“…Furthermore, our results indicate crude oil concentrations > 0.2% had a negative effect on plant growth by reducing RGR values. This is consistent with previous reports of the effect of diesel and crude oil on the RGRs of S. grossus (Al-Baldawi et al, 2015) and L. punctata (Ertekin et al, 2015) respectively. The hindering effect of oil on plant growth could be as a result of the phytotoxicity of the increased number of aromatic rings (Baek et al, 2004).…”

“…There is an increasing number of studies that evaluate the use of plants in the petroleum contaminated freshwater areas and in these researches different plant species such as Landoltia punctata (Ertekin et al, 2015), Vetiveria zizanioides (Effendi et al, 2017) and Lemna minor (Wang et al, 2017) have been used. Azolla has a special significance between the freshwater plants used in phytoremediation.…”

<p>In this study, the potential use of Azolla filiculoides Lam. for the bioremediative solution to polycyclic aromatic hydrocarbon (PAH) pollution due to crude oil spills in freshwater was investigated. The plants were grown in nitrogen-free Hoagland nutrient solution media containing 0.05%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% crude oil by volume for 15 days under greenhouse conditions. Relative growth rates of A. filiculoides decreased in the presence of crude oil in a concentration-dependent manner. The probable influence of A. filiculoides on the biodegradation of polycyclic aromatic hydrocarbons was measured by using synchronous UV fluorescence spectroscopy. GC-MS analysis were also carried out to elucidate the behavior of the oil in experimental and control samples. Although 1-2 rings PAHs have not been encountered in control or plant samples, the measured intensity for 3-4 ring PAHs in plant samples was remarkably lower in comparison to the control. Furthermore, these results demonstrated that the predominant efficacy of the A. filiculoides was for 3-4 ring PAHs at the range 0.05 to 0.2% crude oil concentrations. It could be concluded that the bioremediative potential of A. filiculoides for the removal of polycyclic aromatic hydrocarbons strongly depends on the amount of oil in the contaminated water resource. In other words, A. filiculoides could be used more effectively after the removal of excess crude oil in the spilled freshwater areas.</p>

“…Higher root metal concentrations and lower shoot metal concentrations at higher dose indicate restriction of Cd from the root to aerial parts via xylem sap flow. The present work, as well as Ertekin et al (2015) on Landoltia punctata and Torbati (2015) on Lemna minor, indicated the usefulness of aquatic plants for phytoremediation purposes for various pollutants.…”

Eichhornia crassipes is an abundant floating aquatic weed that has great potential for cadmium (Cd) remediation owing to its large biomass and relatively high tolerance and accumulation capabilities. This study was conducted with Eichhornia in 5, 10, 15, and 20 mg L -1 CdCl 2 in a hydroponic system for 21 days, and the Cd concentrations in the roots, shoots, and leaves were estimated. The plant showed tolerance, but at high Cd concentrations declines in biomass, root length, and leaf area were observed. Leaves showed a progressive decline in chlorophyll, carotenoid, and soluble protein and a significant elevation in lipid peroxidation. Cd uptake gradually increased in all the plant tissues up to 15 mg L -1 exposure, but at 20 mg L -1 the accumulation declined. Shoot tissues accumulated more Cd than root and leaf tissues. The highest accumulation by the plant was 1927.83 µg g -1 dry wt at 15 mg L -1 Cd. The maximum leaf, shoot, and root bioconcentration factors were 179.05, 187.59, and 169.3, respectively, and the maximum translocation factor of 1.003 was observed at 5 mg L -1 Cd. The root-to-leaf translocation of Cd was 100% efficient for all the doses of Cd exposure, except for 20 mg L -1 . The results of this study suggested that water hyacinth tolerated phytotoxic concentrations of up to 15 mg L -1 and efficiently hyperaccumulated Cd in its above-ground tissues.

“…Canatto et al (2021) considered L. punctata as a hyperaccumulating species of arsenate after observing the tolerance indices relative to different levels of this contaminant. Ertekin et al (2015) also indicated the species for phytoremediation of water contaminated with hydrocarbons from petroleum.…”

“…The species has a fast growth rate and the capacity to develop in wastewater, thus being a candidate for the phytoremediation processes (Stegemeier et al, 2017). The literature indicates that L. punctata is a species with a great capacity to bioaccumulate arsenic, nickel, zinc, and uranium (Nie et al, 2017) and petroleum hydrocarbons (Ertekin et al, 2015). In this context, this study aimed to assess fluoride mitigation by the species L. punctata when submitted to different values of phosphate, nitrate, and pH.…”
