The developed method was used successfully to measure geosmin and 2-MIB emission from just above disturbed and undisturbed soils, indicating that this method detects both compounds readily from atmospheric samples. Both geosmin and 2-MIB were present as background concentrations in the open air, while disturbed soils emitted much higher concentrations of both compounds. Surprisingly, 2-MIB was always detected at higher concentrations than geosmin, indicating that a focus on its detection may be more useful for soil emission monitoring and more sensitive to low levels of soil disturbance.An emerging experimental framework suggests that endocrine-disrupting compounds are candidate obesogens. However, this potential effect has not yet been determined for Tricresyl phosphate (TCP), a mass-produced organophosphate flame retardant (OPFR) that has been exposed to human beings in many ways. Many OPFRs, including TCP, have been shown to activate pregnane X receptor (PXR), a nuclear receptor that regulates lipid metabolism. Accordingly, we found that TCP exposure caused lipid accumulation in HepG2 cells in this study. Therefore, to elucidate the role of PXR played in TCP metabolism and promotion of lipid accumulation, HepG2 cells were exposed to different concentrations (5 × 10-8 to 5 × 10-5 M) of TCP for 24 h. The enlarged hepatic lipid droplets and increased hepatic triglyceride contents were observed in HepG2 cells after TCP exposure for 24 h. This is the result of a confluence of lipogenesis increase and β-oxidation suppression imposed by PXR activation which was verified by the up regulation of genes in fatty acid (FA) synthesis and the down regulation of genes in β-oxidation. Surface plasmon resonance (SPR) analysis and molecular docking revealed favorable binding mode of TCP to PXR and the knockout of PXR gene with CRISPR/cpf1 system in HepG2 cells abolished TCP-induced triglyceride accumulation, thus underlying the crucial role of PXR in hepatic lipid metabolism resulting from OPFRs exposure. This study enhances our understanding of molecular mechanisms and associations of PXR in lipid metabolism disturbance induced by TCP and provides novel evidence regarding the lipotoxicity effect and potential metabolism pathway of OPFRs.The work presented here provides a complex environmental impact of sediments in vicinity to the area of the former Lazy coal mine site in the Upper Silesian Coal Basin (Czech Republic). The main aim of this work has been to determine the degree of contamination, to describe the organic matter, and to carry out sorption isotherms to see the size and distribution of pores in the monitored sediments that are the crucial parameters to assumption of removal mechanisms of elements carried in mine water. The results show that the greatest enrichment of Mn, Sr, Ba, and was in sediments of the first tens of meters from the mine water discharge sediments. Ba and Sr were precipitated as mineral barite and thus formed a dominant insoluble component in the river sediments, which were further carried by water flow towards the water reservoirs. Predominant amounts of fossil material and smaller quantities of carbonized and recent organic matter were altered by weathering and erosion processes. The coal materials have a relatively beneficial sorption capacity, which increases with the carbon content. The overburden waste should be considered for use in removing heavy metals in-situ.Cenospheres (CS) are spherical shaped inorganic frameworks present in with fly ash which is generated from coal-fired thermal power plants. These spherical structures were functionalized with imidazole and amine moieties to capture CO2 selectively from flue gases at elevated temperature. The functionalized CS have shown a high selectivity for CO2 adsorption (4.68 mmol g-1) over N2 (0.46 mmol g-1) at 333 K/1 bar from a simulated flue gas (0.15 CO2 and 0.85 N2, v%) composition of thermal power plants. When the moisture content reached to 30 vol% the adsorption capacity of CS materials was reduced to 20 vol% as compared to dry flue gas. The functionalized CS can be used repeatedly for 50 cycles without losing its adsorption capacity. The cost estimate for CO2 capture by using the proposed adsorption system would be $12.01/ton of CO2 which is lower as compared to amine absorption system and zeolite-based adsorption system reported in the literature. The CS materials are prepared from solid wastes reduce the cost of production and their large scale manufacturing is technically feasible to capture CO2 from industrial flue gases efficiently in near future.Low-temperature selective catalytic reduction of NOx by NH3 (NH3-SCR) for diminishing SO2 poisoning remains an issue in flue gas denitrification (DeNOx). Herein, A novel CNTs functionalized low temperature NH3-SCR catalyst CeO2/CNTs-GAC was prepared, which showed high NO conversion activity (100% at 150 °C) and SO2 resistance. The addition of CNTs restrained SO2 adsorption but improved the selective adsorption of NO, which restricted the deposition of (NH4)2SO4 and/or Ce2(SO4)3, and resulted in high SO2 resistance. this website The addition of CNTs facilitated the diffusion and transportation of NH3 and NO, and the electron transfer on CeO2/CNTs-GAC, leading to higher content of Ce3+ and adsorbed O species on the CeO2/CNTs-GAC surface and promoted formation of surface-adsorbed oxygen OA. Therefore, CeO2/CNTs-GAC provided abundant NO adsorption and activation sites, facilitating "fast SCR" reaction and enhancing the NH3-SCR reaction. The proposed CeO2/CNTs-GAC catalyst exhibited higher NH3-SCR activity, N2 selectivity, catalytic durability and SO2 resistance than CeO2/GAC.This research study investigated the synthesis of environmentally benign green emulsion liquid membrane (GELM) employing waste cooking oil (WCO) as diluent. The emulsion was prepared using D2EHPA as the carrier, Span 80 as surfactant, and sulphuric acid as internal/stripping agent. The influence of nine operating variables namely, Span 80 concentration, D2EHPA concentration, shaking time, shaking speed, pH of the feed, treat ratio (TR), H2SO4 concentration, lead concentration in feed, and volume ratio of organic phase to aqueous phase (O/A) on the performance of lead extraction was studied. Plackett Burman design (PBD), was employed for the screening of variables. The Pareto analysis shows that six variables were the most significant variables at the confidence level of 95%. The selected variables were then screened applying Box-Behnken design (BBD). The optimum values of the variables were D2EHPA concentration - 4.6 (v/v%), Span 80 concentration - 2.14 (v/v%), pH of the feed - 4.4, internal phase (H2SO4) concentration - 2 M, initial lead concentration - 173 ppm, phase ratio (O/A) - 1.
