“…Biomass allocation, nutrient uptake and distribution, and fractionation of C isotopes were also altered by ZnO-ENMs ( Supplementary Tables 8-9). Similar effects have been previously described in aquatic macrophytes treated with toxic levels of ZnO-ENMs [4][5][6]8,10,51,52 , Zn 2+ (reviewed by 20 ), and other metals [53][54][55][56] . In our previous research on P. australis, exposure to 2 mM ZnCl 2 (131 mg l -1 Zn in solution) for 40 days caused a height reduction of 25% 44 .…”

“…As revealed by a combination of TEM and BET analyses, the as-synthesized porous adsorbents are most likely comparable in particle size and pore size distribution. Since the average particle size of MgFe 2 O 4 –OH NPs is only approximately 10 nm larger than that of MgFe 2 O 4 –NH 2 NPs, the particle size effect on adsorption capacity is then relatively negligible, according to the literature. , In addition, the pore size of the adsorbents plays an important role in adsorption kinetics when the pore size of the adsorbents is comparable with the size of the adsorbate molecules . However, if the pore size of adsorbents (particle size up to 0.1 mm) is much larger than the size of adsorbate molecules, the adsorption kinetics are independent of porous properties .…”

In this paper, the potential use of either amine-functionalized or hydroxyl-functionalized magnesium ferrite (MgFe2O4) nanoparticles (NPs) as Congo red nanoadsorbents is explored and compared. The amine-functionalized MgFe2O4 NPs (denoted as MgFe2O4–NH2 NPs) were synthesized by a one-pot coprecipitation method using ethanolamine as a surface modifier, while the hydroxyl-functionalized MgFe2O4 NPs (denoted as MgFe2O4–OH NPs) were prepared by a hydrothermal method. In general, both nanoadsorbents can be successfully produced without calcination and were found to possess superparamagnetic properties with high saturation magnetization (M s). In particular, MgFe2O4–OH NPs exhibit a higher M s value of ∼53 emu g–1, promoting the rapid separation ability of the NPs from the treated solution using an external permanent magnet. The Congo red removal performance of these nanoadsorbents was investigated as a function of the pH of the aqueous solution and contact time. The removal efficiency of Congo red by MgFe2O4–NH2 NPs was found to be ∼96% within 180 min at pH 6, while MgFe2O4–OH NPs provided a removal efficiency at ∼88% within 420 min at pH 8. In addition, the maximum adsorption capacities (q m) calculated using the Langmuir isotherm equation were found to be 71.4 and 67.6 mg g–1 for MgFe2O4–NH2 and MgFe2O4–OH NPs, respectively. The higher q m value of MgFe2O4–NH2 NPs could be attributed to stronger electrostatic interactions with the sulfonate groups of Congo red formed by larger numbers of protonated amine groups than protonated hydroxyl groups of the adsorbents under the performed conditions. Moreover, reusability experiments also revealed that MgFe2O4–NH2 NPs offered a higher removal efficiency than MgFe2O4–OH NPs for the same cycles tested. Therefore, this study demonstrates that MgFe2O4–NH2 NPs synthesized by a simple one-pot synthetic method are applicable as reusable magnetic nanoadsorbents for Congo red removal in current practice.

“…Studies have been conducted to investigate the flow of nanomaterials into aquatic and terrestrial environments. As regards plants, more aquatic [ 16 , 17 , 18 , 19 , 20 ] and wetland species [ 21 , 22 , 23 ] have been studied than terrestrial ones so far. To the best of our knowledge, Pinus sylvestris (L.) and Quercus robur (L.) are the only terrestrial wild plant species that have been investigated for exposure to silver nanoparticles ( n Ag) and cerium oxide nanoparticles ( n CeO 2 ) so far [ 24 ].…”

This study aimed to provide insight regarding the influence of Ce oxide nanoparticles (nCeO2) with different concentrations and two different particle sizes on the germination and root elongation in seedlings of spontaneous terrestrial species. In a bench-scale experiment, seeds of the monocot, Holcus lanatus and dicots Lychnis-flos-cuculi and Diplotaxis tenuifolia were treated with solutions containing nCeO2 25 nm and 50 nm in the range 0–2000 mg Ce L−1. The results show that nCeO2 enters within the plant tissues. Even at high concentration, nCeO2 have positive effects on seed germination and the development of the seedling roots. This study further demonstrated that the particle size had no influence on the germination of L. flos-cuculi, while in H. lanatus and D. tenuifolia, the germination percentage was slightly higher (+10%) for seeds treated with nCeO2 25 nm with respect to 50 nm. In summary, the results indicated that nCeO2 was taken up by germinating seeds, but even at the highest concentrations, they did not have negative effects on plant seedlings. The influence of the different sizes of nCeO2 on germination and root development was not very strong. It is likely that particle agglomeration and ion dissolution influenced the observed effects.
