Characterizing the composition of mercury (Hg) isotopes in the atmospheric emissions of cement plants is critical to understand the global circulation of Hg because large quantities of Hg are released from this source annually. A pre-calciner cement plant in Guizhou Province in Southwest China was selected to investigate the mass dependent fractionation (MDF) and mass independent fractionation (MIF) of Hg in the entire production process and the speciated Hg isotope composition in stack gas. Significant MDF and insignificant MIF were observed in this cement plant. Different raw/correction materials have δ202Hg signals ranging from -1.68 to -2.19‰. Raw meal is featured with lighter Hg (δ202Hg = -2.83 ± 0.18‰) as results of Hg circulation and accumulation during the clinker production. Cement products possess negative δ202Hg values (-1.98 ± 0.02‰) due to the input of light δ202Hg isotopes through additives/retarder limestone, and fly ash and gypsum from coal-fired power plant (CFPPs). Speciated Hg isotopes in the stack gas of the kiln tail and kiln head show no significant differences, and δ202Hg and Δ199Hg in the discharged flue gas averaged at -2.03 ± 0. 31‰ and -0.03 ± 0.07‰, respectively, which has negative δ202Hg characteristics with other anthropogenic sources.This work describes a simple and environmental-friendly method for the simultaneous determination of five benzotriazole derivatives (BTRs) and four benzothiazole derivatives (BTs) that are frequently found in surface water. The target analytes were efficiently extracted from water samples using a "green" deep eutectic solvent (DES) as the extraction solvent based- ultrasound-assisted emulsification microextraction (DES-USAEME), and their determination were performed by ultrahigh-performance liquid chromatography and electrospray ionization (+)-quadrupole time-of-flight mass spectrometry (UHPLC-ESI(+)-QToF-MS). The DES was composed of a mixture of choline chloride and phenol (molar ratio 12). The DES-USAEME factors were optimized by a Box-Behnken Design coupled response surface methodology. The developed method was validated, providing limits of quantitation (LOQs; 02 μg L-1), high precisions (1-8%), and satisfactory mean spiked recoveries (72-104 %). Relatively high total concentrations of the target analytes were found in samples collected from a reservoir (47.2-101.3 μg L-1), which may have been released from tire-wear particles and scrap tires from buses and old tires that were strung alongside the shuttle boats to prevent the boats from coming into contact with each other or from impacting against the dock during docking. This is the first study on the occurrence of BTRs and BTs in reservoir samples.Pinewood biochar (PBC)-supported metallic silver (Ago) was prepared via a one-step carbothermal reduction route (AgH) or a wet-chemistry reduction method (AgW). XRD and SEM confirmed Ago was soldered on PBC matrix. Low methylene blue (MB) sorption was observed for unsupported Ago nanoparticles (AgNP), AgH and AgW. Under ultraviolet (UV) light irradiation, net MB degradation by AgH (15.88 g kg-1) was higher than that of AgW (12.50 g kg-1) and AgNP (10.27 g kg-1). TOC removal percentages after degradation corresponded largely to reduction of MB concentrations in solution, indicating MB was dominantly mineralized. Electron paramagnetic resonance (EPR) revealed that MB was degraded by reactive oxygen species (ROS) such as hydroxyl radical (OH), superoxide radical (O2-) and singlet oxygen (1O2). The scavenging experiments further suggested that OH scavengers suppressed MB degradation to a greater extent than other quenchers. Compared to AgW, AgH possessed greater abundance of persistent free radicals, which enhance ROS generation. PBC could also improve separation of electron-hole (e--h+) pairs and enhance electron transfer ascribing to favorable carbon structure. Besides, PBC-Ago maintained good antimicrobial efficacy over E.coli DH5α. This work presented a facile carbothermal route to prepare Ago-based photocatalysts for dye removal and microbial inhibition in industrial wastewater.Bisulfite-activated permanganate (PM/BS) process has proven to be a promising method for trace organic contaminants (TrOCs) abatement.  https://www.selleckchem.com/products/Novobiocin-sodium(Albamycin).html  However, to our knowledge, most previous studies on PM/BS process were limited in synthetic water at lab-scale. Hence, the performance of TrOCs abatement by PM/BS process was investigated in real waters in this study, and for the first time, its feasibility as a pretreatment process was evaluated at pilot-scale. The lab-scale results indicated that almost all tested TrOCs could be completely removed from pure water, while their removal efficiencies varied widely from ∼20 % to ∼90 % in real waters. Correlation analysis suggested that TrOCs abatement decreased linearly with increasing concentration of dissolved organic matter (DOM) and halide ions in real waters. The TrOCs with electron-donating groups were more likely to be decomposed in PM/BS process. The PM/BS pretreatment produced MnO2 and decreased the aromatic signal of the DOM, which enhanced the removal of DOM during subsequent coagulation-sedimentation processes. Comparing with ozonation, chlorination, and permanganate processes, PM/BS process showed some advantages in terms of TrOCs abatement and operating costs. Furthermore, the pilot-scale experiment confirmed that PM/BS process combined with traditional water treatment processes could achieve excellent TrOCs abatement (greater than 84%).Aluminum (Al) stress in acid soils is one of the major factors limiting crop productivity. ATP binding cassette (ABC) transporters have numerous roles in plants, but the link between ABCB protein subfamily and plant Al tolerance is still elusive. Here, we identified and characterized a novel tonoplast HvABCB25 in barley root cells. HvABCB25 was up-regulated in the transcriptome of Al-tolerant wild barley XZ16 under Al treatment and was highly Al-inducible in root tips. ABCB25 is originated from Streptophyte algae and evolutionarily conserved in land plants. Moreover, silencing HvABCB25 in Al-tolerant XZ16 led to significant suppression of Al tolerance as indicated by significantly reduced root growth and enhanced Al accumulation in root cells. Conversely, HvABCB25-overexpressed plants and Golden Promise showed similar Al content in whole roots and in cell sap, but the overexpression lines exhibited significantly higher Al-induced relative root growth and dry weight. Al florescence in cytosol of root cells were significantly less in overexpression lines than that in GP.
