Assessment of the toxicity of silicon nanooxide in relation to various components of the agroecosystem under the conditions of the model experiment

Silicon-based nanoparticles for mitigating the effect of potentially toxic elements and plant stress in agroecosystems: A sustainable pathway towards food security

Due to their size, flexibility, biocompatibility, large surface area, and variable functionality nanoparticles have enormous industrial, agricultural, pharmaceutical and biotechnological applications. This has led to their widespread use in various fields. The advancement of knowledge in this field of research has altered our way of life from medicine to agriculture. One of the rungs of this revolution, which has somewhat reduced the harmful consequences, is nanotechnology. A helpful ingredient for plants, silicon (Si), is well-known for its preventive properties under adverse environmental conditions. Several studies have shown how biogenic silica helps plants recover from biotic and abiotic stressors. The majority of research have demonstrated the benefits of silicon-based nanoparticles (Si-NPs) for plant growth and development, particularly under stressful environments. In order to minimize the release of brine, heavy metals, and radioactive chemicals into water, remove metals, non-metals, and radioactive components, and purify water, silica has also been used in environmental remediation. Potentially toxic elements (PTEs) have become a huge threat to food security through their negative impact on agroecosystem. Si-NPs have the potentials to remove PTEs from agroecosystem and promote food security via the promotion of plant growth and development. In this review, we have outlined the various sources and ecotoxicological consequences of PTEs in agroecosystems. The potentials of Si-NPs in mitigating PTEs were extensively discussed and other applications of Si-NPs in agriculture to foster food security were also highlighted.

Study of effects of metallic nanoparticles when introduced into soil on plant Triticum vulgare

We studied the effect of metal nanoparticles (Fe, Mo and SiO2, and also Fe and Mo together) at concentration of 10, 25 and 50 mg/kg dry weight of soil on the morphological and biochemical parameters of soft wheat. (Triticum vulgare Vill). We found that morphometric parameters of test samples were generally superior to control samples. In course of assessing the viability of plant cells, we recorded that experimental groups had viability values of at least 90%. Thus, it allowed us to conclude that the concentrations of nanoparticles used by us did not have a toxic effect on the viability of the roots. When evaluating the enzymatic antioxidant system of plants and the degree of lipid peroxidation, we noted the absence of oxidative stress, while increasing the protective potential of plants. Thus, our studies are the basis for studying the possibility of using nanoparticles in agriculture for intensifying plant growth and increasing their yield.
