“…Furthermore, nanoremediation is a sustainable alternative to eliminate emerging pollutants such as pharmaceutics or personal care products . Several studies have been published on soil nanoremediation (Table 2), whereas there are few studies on nanopollutants (e.g., Ahmed et al 2021b;Antuña et al 2022;Das et al 2022). Several technologies can be applied for soil remediation of heavy metals and other pollutants, including physical remediation (e.g., soil thermal desorption and soil replacement), chemical remediation (e.g., chemical leaching, chemical stabilization, electrokinetic remediation-permeable reactive barrier, and chemical oxidation/reduction), bioremediation including phytoremediation and microbial remediation (Song et al 2022), as well nanoremediation (Table 2) and various combined remediation methods.…”

NVIRONMENTAL pollution is a great modern challenge. This pollution is generated from different sources and reaches a variety of environmental compartments including soil, water, plants, air, animals, and humans. Among sources of pollution, nanopollution has become an emerging global issue. Nanopollution is a result of the intensive processing and use of nanomaterials and/or nanoparticles in the soil, water, plant, air, and food chain systems. Ultimately, nanopollutants may reach humans and influence their health. Health problems reported after human exposure to nanopollutants include toxicity to the kidney, brain, spleen, and heart. Approaches to remediate soil nanopollution will be discussed in this review, which focuses on soil nanopollution in the frame of soil-human health nexus (SHHN). A close relationship between soil nanopollution and the SHHN has been confirmed by several studies. This interaction depends on several factors related to the pollutants, their concertation, and agro-environmental conditions. The interaction between soil nanopollutants and human health is of great concern and needs more study.

Investigating the ternary relationship among nanoparticles (NPs), their immediate molecular environment, and test organisms rather than the direct interaction between pristine NPs and test organisms has been thrust into the mainstream of nanotoxicological research. Diverging from previous work that predominantly centered on surrounding molecules affecting the toxicity of NPs by modulating their nanoproperties, this study has unveiled a novel dimension: surrounding molecules altering bacterial susceptibility to NPs, consequently impacting the outcomes of nanobio interaction. The study found that adding nitrate as the surrounding molecules could alter bacterial respiratory pathways, resulting in an enhanced reduction of ceria NPs (nanoceria) on the bacterial surfaces. This, in turn, increased the ion-specific toxicity originating from the release of Ce 3+ ions at the nanobio interface. Further transcriptome analysis revealed more mechanistic details underlying the nitrate-induced changes in the bacterial energy metabolism and subsequent toxicity patterns. These findings offer a new perspective for the deconstruction of nanobio interactions and contribute to a more comprehensive understanding of NPs' environmental fate and ecotoxicity.

“…Moreover, the use of nanoparticles (NPs) as nanofertilizers for targeted delivery of micronutrients is considered as efficient, cost-effective, eco-friendly, and best alternatives to chemical fertilizers ( Irshad et al, 2021b ; Shah et al, 2021 ). In the last few years, several methods, such as physical (electro-explosion, gamma radiations, pulse laser ablation, ion sputtering scattering, mechanical/ball milling), chemical (sol–gel, microemulsion, co-precipitation, hydrothermal) and biological approaches (using microorganisms/plants extracts), have been used for the production of metallic NPs ( Ahmed et al, 2021d ; Noman et al, 2022 ). Various studies have reported the application of NPs improved the abiotic stress tolerance in plants by modulating the biochemical, morpho-physiological and genetic mechanisms under salinity stress ( Rossi et al, 2017 ), drought stress ( Mozafari et al, 2018 ), and HMs stress ( Bashir et al, 2020 ).…”

Abiotic stresses, such as heavy metals (HMs), drought, salinity and water logging, are the foremost limiting factors that adversely affect the plant growth and crop productivity worldwide. The plants respond to such stresses by activating a series of intricate mechanisms that subsequently alter the morpho-physiological and biochemical processes. Over the past few decades, abiotic stresses in plants have been managed through marker-assisted breeding, conventional breeding, and genetic engineering approaches. With technological advancement, efficient strategies are required to cope with the harmful effects of abiotic environmental constraints to develop sustainable agriculture systems of crop production. Recently, nanotechnology has emerged as an attractive area of study with potential applications in the agricultural science, including mitigating the impacts of climate change, increasing nutrient utilization efficiency and abiotic stress management. Nanoparticles (NPs), as nanofertilizers, have gained significant attention due to their high surface area to volume ratio, eco-friendly nature, low cost, unique physicochemical properties, and improved plant productivity. Several studies have revealed the potential role of NPs in abiotic stress management. This review aims to emphasize the role of NPs in managing abiotic stresses and growth promotion to develop a cost-effective and environment friendly strategy for the future agricultural sustainability.
