Impact of airborne iron oxide nanoparticles on Tillandsia usneoides as a model plant to assess pollution in heavy traffic areas
Chemosphere. 2024 Mar 24:141765. doi: 10.1016/j.chemosphere.2024.141765. Online ahead of print.ABSTRACTDue to the increasing evidence of widespread sub-micron pollutants in the atmosphere, the impact of airborne nanoparticles is a subject of great relevance. In particular, the smallest particles are considered the most active and dangerous, having a higher surface/volume ratio. Here we tested the effect of iron oxide (Fe3O4) nanoparticles (IONPs) with different mean diameter and size distribution on the model plant Tillandsia usneoides. Strands were placed in home-built closed boxes and exposed to levels of airborne IONPs ...

Efficacy of exopolysaccharide in dye-laden wastewater treatment: A comprehensive review
Chemosphere. 2024 Mar 24:141753. doi: 10.1016/j.chemosphere.2024.141753. Online ahead of print.ABSTRACTThe discharge of dye-laden wastewater into the water streams causes severe water and soil pollution, which poses a global threat to aquatic ecosystems and humans. A diverse array of microorganisms such as bacteria, fungi, and algae produce exopolysaccharides (EPS) of different compositions and exhibit great bioflocculation potency to sustainably eradicate dyes from water bodies. Nanomodified chemical composites of EPS enable their recyclability during dye-laden wastewater treatment. Nevertheless, the selection of potent E...

Accelerator mass spectrometry measurements of < sup > 233 < /sup > U in groundwater, soil and vegetation at a legacy radioactive waste site
Chemosphere. 2024 Mar 24:141761. doi: 10.1016/j.chemosphere.2024.141761. Online ahead of print.ABSTRACTLow-level radioactive wastes were disposed at the Little Forest Legacy Site (LFLS) near Sydney, Australia between 1960 and 1968. According to the disposal records, 233U contributes a significant portion of the inventory of actinide activity buried in the LFLS trenches. Although the presence of 233U in environmental samples from LFLS has been previously inferred from alpha-spectrometry measurements, it has been difficult to quantify because the 233U and 234U α-peaks are superimposed. Therefore, the amounts of 233U in grou...

Effects of root-derived organic acids on sorption of pharmaceutically active compounds in sandy topsoil
Chemosphere. 2024 Mar 24:141759. doi: 10.1016/j.chemosphere.2024.141759. Online ahead of print.ABSTRACTThe presence and fate of pharmaceutically active compounds (PhACs) in agricultural fields are rarely investigated. The present study highlights that root-derived low-molecular-weight organic acids (LWMOAs) affect the mobility of PhACs in cultivated humic Arenosol. Sorption experiments are conducted using three PhACs characterised by different physicochemical properties: carbamazepine (CBZ), 17α-ethinylestradiol (EE2), and diclofenac-sodium (DFC). The results suggest that the adsorption of EE2 is more intense than the oth...

Development of persulfate-based advanced oxidation processes to remove synthetic azo dyes from aqueous matrices
Chemosphere. 2024 Mar 23:141766. doi: 10.1016/j.chemosphere.2024.141766. Online ahead of print.ABSTRACTAzo dyes are largely used in many industries and discharged in large volumes of their effluents into the aquatic environment giving rise to non-esthetic pollution and health-risk problems. Due to the high stability of azo dyes in ambient conditions, they cannot be abated in conventional wastewater treatment plants. Over the last fifteen years, the decontamination of dyeing effluents by persulfate (PS)-based advanced oxidation processes (AOPs) has received a great attention. In these methods, PS is activated to be decompos...

Sustainable removal of caffeine and acetaminophen from water using biomass waste-derived activated carbon: Synthesis, characterization, and modelling
Chemosphere. 2024 Mar 23:141787. doi: 10.1016/j.chemosphere.2024.141787. Online ahead of print.ABSTRACTThe removal of caffeine (CFN) and acetaminophen (ACT) from water using low-cost activated carbons prepared from artichoke leaves (AAC) and pomegranate peels (PAC) was reported in this paper. These activated carbons were characterized using various analytical techniques. The results showed that AAC and PAC had surface areas of 1203 and 1095 m2 g-1, respectively. The prepared adsorbents were tested for the adsorption of these pharmaceuticals in single and binary solutions. These experiments were performed under different op...

Differential intestinal effects of water and foodborne exposures of nano-TiO < sub > 2 < /sub > in the mussel Mytilus coruscus under elevated temperature
Chemosphere. 2024 Mar 23:141777. doi: 10.1016/j.chemosphere.2024.141777. Online ahead of print.ABSTRACTWith the wide use of nanomaterials in daily life, nano-titanium dioxide (nano-TiO2) presents potential ecological risks to marine ecosystems, which can be exacerbated by ocean warming (OW). However, most previous studies have only centered around waterborne exposure, while there is a scarcity of studies concentrating on the impact of trophic transfer exposure on organisms.

Unveiling the detrimental effects of polylactic acid microplastics on rice seedlings and soil health
This study aimed to assess the repercussions of varying concentrations of PLA-MPs on rice, encompassing aspects such as growth, physiology, and biochemistry. Additionally, the investigation delved into the influence of PLA-MPs on soil bacterial composition and soil enzyme activities. The results illustrated that the highest levels of PLA-MPs (2.5%) impaired the photosynthesis activity of rice plants and hampered plant growth. Plants exposed to the highest concentration of PLA-MPs (2.5%) displayed a significant reduction of 51.3% and 47.7% in their root and shoot dry weights, as well as a reduction of 53% and 49% in chlorop...

Synergistic activation of lamellar bismuth selenide anchored functionalized carbon nanofiber for detecting hazardous carbendazim in environmental water samples
Chemosphere. 2024 Mar 22:141744. doi: 10.1016/j.chemosphere.2024.141744. Online ahead of print.ABSTRACTPesticides pollute natural water reservoirs through persistent accumulation. Therefore, their toxicity and degradability are serious issues. Carbendazim (CBZ) is a pesticide used against fungal infections in agricultural crops, and its overexploitation detrimentally affects aquatic ecosystems and organisms. It is necessary to design a logical, efficient, and field-deployable method for monitoring the amount of CBZ in environmental samples. Herein, a nano-engineered bismuth selenide (Bi2Se3)/functionalized carbon nanofiber...
