However, for hair, there are few studies indicating the safety of using ozone gas, especially when in contact with hair fiber. The aim of this study was to characterize possible physicochemical changes that may occur in hair strands exposed to ozone gas. Scanning electron microscopy (SEM) and profilometry for surface analysis, Fourier transform infrared spectroscopy (FTIR) with attenuated total reflection (ATR) for chemical analysis, Thermogravimetry, and grazing incidence X-ray diffraction (GIXRD) for structural analysis were used. SEM and profilometry techniques showed evidence of changes in appearance of the hair fiber. While FTIR-ATR showed degradation of characteristic peaks on the hair infrared spectrum, with major changes at peaks 2920, 2851, 1633, 1235, 1075, and 1043 cm−1, also associated with the cuticle and mainly related to the cell membrane complex (CMC). Thermogravimetry and GIXRD have shown the possible effect of ozone on human hair amino acids. The results obtained indicated that ozone gas applied on human hair showed oxidative action. Therefore, additional studies are required before discussing the replacement of PCPs by gas ozone.KEYWORDS: Amino acidsHuman hairOxidationOzonePersonal care products (PCPs) AcknowledgmentsWe thank Laboratório de Plasmas e Processos from Instituto Tecnológico de Aeronáutica, Brazil, for providing the analysis on the equipment Frontier infrared spectrometer and PANalytical Empyrean.P.

However, PV methodology has been adapted from vegetable oils, with protocol divergences. In addition, few studies are based on the minimum level of ozonation to ensure biological activity. This study aimed to optimize the PV methodology for sunflower oil with different ozone dosage aiming to discriminate these samples. Also, to establish the relationship between its physicochemical properties with the biological activity. The optimized PV method was also applied to ozonated olive oil, as well as the other analytical techniques of iodine value (IV), acidity value (AV), density, viscosity, gas chromatography, infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), differential scanning calorimetry and thermogravimetry (DSC and TG). The PV method discriminated the ozonation level of the samples. Both ozonated sunflower and olive oils need to reach an intermediary ozone dosage to perform the in vitro bactericidal and fungicidal activity (MIC ≤2.5%), and anti-inflammatory activity (inhibition of nitric oxide release in Raw cells). These results point to the importance of standardizing the ozone dosage for each oil and the analytical methodologies used in its characterization.KEYWORDS: Anti-inflammatory activityantimicrobial activityozonated oilquality control Disclosure statementNo potential conflict of interest was reported by the authors.Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/01919512.2023.2266734Additional informationFundingThe authors are grateful to FAPESC (Support Foundation for Research and Innovation of the State of Santa Catarina), (grant 2021TR1823 and 2021TR1241), CNPq (National Council for Scientific and Technological Development, Edital nº 4/2021, grant 304799/2021-1-TMBB; 310326/2020-6-JRS; 305768/2021-2-RAF; 310804/2020-5-AM), for the financial support, and to Philozon (Balneário Camboriú, SC, Brazil) by GSJ scholarship and for the donation of samples.","PeriodicalId":19580,"journal":{"name":"Ozone: Science & Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136142630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, the combined VUV/O3 process provided the greatest MC-LR removal, with the presence of chloride enhancing the removal efficacy. Formation of chlorine radical species was the primary reason for the observed improvement. The order of MC-LR removal by different processes using UV fluence of around 300 mJ cm−2, ozone dose of 0.1 mg L−1, and chloride concentration of 120 mg L−1 was as follows: VUV/O3/Chloride > VUV/O3 > VUV/Chloride > VUV > O3. Comparing MC-LR removal by O3, VUV and VUV/O3 in synthetic lab samples, spiked with Suwannee River NOM and natural water samples of the same organic concentration, showed the significance of background organics in scavenging ozone in the process. For a given ozone dosage, MC-LR removal by O3 or VUV/O3 in natural water was lower than that in the synthetic water samples. The standalone VUV was not affected and the MC-LR removals were identical in both synthetic and natural waters.KEYWORDS: Advanced oxidationchloride enhancementmicrocystin-LR degradationOzoneSuwannee River NOMvacuum ultraviolet AcknowledgmentsThis study was funded by Qatar National Research Fund (QNRF) while the experiments were conducted in the laboratories of the Chemical and Biological Engineering Department at the University of British Columbia.

