MnFe layered double hydroxides confined MnO < sub > x < /sub > for peroxymonosulfate activation: A novel manner for the selective production of singlet oxygen
Environ Pollut. 2024 Mar 26:123865. doi: 10.1016/j.envpol.2024.123865. Online ahead of print.ABSTRACTSinglet oxygen (1O2) is a reactive species for the selective degradation of stubborn organic pollutants. Given its resistance to harsh water environment, the effective and exclusive generation of 1O2 is acknowledged as a key strategy to mitigate water production costs and ensure water supply safety. Herein, we synthesized MnOx intercalated MnFe layered double hydroxides (MF-MnOx) to selectively produce 1O2 through the activation of PMS. The distinctive confined structure endowed MF-MnOx with a special pathway for the PMS ac...

Optimizing a twin-chamber system for direct ozone production rate measurement
Environ Pollut. 2024 Mar 25:123837. doi: 10.1016/j.envpol.2024.123837. Online ahead of print.ABSTRACTHigh Ozone Production Rate (OPR) leads to O3 pollution episodes and adverse human health outcomes. OPR observation (Obs-OPR) and OPR modelling (Mod-OPR) have been obtained from observed and modelled peroxy radicals and nitrogen oxides. However, discrepancies between them remind of an imperfect understanding of O3 photochemistry. Direct measurement of OPR (Mea-OPR) by a twin-chamber system emerges. Herein, we optimized Mea-OPR design, i.e., minimizing the chamber surface area to volume ratio (S/V) to 9.8 m-1 from 18 m-1 and ...

Unraveling the spectral and biochemical response of mangroves to oil spills and biotic stressors
This study reveals strong intra- and interspecific variability of mangrove's spectral and biochemical responses to oil pollution. Trees undergoing acute exposure to oil showed stronger alterations of foliar traits than the chronically exposed ones. Alterations induced by biotic stressors such as parasitism, disease, and grazing were successfully discriminated from those of oil for all species based on Linear Discriminant Analysis (Overall Accuracy ≥76.40% and Kappa ≥0.70). Leaf chlorophyll, phenol, and starch contents were identified as the most relevant traits in stressor discrimination. The study highlights that oil ...

In vitro blastocyst implantation and trophoblast migration are disrupted by the UV filter benzophenone-3 (BP3)
Environ Pollut. 2024 Mar 25:123840. doi: 10.1016/j.envpol.2024.123840. Online ahead of print.ABSTRACTBenzophenone-3 (BP3) is a common ingredient in personal care products (PCPs) due to its well-established effectiveness in absorbing UV radiation. Sunscreen products are among the most widely used PCPs-containing BP3 applied to the skin, resulting in significant human exposure to BP3 primarily through a dermal application. In the present work, we have tested the action of three environmentally relevant concentrations of BP3 (2, 20 and 200 μg/L) on an in vitro model of implantation of murine blastocysts and on migration abil...

Birds as bioindicators of plastic pollution in terrestrial and freshwater environments: A 30-year review
Environ Pollut. 2024 Mar 25:123790. doi: 10.1016/j.envpol.2024.123790. Online ahead of print.ABSTRACTPlastic pollution is a global concern that has grown ever more acute in recent years. Most research has focused on the impact of plastic pollution in marine environments. However, plastic is increasingly being detected in terrestrial and freshwater environments with key inland sources including landfills, where it is accessible to a wide range of organisms. Birds are effective bioindicators of pollutants for many reasons, including their high mobility and high intra- and interspecific variation in trophic levels. Freshwater...

Mechanical energy triggered piezo-catalyzation of Bi < sub > 2 < /sub > WO < sub > 6 < /sub > nanoplates on ferrate (Fe(VI)) oxidation in alkaline media: Performance and mechanism
Environ Pollut. 2024 Mar 25;348:123862. doi: 10.1016/j.envpol.2024.123862. Online ahead of print.ABSTRACTPiezo-electricity, as a unique physical phenomenon, demonstrates high effectiveness in capturing the environmental mechanical energy into polarization charges, offering the possibility to activate the advanced oxidation processes via the electron pathway. However, information regarding the intensification of Fe(VI) through piezo-catalysis is limited. Therefore, our study is the first to apply Bi2WO6 nanoplates for piezo-catalyzation of Fe(VI) to enhance bisphenol A (BPA) degradation. Compared to Fe(VI) alone, the Fe(VI)...
