uptake patterns were affected by the type of pollutant mixture, resulting in variation of toxicity symptoms in OPEN ACCESSWater 2015, 7 698 E. hirsutum plants. Some of them appeared to be similar under MPM and OMPM conditions (leaf chlorosis and tip-burning, decrease of green leaf proportion), while others were characteristic of each pollutant mixture (MPM: Decrease of water content, increase of phenol content; OMPM: reduction of limb length, inhibition of vegetative reproduction, increase of chlorophyll content and Nitrogen balance index). Results emphasize the potential of E. hirsutum as a bioindicator species to be used in European CWs treating water with metal, metalloid and organic pollutants.

“…Soil salinity values were heterogeneous, and interestingly, salinity is the critical factor controlling the distribution of plant communities within the study sites, corroborating those of several Algerian wetland studies (Aliat et al 2016, Chenchouni 2017). The current study shows that the levels of Pb (270-820 ppm) in DM and (101-278 ppm) in LT), Cd (1.84-8 ppm in DM and 1.79-3.17 in LT), Cu (118 ppm in DM) and Cr (97.14-508.87 ppm in DM) recorded exceeded AFNOR NFU 44-041 reference values (100, 2 and 150 ppm, respectively), and are higher than those reported by several authors of wetland soil studies (Teuchies et al 2013, Belabed et al 2017, Esmaeilzadeh et al 2017. In addition, nickel and zinc concentrations in DM and LT soils in the present study are homogeneous and vary only slightly.…”

Algerian natural wetlands suffer from anthropogenic disturbances due to industrial development and urbanization. This study was designed to draw attention to arbuscular mycorrhizal fungi (AMF) distribution and community assemblages following heavy metal and salinity concentrations in two wetlands subjected to domestic and industrial effluents. Rhizospheric soil and roots of 18 plant species were collected in two wetlands along a decreasing salinity gradient. The results showed that 72.72% of plant species exhibit an association within arbuscular mycorrhizas (AM), and 36.36% a dual association between AM and dark septate endophytes (DSE). A total of 33 AMF morphospecies were distinguished on the basis of morphological criteria dominated by taxa belonging to Glomeraceae and Acaulosporaceae. Soil contamination was investigated by determining metallic trace elements (MTE) (Cd, Cu, Ni, Pb, Cr and Zn) using an atomic absorption spectrophotometer. Values of the pollution index revealed wetlands that were particularly polluted by lead. Two˗way ANOVA showed significant variations in metal content among sampling locations and transects. Principal component analysis showed that species richness, and mycorrhizal frequency were slightly affected by MTE. This opens possibilities for their utilization in polluted soil remediation.

“…High enrichment factors (higher than unity) of Mn and Cr for S. erectum; Zn, Co, and Cr for Phalaris arundinacea; Mn and Cu for Phragmites australis; and Cr for G. maxima indicate that these plants absorb and transport metals from sediment and store them in their leaves (Branković et al 2011). High enrichment factors (Teuchies et al 2013) and high metal accumulation by the species studied make them an interesting tool for phytoremediation of aquatic ecosystems contaminated with these metals. All species studied except of G. maxima were found to be accumulators of several metals.…”

In the present study, the concentrations of trace and alkali metals in leaves of four common helophytes, Sparganium erectum, Glyceria maxima, Phalaris arundinacea, and Phragmites australis, as well as in corresponding water and bottom sediments were investigated to ascertain plant bioaccumulation ability. Results showed that Mn and Fe were the most abundant trace metals in all plant species, while Co and Pb contents were the lowest. Leaves of species studied differed significantly in respect of element concentrations. The highest concentrations of Mg, Na, Fe, Mn, Cu, Pb, and Ni were noted in S. erectum while the highest contents of Co, Ca, Zn, and Cr in Phalaris arundinacea. Phragmites australis contained the lowest amounts of most elements. Concentrations of Co, Cr, Fe, and Mn in all species studied and Ni in all except for Phragmites australis were higher than natural for hydrophytes. The leaves/sediment ratio was more than unity for all alkali metals as well as for Cu and Mn in Phragmites australis; Cr, Co, and Zn in Phalaris arundinacea; Cr and Mn in S. erectum; and Cr in G. maxima. High enrichment factors and high levels of toxic metals in the species studied indicated a special ability of these plants to absorb and store certain non-essential metals and, consequently, their potential for phytoremediation of contaminated aquatic ecosystems.