However, high salinity has a negative impact on catalytic ozonation performance. In this work, tin oxide (SnOx) and manganese oxide (MnOx) doped γ-Al2O3 catalysts (SnOx-MnOx@Al2O3) were prepared by the incipient wetness impregnation method and characterized by SEM, XRD, BET, XRT, XPS and FT-IR techniques. The SnOx-MnOx@Al2O3 catalyst was applied to the catalytic ozonation of phenol in hypersaline wastewater, and the catalytic performance was evaluated by COD removal efficiency. When the mass ratio of MnOx to SnOx was 1:3, the pH was 7, the catalyst dosage was 40 g/L, the ozone dosage was 6 mg/(L·min), the NaCl concentration was 15 g/L and the COD removal efficiency of hypersaline phenol wastewater reached 93.8% after 240 min of catalytic ozonation treatment. Compared with the single ozonation process (SOP), the introduction of SnOx-MnOx@Al2O3 catalyst improved the COD removal efficiency by 32.3%. Cl− may quench surface •OH species and ozone to form Cl• and Cl2•− with low activity and high selectivity, resulting in the reduction of catalytic ozonation efficiency. The catalytic activity of the SnOx-MnOx@Al2O3 catalyst remained high after eight cycles. In conclusion, the SnOx-MnOx@Al2O3 catalytic ozonation system exhibits efficient and stable mineralization performance and is a promising strategy for the treatment of hypersaline organic wastewater.","PeriodicalId":19580,"journal":{"name":"Ozone: Science & Engineering","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88415230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, non-thermal treatments are preferred to ensure safe food while preserving food quality. High voltage atmospheric cold plasma (HVACP) is a novel non-thermal technology with the potential to reduce contaminants (e.g. mycotoxins) owing to reactive species such as ozone. Therefore, the aim of this study was to investigate the efficacy of HVACP to degrade Aflatoxin M1 (AFM1) in pure water. A dielectric barrier discharge HVACP was performed at 90 kV using modified air (MA65: 65% O2, 30% CO2, 5% N2) fill gas for 1, 3, and 5 min in a direct and indirect mode with no post-treatment or 4.0 h post-storage at room temperature. The chemical properties of water were evaluated. Ozone concentration in both gas and liquid phases was also measured. A 77% reduction of AFM1 was observed after 1 min of direct treatment with no post-treatment storage. The nitrate and peroxide contents after 1 min of direct treatment were 4.50 ± 0.70 and 9.5 ± 0.70 mg/L, respectively. Longer treatment time and direct mode of exposure resulted in a higher ozone concentration in either the gas or liquid phase. These results demonstrate the potential of HVACP as a non-thermal treatment for reducing AFM1 concentration. HVACP was capable of significantly degrading AFM1 using a very short treatment time and 4.0-h post-treatment storage.","PeriodicalId":19580,"journal":{"name":"Ozone: Science & Engineering","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90533022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine the lethal effect of a minimum dose and time combination on insects, the potential effect on insect spiracles and cuticles, as well as technological properties of wheat flour. At various exposure durations, ozone concentrations of 0.428 g/m3 (200 ppm) were used for 2, 4, and 6 h. Ozone gas was administered to the eggs, larvae, and adults of Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) and Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). For R. dominica, adults were significantly more resistant to ozone gas than the larval and egg stages. For T. castaneum, adults and larvae seem to have a similar ozone susceptibility, and both were more resistant than eggs. This resistance was largely dependent on the insect species and exposure duration. The scanning electron microscope (SEM) showed multi-action on the cuticle, spiracles, and antennae of the insects treated by ozone. Wheat flour exracted from grains exposed to 0.428 g/m3 ozone for 6 h was subjected to further physiochemical analysis. Germination of ozone-treated wheat grains was 77%, compared to 83% of the untreated ones. The chlorophyll content of treated and untreated grains was 1.65 and 1.07 mg/g, respectively. The protein, fat, fiber, ash, and total carbohydrate contents of the ozone-treated samples (wholemeal and flour) did not differ significantly compared to the control. The rheological properties of wheat flour showed that ozone significantly decreased its water absorption (WA) from 56.21 to 55.81% while increasing dough development time (DDT) and dough stability time (DST). All sensorial parameters did not differ significantly between ozone-treated and untreated samples. Pan bread made from the flour of ozone-treated grains was fresher than the control bread.","PeriodicalId":19580,"journal":{"name":"Ozone: Science & Engineering","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81887416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
