Phytoremediation of Zinc-Contaminated Industrial Effluents with Phragmites australis and Typha latifolia in Constructed Wetlands / I.Zinicovscaia, A.S.Krakovska, N.Yushin, A.Peshkova, D.Grozdov. – Text : electronic // Water. – 2025. – Vol. 17, No. 16. – P. 2358. – URL: https://doi.org/10.3390/w17162358. – Bibliogr.: 42.

This study evaluated the ability of two plants, Phragmites australis and Typha latifolia, to bioaccumulate zinc from industrial effluents in constructed wetlands using ceramsite as a support medium. Two types of experiments were conducted: one with real industrial effluent containing 9.4 mg/L of Zn and another with synthetic effluent containing Zn at concentrations ranging from 10 to 100 mg/L. Zinc uptake in plant segments, ceramsite, and its concentration in wastewater were determined using ICP-OES. Both plants removed 97–99% of zinc ions from the industrial effluent, with the highest metal uptake occurring in the roots. In the case of synthetic solutions, Typha latifolia demonstrated higher zinc removal efficiency (95–99% removal) compared to Phragmites australis (74–90%). Typha latifolia also accumulated significantly higher levels of Zn, primarily in the roots. Transfer factor values were calculated to assess zinc translocation within plant tissues. No visual signs of toxicity were observed during the experiment. This phytoremediation approach could represent a sustainable and environmentally friendly method for treating industrial effluents.
