Impact of Silver Nanoparticles on Wastewater Treatment

Destruction of Cell Topography, Morphology, Membrane, Inhibition of Respiration, Biofilm Formation, and Bioactive Molecule Production by Nanoparticles of Ag, ZnO, CuO, TiO2, and Al2O3 toward Beneficial Soil Bacteria

“…The NPs emerging from sources like industries, sewage wastes, wastewater treatment plants, tannery effluents, and other metal discharging industries are the major cause of nanopollution that adds considerable amounts of NPs to the terrestrial environment. 6,7 As per one estimate, up to 28% of total NPs production is expected to enter into terrestrial soils. 8 For instance, the consumption of silver (Ag) NPs and zinc oxide (ZnO) NPs in Europe per capita and their release has been significant, which is broadly distributed in the European territory.…”

“…Nanoparticles (NPs) generally defined as the particles ranging in size between 1 and 100 nm with multiple properties such as an extremely high surface-to-volume ratio, and specific surface area , NPs are being used in areas like agriculture, biomedical, pharmaceuticals, electronics, defense, and aerospace industries. − Among NPs, the production of metal and metal oxide NPs (MONPs) due to their wide range of end uses are likely to enhance their probability to enter the environment during the production, use, and disposal.

Elucidating the effect of TiO2 nanoparticles on mung bean rhizobia via in vitro assay: Influence on growth, morphology, and plant growth promoting traits

“…The NPs have applications in food and dairy industry, cosmetics, and agriculture with special emphasis on the use of NPs as nanofertilizers, nanocomposites, and nanopesticides [7][8][9][10]. The NPs released as effluents from various sources such as metal discharging industries [11], sewage [12], and wastewater treatment plants [13] contribute to nano-pollution in soil and water ecosystems. The engineered NPs exhibit peculiar properties and chemistry which make them act differently in the natural environments [14].…”
