Abstract Development of efficient, stable, and recyclable photocatalysts for organic synthesis is vital transformation traditional thermal chemistry into green sustainable chemistry. In this work, the study reports an electrostatic approach to assemble meso‐tetra (4‐sulfonate phenyl) porphyrin (TPPS)tetra (TPPS) as a donor benzyl viologen (BV) acceptor stable photocatalyst efficient reaction – aryl sulfide oxidation. By use TPPS‐BV photocatalysts, 0.1 mmol with electron‐donating group can be completely transformed sulfoxide in 60 min without overoxidation sulfone, rendering near 100% yield selectivity. The recycled up 95% when 10 mg amount used. Mechanistic reveals that charge separation between TPPS BV results sufficient formation superoxide which further reacts oxidized by produce sulfoxide. This mechanistic pathway differs significantly from previously proposed singlet oxygen‐dominated process homogeneous photocatalysis.

Microplastics (< 5 mm) are a diverse class of contaminants ranging in morphology, polymer type, and chemical cocktail. Microplastic toxicity can be driven by one or combination these characteristics. Most studies, however, evaluate the physical effect most commercially available polymers. By disregarding other polymers with high consumption and/or production rates, constituents plastics, we fail to have holistic understanding mechanisms toxicity. Polyurethane is understudied terms effects testing yet considered hazardous due its composition. found common consumer products from packaging spray foam insulation. To better understand physico-chemical polyurethane additive products, exposed larval fathead minnows for 28 days without additives (i.e., plastic treatment), leachate containing tris(chloropropyl)phosphate [TCPP]; i.e., treatment) fully factorial experiment. We observed significant decreases growth at 12 posthatch (dph) plastic, chemical, treatments, suggesting driver At dph, did not observe differences growth, individuals recover. also concentrations ΣTCPPs minnow treatment only treatment, demonstrating TCPP uptake individuals. Combined, our data suggests importance both components microplastics when assessing effects, thus emphasizing need multidimensional way.

Exposure to organophosphate esters (OPEs) remains a significant concern, especially in aquatic systems where these compounds can bioaccumulate organisms. However, limited information exists regarding their potential health risks humans through the food web tropical ecosystems. This study investigated levels, bioaccumulation, and trophic transfer of OPEs sediments marine fish species from Cartagena Barbacoas bays, Colombia. Twenty target were quantified fish. The average concentrations ∑18OPEs ranged 2.80 115 ng/g dry weight (dw), while ∑20OPE 212 1968 lipid (lw), with highest found carnivorous species. Trophic magnification factors (TMF) for varied 11.0 25.8 such as 2-ethylhexyl diphenyl phosphate (EHDPP), 4-isopropylphenyl (4IPPDPP), tris(2-isopropylphenyl) (T2IPPP), tricresylphosphate (TCP), indicating biomagnification within web.

Despite findings, human risk OPE exposure via consumption was be minimal.

Fludioxonil is a widely used fungicide that frequently to combat fungal plant diseases. Consequently, excessive concentrations of fludioxonil may enter and accumulate over time in aquatic systems, harming (micro) organisms several ways. Thus, it great importance evaluate the potential toxic effects using bioassays. In present study, various vitro assays were assess possible human cells microorganisms. For investigation on freshwater microalgae, Scenedesmus rubescens Dunaliella tertiolecta exposed environmentally relevant for period 96 h. at 50–200 μg L−1 significantly limited growth both especially first 24 h exposure, where inhibitions up 82.34% calculated. The toxicity was further evaluated via Microtox test, studied found be less bacteria Aliivibrio fischeri. Regarding cells, fludioxonil’s cyto-genotoxic assessed Trypan blue exclusion test Cytokinesis Block MicroNucleus (CBMN) assay. Cell viability all fludioxonil-treated similar control values according results test. However, CBMN assay revealed had genotoxic higher exerted cytotoxic activity against lymphocytes. Specifically, only highest dose fludioxonil, i.e., 10 mL−1, lymphocytes, whereas treatment with 0.5, 1, 5 mL−1 did not lead statistically significant induction micronuclei (MN) frequencies compared culture. fludioxonil-mediated cytotoxicity significant, which demonstrated by decreased CBPI (cytokinesis block proliferation index) cases except lowest dose, 0.5 mL−1.
