“…Root vitality under high NaCl conditions were the worst, which became fragile and thinner and also showed strong inhibition of branching and growth. The change in physiological indicators of plant may be influenced by soil environment conditions (Li et al, 2008;Gao et al, 2015). 100mM NaCl treatment caused reduction of root vitality.…”

“…It coheres with results reported by Gao et al . () who observed the Cd removal efficiency of 91.8% in the case of a subsurface vertical flow constructed wetland planted with I. sibirica . Cd can be removed by particulate settling and trapping, chemical precipitation, partitioning to sediments and by plant uptake (Kadlec & Wallace ).…”

Removal of Pb, Cd, Cr, Mo, V, Be and Ba from municipal wastewater using a horizontal subsurface flow constructed wetland was studied. The removal efficiencies attained for these elements were 50, 86, 71, 59, −53, 37 and 40%, respectively. The average inflow and outflow Pb concentrations were 1.5 and 0.7 µg/L. Similarly, the inflow and outflow concentrations of 0.14 and 0.02 µg/L were obtained for Cd. Cr inflow and outflow concentrations were 3.7 and 1.1 µg/L, respectively. Concentrations of 0.78 and 0.32 µg/L were measured for Mo. V was washed out from the system. Its average inflow and outflow concentrations were 4.8 and 7.4 µg/L, respectively. Be inflow and outflow concentrations were rather low (1.03 and 0.65 µg/L), however, the concentrations of Ba were significantly higher (189 and 113 µg/L). The main perspective of the constructed wetland is the removal of toxic elements forming insoluble compounds (e.g. CdS) depositing in the wetland bed.

In the present experiment, a horizontal flow constructed wetland (HFCW) planted with Typha angustifolia, was tested to bioremediation potential for arsenic from mine effluent at the field in largest borax reserve area over the world, Kırka (Eskişehir). Briefly, the objective of the present experiment was to investigate arsenic bioremediation capability of wetland system and asses the phytoremediation efficiency of T. angustifolia, selected as a donor plant in this study, with different initial arsenic concentrations. The results indicated that HFCW has capability to decreased arsenic in mine effluent from 49 µg L -1 to 21.8 µg L -1 in a period of 84 days, suggesting that HFCW can defined as a reasonable low-cost treatment tool to prevent arsenic pollution. Furthermore, arsenic level in outflow samples of HFCW was stably below 10 µg L -1 (drinking water safety limit) with an inflow range from 42.3 to 42.1 arsenic µg L -1 during the first 28 days. The results also indicated that belowground parts of T.angustifolia accumulate more arsenic from mine effluent compared to aboveground parts during experiment period. Therefore, the results suggested that belowground parts of the plant in HFCW play an important role for arsenic bioremediation from mine effluent which origin of Kırka Borax reserve area. In this respect, bioconcentration factor (BCF) for the plant which grown in HFCW was found higher than those of control group. Moreover, results of the present experiment also concluded that relatively high level of arsenic retained in the filtration media of HFCW during experiment period, indicating that filtration media which was used in HFCW can remediate arsenic from mine effluent. Consequently, the scientific insight of the present experiment can defined as present an innovative, cost effective, and easy operating method for arsenic remediation from mine effluent.
