In this work, we developed and used research methods that will make it possible to quickly assess the toxic activity of, among others, metal nanoparticles. In this work, we assessed the toxicity of PbO nanoparticles obtained from biological synthesis using Farfarae folium. The obtained PbO nanoparticles were characterized with the use of such methods as UV-VIS, XRD, SEM with EDS, AFM and FTIR. The techniques applied in the work confirmed the presence of 30-40 nm PbO nanoparticles.The toxic properties of biologically synthesized nanoparticles were assessed with the use of plants and invertebrates. The phytotoxicity studies were conducted on the following plant seeds: radish, garden cress, bean, rape, chia, lupine, corn, and beetroot. The IC50 coefficient was calculated on the basis of the logarithmic relationship A w = a*ln(C) + b. The studies also used the following invertebrates: Daphnia pulex, Tubifex tubifex, Chaoborus sp. (larva), Chironomus aprilinus, Artemia sp. The EC50 coefficient was calculated after the incubation period. For PbO nanoparticles, we managed to identify the IC50 coefficient for selected plants. It was, respectively, 0.150 mg/ml for lupine; 0.274 mg/ml for bean; and 0.655 mg/ml for radish.As regards the studies on invertebrates, it was observed that the most sensitive organisms were Daphnia pulex (EC50 = 0.32 mg/ml) and Tubifex tubifex (EC50 = 0.38 mg/ml), and the most resistant one was Chironomus aprilinus (EC50 = 0.83 mg/ml).

“…Patil et al (2012) determined that silver nanoparticles produced by Pergularia daemia are nontoxic to P. reticulata fish. Szymanski and Dobrucka (2022) evaluated the toxicity of certain particles and extracts produced with various solvents on Daphnia magna and Ceriodaphnia dubia. Following exposure to the produced extracts and generated nanosilver, no toxicity or adverse effects were identified.…”

Aims: Strawberry (Fragaria ananassa Duch.) is a member of the family Rosaceae and one of the most important vegetable crops in Egypt for local fresh consumption and exportation. Suspected symptoms of Strawberry mild yellow edge virus (SMYEV) on naturally infected strawberry plants were observed in Al Qaluobia Governorate. The main goal of this study was to develop a novel eco-friendly biogenic silver nanoparticle using clove (Syzygium aromaticum) (Sz-AgNPs) aqueous extract to control viral infection. Methodology and results: Mechanically inoculated sixteen plant species representing seven families, Apocynaceae, Chenopodiaceae, Cucurbitaceae, Fabaceae, Moraceae, Rosaceae and Solanaceae, were used as hosts for SMYEV. Systemic mosaic, chlorotic local lesions, vein clearing, marginal chlorosis, marginal necrosis, yellowing and vein banding were observed 7 to 20 days post-inoculation. Transmission electron microscopy (TEM) of diseased tissues revealed severe degeneration of the chloroplasts and nucleus structures and the formation of cell wall protrusions. Sz-AgNPs were characterized using UV-Vis spectroscopy, TEM, dynamic light scattering (DLS) and Fourier transform infrared (FTIR). Foliar application of Sz-AgNPs (200 µg/mL) 24 h post and/or concurrently with SMYEV inoculation dropped the infection rate by 90% and 55%, respectively, whereas it was only reduced by 35% when applied 24 h prior to viral inoculation compared to control groups. DAS-ELISA and RT-PCR verified SMYEV inhibition (75-90%) in all plants treated with 200, 150 and 100 µg/mL Sz-AgNPs 24 h post-viral inoculation. Complete viral eradication was attained by applying Sz-AgNPs at a concentration of 200 μg/mL 24 h post-virus inoculation. Moreover, the total phenols, indoles, Vitamin C, total flavonoids and citric acid contents were not significantly affected by Sz-AgNPs treatment compared to healthy control groups. Conclusion, significance and impact of study:In conclusion, Sz-AgNPs suppressed SMYEV by 75-90% when applied 24 h post-virus inoculation. Eco-friendly Sz-AgNPs could be used for controlling viral infections and avoiding the rejection of exportable strawberries due to the use of harmful pesticides.
