“…The direct dependence of the change of phytotoxic indicators on the concentration of contaminants was observed: the higher the dose, the lower the germination rate as well as radish root length. Researchers also noted the negative impact of metal-based NPs on the state of plants [ 12 , 13 , 14 , 41 ].…”

“…The analysis of the studies already carried out demonstrated the ambiguity of the results obtained: some authors indicate the absence of a negative impact of NPs entering the environment, while others note a considerable negative impact of the interaction of NPs with environmental components [ 12 , 13 , 14 ]. A negative impact on the number and activity of bacteria in the soil was recorded under contamination with CuNPs [ 15 , 16 ], ZnNPs [ 13 , 17 , 18 ], and NiNPs [ 15 ]; on the state of plants when contaminated with CuNPs [ 19 , 20 , 21 , 22 ], NiNPs [ 15 , 23 , 24 ], and ZnNPs [ 25 , 26 , 27 ] and on enzyme activity in soil upon contamination with CuNPs [ 28 , 29 , 30 ], ZnNPs [ 29 ], and NiNPs [ 15 , 31 ]. However, a number of studies have noted the stimulating effect of ZnNPs and CuNPs on the enzymatic activity of soils [ 32 , 33 , 34 ] and the state of plants [ 35 , 36 , 37 , 38 , 39 , 40 ].…”

“…To assess the state of soil after pollution, it is advisable to use indicators of the biological state of soils, such as the activity of soil enzymes, changes in phytotoxic indicators, and the number of soil bacteria [ 9 , 13 , 15 , 30 , 31 ]. Thanks to these biological indicators, it is possible to assess the state of the soil after and during pollution, as well as to assess the rate of restoration of soil health.…”

An increase in the penetration of metal-based nanoparticles (NPs) into the environment requires an assessment of their ecotoxicity as they impair the critical activity of plants, animals, bacteria, and enzymes. Therefore, the study aimed to observe the effects of metal-based NPs, including copper (Cu), nickel (Ni), and zinc (Zn), on the Cambisols, which cover a significant part of the earth's soil and play an important role in the biosphere. Metal-based NPs were introduced into the soil at concentrations of 100, 1,000, and 10,000 mg/kg. The biological properties of the soil are being investigated as the most sensitive to external contamination. The highest ecotoxicity of the studied pollutants introduced into the soil at the same concentrations was shown by Cu (up to 34%) and Zn (up to 30%) NPs, while Ni NPs showed less (up to 22%). Microbiological (total number of bacteria, Azotobacter sp. abundance) and phytotoxic properties (radish seed germination and length of roots) of Cambisols were more sensitive (22–53%) to pollution by NPs of Cu, Zn, and Ni, while enzymatic activity (catalase and dehydrogenases) showed less sensitivity (14–32%). The present results could be useful for biomonitoring the state of contaminated soils, especially by NPs.

In this research article, we have fabricated the zinc oxide (ZnO) nanoparticles (NPs) with help of aqueous extract of leaf of Origanum majorana and studied their antimicrobial activity. Origanum majorana is one of medicinally important plant of Lamiaceae/Labiatae family. Green-approach of NPs has been favoured over traditional synthesis methods, as plant-based extracts have phytochemicals, which are non-toxic and biologically safe. The phytochemicals such as flavonoids, derivatives of phenol and polyphenolic biomolecules are found to be in aqueous leaf extract of Origanum majorana which used as capping and reducing agents. They include many functional groups such as-OH, -C=O and more which improve the physicochemical properties of NPs and consequently affect their targeting towards specific molecules. Plant mediated synthesis of ZnO NPs with fresh leave extract of Origanun majorana is also simple, quick and provides a vast array of functionalised NPs of particular size and morphology. Herein, ZnO NPs have been prepared with 3 mL of 25% (w/v) of leaf extract of Origanum majorana (Maruva). These synthesized NPs have been characterized using PXRD (Powder X-ray diffraction), FT-IR (Fourier transform-infra-red spectroscopy), UV-Visible spectroscopy, SEM (Scanning electron microscopy) with EDS (Energy dispersive spectroscopy). UV-Visible spectrum shows maximum absorbance at 379.75 nm and energy band gap have been evaluated 2.84 eV using tauc plot. Obtained PXRD pattern shows hexagonal wurtzite crystalline structure which is similar as reported in the literature (JCPDS No-36-1451). The morphology of synthesized NPs has been obtained with SEM images. These NPs are rod shaped with width calculated approximately 90 nm-125 nm and length 0.5μm-1.2μm respectively. The EDS analysis shows the 51.41% of zinc (Zn) and 48.49% of oxygen (O)elemental composition of fabricated nanoparticles. Antimicrobial activity has been performed on gram negative and gram positive microbes with the help of broth dilution method. These synthesized NPs shows very great bactericidal activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Streptococcus pneumoniae respectively. Minimum inhibitory concentrations (MIC) have been investigated 175μg/mL for Pseudomonas aeruginosa, 125 μg/mL for Escherichia coli and 100 μg/mL for both the Staphylococcus aureus and Streptococcus pneumoniae respectively.

“…Physico-chemical synthesis routes have many drawbacks, such as high energy consumption, high cost, laboriousness, and the generation of hazardous waste. Nowadays, biosynthesis is the method of choice due to cost-effectiveness, simplicity, and eco-friendliness (El-Belely et al 2021;Fagier 2021;Gangwar & Sebastian 2021;Huang et al 2021;Murali et al 2021;Nityasree et al 2021;Ramesh et al 2021;Soltanian et al 2021;Thi et al 2021;Thirumoorthy et al 2021). In addition, the synthesis of ZnO using agricultural waste adds economic and environmental value to the waste.…”

Zinc oxide nanoparticles (ZnO NPs) were biosynthesized. According to GC/MS analysis, chalcone; the main phytochemical; is probably complexed with Zn ions that are then oxidized to ZnO NPs by atmospheric O2 during heating. The ZnO NPs were characterized by TG, FTIR, XRD, FESEM, TEM, eEDAX, and BET surface area analysis. Sphere-like ZnO NPs were formed with 11 nm mean crystallite size, 5.2 m2 g−1 surface area, and 0.02 cm3 g−1 total pore volume. The synthesized ZnO showed excellent photocatalytic degradation (96.5±0.24% in 1 hour at 25 °C) of malachite green (MG) in aqueous solutions under UV light at optimum conditions; pH 10, MG initial concentration of 20 mg L−1, and ZnO dose of 1.5 g L−1. Also, ZnO showed very good reusability (92.9± 0.2% after 5 runs). The experimental data obeyed pseudo-first-order kinetics (R2=0.92). The photocatalysis process is dependent on the following species in the order: OH. > electron/positive hole pairs > O2.−. Moreover, photodegradation efficiency decreased in the presence of CO32−, HCO3−, and Cl−, but increased in the presence of NO3−, and SO42− ions. Thus, the green synthesized ZnO NPs can be applied as an efficient photocatalyst for the removal of MG from aqueous media.
