Distributions on per-cigarette basis concentrations of these metals, as determined by graphite furnace atomic absorption spectrometry, were used as inputs in the probabilistic risk assessment. The contents of these metals in cigarettes varied significantly. Larger quantities of the studied metals were observed in regular cigarettes than in slim cigarettes, but the concentration levels per cigarette tobacco mass were higher in slim cigarettes. The metal concentrations in counterfeit cigarettes were marginally higher than those in authentic brands. Based on the mean concentrations, Pb was the most abundant toxic metal, followed by Ni and Cd. The calculated values of the cumulative hazard index (HI) and incremental lifetime cancer risk (ILCR) indicated a low noncarcinogenic risk and low but not negligible carcinogenic risk from Cd, Pb, and Ni. The mean HI and ILCR values obtained using probabilistic and deterministic approaches were similar. A Monte Carlo simulation was employed to minimize the uncertainty of health risk estimation. The sensitivity analysis revealed that the most influential factor was cigarette mass followed by Cd content.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"23 1","pages":"92 - 110"},"PeriodicalIF":0.0,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87271194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To eliminate sewage and wastewater treatment plants as entry pathways, advanced oxidation processes have been intensely researched. Hence, photolysis at different pH ranges was studied for its capacity to eradicate ciprofloxacin. High-performance liquid chromatography coupled to high-resolution mass spectrometry was used to identify the degradation products and to monitor all compounds. Ecotoxicity was assessed using quantitative structure-activity relationship analysis comprising the Ecological Structure Activity Relationships tool. Two degradation mechanisms were found active: the direct mechanism, i.e. degradation through ultraviolet absorption by the substance, and the indirect mechanism caused by hydroxyl radicals from water photolysis. The radical scavenger tert-butanol and pH variations revealed that the indirect mechanism predominated in general. The direct photo-induced degradation proceeded about 10 times slower. Products could be attributed to the mechanisms. Based on their chemical structures, all identified products were predicted less toxic by quantitative structure-activity relationship than ciprofloxacin. Mechanistic insight suggested that photo-induced advanced oxidation processes proved efficient for ciprofloxacin elimination when generating hydroxyl radicals. Compounds and pH range hampering their occurrence diminish the efficacy of elimination.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"22 1","pages":"1 - 18"},"PeriodicalIF":0.0,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85882719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glutathione reductase, glutathione peroxidase, and glutathione S-transferase gene expression levels were up-regulated on day 1 and then down-regulated following exposure to 5 mg/L perfluorooctane sulfonate with those of the control. The activities of the three corresponding enzymes were inhibited by perfluorooctane sulfonate and activated by anthocyanins.

Two-dimensional g-C3N4 nanosheets were coupled with TiO2 hollow spheres at different ratios to investigate the charge-carrier interactions with the aim of enhancing the photocatalytic properties of the nanocomposite. This coupling was systematically examined by scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, photoluminescence, X-ray photoelectron spectroscopy, and UV diffuse reflectance spectroscopy. The prepared nanocomposite was used for the photodegradation of the volatile organic carbons methyl tetra-butyl ether and toluene present in aqueous solution. Elemental analysis and X-ray diffraction revealed a high-purity sample, while the UV diffuse reflectance spectroscopy demonstrated the presence of a well-defined anatase crystal phase for the TiO2 hollow sphere; and the photoluminescence measurements showed an enhancement in visible-light absorbance, with a good reduction in the electron-hole recombination rate. The performance of the nanocomposites in the photocatalytic degradation of toluene under irradiation with visible-light was evaluated. The 20/80% TiO2/g-C3N4 nanocomposite materials showed highest photocatalytic activity for toluene and methyl tetra-butyl ether, achieving a degradation of more than 90%; this is attributed to the interaction between the two surfaces in the TiO2/g-C3N4 nanocomposite, resulting in a higher performance than the individual components.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"58 1","pages":"211 - 231"},"PeriodicalIF":0.0,"publicationDate":"2022-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87487686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of annealing temperature on the crystal structure, phase composition, morphology, surface area, surface functional groups, and surface atomic composition of the prepared catalysts were investigated by powder X-ray diffraction, field emission scanning electron microscope, nitrogen adsorption-desorption, Fourier transform infrared spectroscopy, and low voltage energy-dispersive X-ray spectroscopy. The catalytic activity was evaluated via the degradation of methylene blue in the presence of oxalic acid under UVA light and visible light. Immobilization of Fe2O3 on the perlite surface resulted in photo-Fenton catalytic activity for all samples, attributable to the formation of the hematite phase and the presence of surface Fe species. Owing to the low density of perlite, all catalysts float on the surface of the solution, which allows them to be easily separated.
