“…The ability of A. filiculoides to accumulate heavy metals from treating solutions has been highlighted in several studies. For example, treatments of A. filiculoides with solutions containing Ni, Cd and Pb- cations (5, 10 and 25 mg/L) showed an increased removal efficiency (from 40 up to 70%) by increasing the contact time up to 10 days [ 40 ]. Khosravi et al [ 49 ] revealed that living samples of A. filiculoides were able to remove Pb 2+ , Cd 2+ , Ni 2+ and Zn 2+ from aqueous solutions enriched by 4 mg/L of metal ions and their presence caused up to 42% inhibition of biomass growth.…”

“…Thanks to this nitrogen-fixing ability, it can be used also to stimulate the growth of crops in water (e.g., rice) [ 38 ]. Furthermore, thanks to its ability in removing heavy metals and other contaminants (e.g., azo dyes, hydrazine) from the aquatic environment, this species has been studied for potential applications in phytoremediation processes [ 39 , 40 , 41 , 42 , 43 ]. In addition, it has been employed as a non-target organism to detect the potential effects of pharmaceuticals released in the aquatic environment [ 44 , 45 ].…”

Treatments of crops with additives to increase their productivity may pose environmental risks and induce negative effects also on non-target organisms. In this study, we investigated the potential effect of chestnut wood distillate (pyroligneous acid) used in agriculture, on the accumulation of trace elements in aquatic plants. As a model species, the common water fern Azolla filiculoides Lam. was selected, being often used also in phytoremediation processes. The content of selected elements of toxicological concern (As, Ba, Cd, Cu, Fe, Mn, Ni, Pb, Zn) was assessed in the fern after short-term treatments (1–3 days) over a range of wood distillate concentrations 1:300 (3.33 mL/L), 1:500 (2.00 mL/L), 1:700 (1.43 mL/L). A statistically significant accumulation of Cd, Cu, Mn, Pb, Zn (1:700) and Pb (1:300) was recorded after three days of incubation, despite the concentrations remained overall low. Using treatment vs. control ratios, a trend of increasing temporal uptake was detected for As, Ba, Fe, Mn, Pb (1:700); Mn, Pb (1:500), and only Pb at 1:300. The results suggested that, under the experimental conditions, element uptake is positively influenced by time and negatively by increasing concentrations of wood distillate, likely due to the acidification of the medium. On the whole, the element concentrations measured in A. filiculoides were low and did not pose any toxicological concern.

“…The authors have used both whole plants (e.g. Lemna gibba (Morales-Barrera et al 2020), Azolla filiculoides (Naghipour et al 2018), Pistia stratiotes or Nymphaea lotus (Ugya et al 2019)) and various plant fragments in their studies. For nickel sorption, both plant parts such as bark (Cancelo-Gonza ´lez et al 2017;Akar et al 2019) or cones (Oguz 2020), and more fragmented parts such as fibers (Boudaoud et al 2017), bagasse (Rico et al 2018;Candelaria et al 2019) and sawdust (Richard et al 2020) were used.…”

The use of materials of natural origin for the adsorption of heavy metal ions from aqueous solutions has gained attention in recent years among the scientific community. This is explained by the fact that nickel compounds, due to severe health consequences, are considered to be among the most dangerous to the environment. This article reviews the results of studies on the use of biosorbents for purification of aqueous solutions from nickel ions, and then attempts to classify them according to their origin. The characteristics of materials and their sorption capacity have been compared, and the removal mechanisms identified of which chemisorption and ion exchange are considered to be the most common. From the analyses, a major trend is the use of biomass; however, biosorbents from other groups also continue to attract the interest of researchers. Conducting laboratory studies can help select materials with high efficiency. The highest sorption capacity values for the materials in each group were: for waste products 56 mg Ni·g−1 (olive stone), for peat 61 mg Ni·g−1, for miscellaneous 225 mg Ni·g−1 (microbial flocculant GA1), for biomass 286 mg Ni·g−1 (Plantanus orientalis bark) and for composites/modified materials calcinated eggshells 769 mg Ni·g−1 (calcinated eggshells). However, for some materials the sorption phenomenon may be accompanied by precipitation in the presence of hydroxides, which significantly affects the sorption capacity achieved. There is a need to transfer these experiments to an industrial scale so as to verify their applicability. In such industrial scale applications, attention should be paid not only to the effectiveness of the material, but also to its availability, price, and ease of use, as well as the effect of the biosorbent in terms of changing the quality parameters of the aquatic environment.

“…In particular, Azolla filiculoides has been chosen due to its high biomass production, metal accumulation ability (Valderrama et al 2013;Naghipour et al 2018) and free floating nature, all positive characteristics for phytoremediation purposes. In addition, the high water content typical of A. filiculoides fronds (Serag et al 2000) drastically reduces the problems of disposal (Sood et al 2012) and its ability to make symbiotic relationship with the heterocystous blue-green alga, Anabaena azollae, allows its growth also in contaminated low nitrogen environment.…”

Water ecosystems polluted by heavy metals, such as cadmium, may also be affected by the increasing presence of TiO2 NPs. Several researchers have studied the effects of the two contaminants individually, however only a few studies on their joint action have been published for plants. Focusing on the aquatic environment, the hydrophyte Azolla filiculoides can be a useful model to assess if TiO2 NPs may in some way alleviate the Cd injuries and improve the ability of the plant to cope with this metal. With this mechanistic hypothesis, after a pre-treatment with TiO2 NPs, A. filiculoides plants were transferred to cadmium contaminated water with or without TiO2 nanoparticles. After five days of treatment, cadmium uptake, morpho-anatomical and physiological aspects were studied in plants. The continuous presence of TiO2 nanoparticles, though not increasing the uptake of cadmium in comparison with a priming treatment, induced a higher translocation of this heavy metal to the aerial portion. Despite the translocation factor was always well below 1, cadmium contents in the fronds, generally greater than 100 ppm, ranked A. filiculoides as a good cadmium accumulator.Higher cadmium contents in leaves did not induce damages to the photosynthetic machinery probably thanks to a compartmentalization strategy aimed at confining most of this pollutant to less metabolically active peripheral cells. The permanence of NPs in growth medium ensured a better efficiency of the antioxidant apparatus (proline and glutathione peroxidase and catalase activities), induced a decrease in H2O2 content, however was not able to lower the oxidative damage (in terms of TBARS).
