In this study, ammonium dihydrogen phosphate (ADP) was selected as the inhibitor to inhibit the PCDD/F formation via de novo synthesis at 350 °C. The influence of oxygen content and addition method on PCDD/F inhibition was systematically investigated by means of statistical analysis and morphological characterization. The results showed that oxygen enhanced the formation of PCDD/Fs from 1470 ng g⁻¹ (9.78 ng I-TEQ g⁻¹) to 2110 ng g⁻¹ (14.8 ng I-TEQ g⁻¹). ADP significantly inhibited the PCDD/F formation, with inhibition efficiencies ranging from 82.0% to 97.7%. Herein, a higher oxygen content and the premixed way intensified the suppression effect. Dibenzo-<i>p</i>-dioxin (DD)/dibenzofuran (DF) chlorination was proven to be effectively suppressed while chlorophenol (CP) route was not obviously influenced. With the addition of ADP, Cl source was significantly reduced and the formation of organic Cl was effectively inhibited. Also, it decreased the proportion of C–O/C=N and C=O, revealing the efficient inhibition of carbon oxidation. Meanwhile, the formation of copper phosphate and copper pyrophosphate was observed in XPS (X-ray photoelectron spectroscopy) spectra, indicating that the catalytic metal Cu was chelated and passivated by ADP. The premixed way had a better effect on reducing Cl resources, inhibiting oxidation and chelating metals, due to the direct contact with inhibitor. However, the separation method could only depend on the decomposed gases, resulting in a lower inhibition efficiency.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":807,"journal":{"name":"Waste Disposal & Sustainable Energy","volume":"6 1","pages":"11 - 24"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134902143","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}

In this study, zinc oxide nanoparticles (ZnO-NPs) were biosynthesized using the aqueous extract of <i>Dunaliella</i> sp. and immobilized on PET/C waste fabrics after enzymatically activated with cellulases. The produced <i>Dunaliella</i>-ZnO-NPs (10–20 nm with a spherical shape) were characterized by High-resolution transmission electron microscopy (HRTEM), Fourier-transform infrared spectroscopy (FTIR), X-Ray diffraction analysis (XRD), and Scanning electron microscopy-energy dispersive X-ray analyzer (SEM-EDAX), and some functional groups, such as CH, CO, NH, and CN (due to the presence of carboxyl, proteins and hydroxyl groups), were detected, revealing the biosynthesis of ZnO-NPs. The analysis showed that the resulting ZnO-NPS had potent antimicrobial effects, Ultraviolet (UV) protection capabilities, and no cytotoxic effects on the normal human fibroblast cell line (BJ1). On the other hand, enzymatic treatments of PET/C fabric waste with cellulases enhanced the immobilization of biosynthetic nanoparticles on their surface. Modified PET/C fabrics loaded with <i>Dunaliella</i>-ZnO-NPs showed antibacterial and UV protection capabilities making them an eco-friendly and cost-effective candidate for numerous applications.

Receptor-based data analysis techniques help in comprehending local ozone fluctuations in the lack of accurate information on the emission characteristics. Through sophisticated data analysis, the current study offers insight into the key factors influencing the ozone changes in the vicinity of power plants. Ground ozone (O₃) and its precursor variables carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO₂), Sulphur dioxide (SO₂), benzene, toluene, ethyl-benzene and xylene (BTEX) along with the particulate matter of size less than 10 and 2.5 micron (PM₁₀ and PM_2.5) and meteorological variables have been studied at a residential site near the coal-fired power plant in the two cities; Chandrapur and Nagpur during 2016–2019. O₃ is observed to be not correlated significantly (<i>r</i>&lt;0.16 and &lt;0.1 in Nagpur and Chandrapur, respectively) with any of its precursor variables in two cities. On a finer time scale, however, an association of O₃ with CO, NO, NO₂ and BTEX suggested that the O₃ formation mechanism is driven by volatile organic compounds (VOCs) (mainly BTEX), CO and NO_x. On the coarser scale, however, seasonality and other factors have distorted the correlation. Random forest model with O₃ concentration as the response variable and NO₂, NO, SO₂, CO, BTEX, PM₁₀ and PM_2.5 as independent variables suggested that PM₁₀, NO, CO and solar radiation are highly important variables governing the O₃ dynamics in Chandrapur. In Nagpur, wind direction, relative humidity, temperature, toluene and NO₂ are more important. Qualitative analysis to assess the contribution of emission sources suggested the influence of traffic emissions in Nagpur and the dominance of non-traffic related emissions, mainly power plant and mining activities in Chandrapur.

Continuous rainfall releases soluble salts from the bottom ash subgrade into the surrounding soil and groundwater, resulting in potential hazards. Different methods were employed to simulate and collect runoff water during rainfall events, including batch leaching test, dynamic leaching test and constant head test, to assess environmental impact of bottom ash as road basement materials under continuous rainfall conditions. This study simulated the seepage of bottom ash backfill roads under different rainfall intensities, rainfall times, and rainfall pH values. A comprehensive sampling and laboratory testing program was undertaken to characterize the environmental impact of soluble salts from bottom ash. The obtained results reveal that the leaching concentrations of Cl⁻ and SO₄²⁻ exceed the limit specified in the class V standard of surface water, which are 2.06–2.17 times and 1.08–1.25 times, respectively. By examining the long-term environmental influence under the condition of continuous rainfall, the leaching of Cl⁻ mainly occurs in the early leaching stage, and the maximum leaching concentration reaches 19,700 mg/L. The release concentration of Cl⁻ begins to be lower than the class V standard of surface water when continuous rainfall approaches the total rainfall for 13 months. The cumulative release of Cl⁻ in the bottom ash is 2.8–5.4 mg/g. Both rainfall intensity and rain pH affect the release of Cl⁻. The obtained results derived from the constant head tests indicate that stagnant water caused by rainfall deteriorates the release of soluble salt into the groundwater in only 1 day, especially at the early stage of 12 h. This work provides some basic information about how to minimize damage to the surrounding environment caused by the leaching of salt in bottom ash.</p></div>","PeriodicalId":807,"journal":{"name":"Waste Disposal & Sustainable Energy","volume":"5 4","pages":"525 - 534"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132949929","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}
