The safe implementation of nanotechnology requires nanomaterial hazard assessment in accordance with the material physicochemical properties that trigger injury response at nano/bio interface. Since CuO nanoparticles (NPs) are widely used industrially and their dissolution play a major role potential, we hypothesized tighter bonding Cu to Fe by particle doping could constitute safer-by-design approach through decreased dissolution. Accordingly, designed combinatorial library which was doped...

The role of Pt on photocatalytic substrates such as TiO2 (P25) for the decomposition organic pollutants is still controversial in scientific community. well-observed behavior an optimum catalytic activity a function loading usually explained by shift from charge separation to recombination clusters. However, experiments supporting this explanation are lacking give concise understanding effect activity. Here, we present experimental study that tries discriminate different effects influencing...
Abstract Since 2015, the determination of microplastics (MPs; < 5 mm) in soil has gained increasing attention. However, usual analytical protocols still render a comparison results challenging. This structured review integrates an in-depth screening scientific articles ( n = 106; from 1980 to 2022) that focused on determining MPs soils. The different studies were divided into groups regarding (i) input pathways, (ii) study site information, (iii) sampling design, (iv) sample preparation,...
The present study deals with the primary biodegradability of ionic liquids in order to obtain a greater insight into their fate under different environmental conditions. focus was thereby on biodegradation potential liquid anions when undergoing aerobic and anaerobic biological waste water treatment. Five technologically relevant fluoroorganic cyano-based were investigated as alkaline salts (Li (CF3SO2)2N, K (C2F5)3PF3 Na N(CN)2, C(CN)3, B(CN)4 respectively). Their determined activated...
Iron oxide nanoparticles (IONP) are currently being studied as green magnet resonance imaging (MRI) contrast agents. They also used in huge quantities for environmental remediation and water treatment purposes, although very little is known on the consequences of such applications organisms ecosystems. In order to address these questions, we synthesised polyvinylpyrrolidone-coated IONP, characterised particle dispersion various media investigated an IONP exposure using array biochemical...
Silver nanoparticles (AgNP) are integrated into various products due to their antimicrobial characteristics and hence, the application of AgNP is increasing. During production, use disposal emitted enter environment via several pathways. Soils considered a major sink AgNP. The aim present study was determine toxic effect on Folsomia candida reproduction illustrate potential impact terrestrial ecosystems. AgNP-dependent reduction F. studied in RefeSol 01-A, LUFA 2.2 OECD soil at 0.3 µg – 50...
Silver nanoparticles (AgNPs) are widely applied for their antibacterial activity. Their increasing use in consumer products implies that they will find way into the environment via wastewater-treatment plants. The aim of present study was to compare ecotoxicological impact 2 differently designed AgNPs using solid contact test bacterial strain Arthrobacter globiformis. In addition, a miniaturized version this system established, which requires only small-sized samples because produced small...
There is a lack of knowledge about the fate and impact microplastics (MPs) nanoplastics (NPs), as well their potential uptake on plants microorganisms. The predicted environmental concentrations (PEC) frequent polymers in soils are low, therefore, difficult to detect with available techniques, which explains gaps. Therefore, model particles (polystyrene (PS-P), 343 nm) palladium (Pd) nanoparticle-doped polystyrene (PS-Pd-PS-P, 442 were synthesized, characterized, subsequently applied...
