This study evaluates its adoption as a potential adsorbent for methylene blue (MB) in aqueous solution. Cement mortar, roof tiles, and tiles were disintegrated and sieved for physicochemical characterization (pH, potential redox – Eh, electrical conductivity – CE, cationic exchange capacity—CEC, point of zero charge – PZC, specific surface area – SSA, pore distribution, functional groups, and elemental composition). The effect of initial concentration, pH, granulometric fraction and time were evaluated in adsorption and desorption studies. The results of adsorption studies were analyzed using nonlinear kinetic models and equilibrium data were analyzed by Langmuir, Freundlich, Sips, and Temkin isotherm models. The CDW evaluated has alkaline pH (pH 8.4 – 11.6) with high EC (680.5 – 1054.5 µS cm⁻¹), reductive environment (-223 – -66 mV), low CEC (0.45 – 1.40 cmol_c kg⁻¹), SSA (1.83 – 11.06 m² g⁻¹), and basic PZC (8.3 – 10.0). Initial concentration, pH and adsorbent particle size affected the removal efficiency and desorption rate. Roof tiles showed higher MB removal efficiency (84.5%), followed by cement mortar (61.1%) and tiles (41.6%), and the materials displayed the following maximum adsorption capacities (q_m): tiles (13.983 mg g⁻¹) &gt; roof tiles (8.389 mg g⁻¹) &gt; cement mortar (1.305 mg g⁻¹). Pseudo-first order model best described the chemical kinetics.

RuCl3 modified hollow Co3O4 nanospheres (Ru3+-Co3O4 HNSs) were utilized to establish a colorimetric sensor for selective determination of sulfide ions (S2-). The hollow Co3O4 nanospheres after doping of Ru3+ provide large surface area and more active sites, thereby boosting the electron transport and the affinity to the substrates. Specifically, the as-prepared Ru3+-Co3O4 HNSs exhibited remarkable peroxidase-like (POD-like) activity, which can catalyze colorless 3,3′,5,5′-tetramethylbenzidine (TMB) to blue oxTMB at neutral pH condition. Furthermore, the Ru3+-Co3O4-based colorimetric sensor achieved a wide linear range (0.5-20 μM) and a low detection limit (0.051 μM) for S2- ions concentration, as well as good selectivity, reproducibility and practicability in sewage water. This research aims to boost the accuracy of S2- detection and shed light on application prospects in the water environmental fields.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142138420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

With the ever-increasing global population and the increased need to meet the food demand, the ability to increase crop yield has become a pressing concern, especially considering that crop production has been threatened by increased biotic and abiotic stress. Previous studies have evaluated photosynthetic system structure and population photosynthesis based on agronomic and molecular biology. However, these methods require a long study period and a high cost. Therefore, identifying a fast, simple, and cheap strategy to improve plant photosynthesis is crucial for future crop production. Plant nanobiotechnology, as a new interdisciplinary field, provides remarkable insight into plant stress tolerance, chemical delivery, and transgenes. In this review, to provide new insights for future plant nanobiotechnological studies, we examine previous studies on photosynthesis and enhancing photosynthesis through plant nanobiotechnology and suggest possible strategies for increasing photosynthesis.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142138419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The decolorization rate reached up to 98% within 10 min when the mediator acetosyringone was present. Decolorization was attributed to the degradation of the dye by laccase, as analyzed using liquid chromatography-mass spectrometry (LC–MS). At least three dominant intermediates (m/z 167.993, 194.475, 118.040) were identified, deriving from the original dye (m/z 521.044). Compared to the non-decolorized dye solution, the decolorized dye ones at various concentrations exhibited lower toxicity towards aerobic activated sludge (AS). This was evident from the significantly higher respiratory intensity of AS, with an O₂ uptake of 35 mg for the decolorized solution versus 11 mg for the non-decolorized solution after 12 h at a 100 mg/L dye concentration.

In many urban areas that receive substantial snowfall, road salt application has been ascribed as the main source of chloride driving the FSS. In rural areas, however, inorganic (e.g. chemical) and organic (e.g. manure) fertilizer applications have been found to be the most important sources of chloride. Herein, we compared daily mean concentrations of chloride over the past decade of time between Coldwater Creek and Chickasaw Creek, two tributaries of Grand Lake St. Marys, the largest reservoir in Ohio. We also used Weighted Regressions on Time, Discharge, and Season (WRTDS) analyses to visualize trends in chloride data and compared chloride vs. nitrate levels to delineate likely sources of chloride for the two streams. We found that road salt application increased over time in both subwatersheds and that 37% and 25% of the chloride could be apportioned to road salt as a source in Coldwater Creek and Chickasaw Creek, respectively. Additionally, in Coldwater Creek, 37% of the chloride was apportioned to animal or septic sources, while 25% was apportioned to inorganic fertilizers, in comparison with 30% and 42% for Chickasaw Creek. Monitoring and assessing salinized streams for both chemical and biological water quality is important, particularly since the FSS has become increasingly linked to declines in water quality (e.g. harmful algal blooms, including recent upticks in <i>Prymnesium parvum</i> blooms) and is expected to be exacerbated with global climate change (e.g. increased precipitation causing increased runoff of chloride from the land).</p>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":2.52,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200355","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}

The result demonstrated that a large number of organic materials and inorganic salt leached to the surrounding environment by the decomposition of waste at open dumping site which significantly pollutes the groundwater sources of nearby areas.
