An original multiresidue method based on thermal extraction (TE) and gas chromatography/tandem mass spectrometry (GC/MS/MS) was developed to simultaneously quantify, from a very small amount of sample (a few milligrams), a wide range of concerning SVOCs, including polycyclic musks, organochlorines (OCs), organophosphates (OPs), oxadiazolones, polycyclic aromatic hydrocarbons (PAHs), polybromodiphenylethers (PBDEs), polychlorobiphenyls (PCBs), phthalates and pyrethroids, in indoor settled dust. Method limits of quantification (LOQs) ranged from 5 ng g(-1) for PCBs, oxadiazon, 4,4′-DDE and 4,4′-DDT to 2000 ng g-1 for DEHP for a 2 mg sample of sieved dust. The proposed method was successfully validated in terms of accuracy and precision via replicate analysis of four different standard reference materials (SRMs 1649b (Urban Dust), 2585 (Organic Contaminants in House Dust), 2786 and 2787 (Fine Atmospheric Particulate Matter)) supplied by the National Institute of Standards and Technology (NIST) and was applied to five real indoor settled dust samples collected in French schools. In addition, its performance was compared to that of a previously published method based on pressurized liquid extraction (PLE) and GC/MS/MS. The different results obtained demonstrate the advantages of the proposed method over conventional methods and illustrate its two main features: i) its ease of use and very rapid implementation in only three steps (sieving, weighing and analysis), which make it particularly appropriate for environmental monitoring programs and large-scale studies, and ii) its ability to precisely and accurately quantify a wide range of SVOCs from trace (a few ng g(-1)) to highly concentrated (several mg g-1) compounds from only 2 mg of sieved dust.

The direct transformation of lignin into fuels and chemicals remains a huge challenge because of the recalcitrant and complicated structure of lignin. In this study, rhenium oxide-modified iridium supported on SiO2 (Ir-ReOx/SiO2) is employed for the one-pot conversion of various lignin model compounds and lignin feedstocks into naphthenes. Up to 100 % yield of cyclohexane from model compounds and 44.3 % yield of naphthenes from lignin feedstocks are achieved. 2 D HSQC NMR spectroscopy before and after the reaction confirms the activity of Ir-ReOx/SiO2 in the cleavage of the C-O bonds and hydrodeoxygenation of the depolymerized products. H-2 temperature-programmed reduction, temperature-programmed desorption of NH3, IR spectroscopy of pyridine adsorption, X-ray photoelectron spectroscopy, X-ray absorption fine structure analysis, and control experiments reveal that a synergistic effect between Ir and ReOx in Ir-ReOx/SiO2 plays a crucial role in the high performance; ReOx is mainly responsible for the cleavage of C-O bonds, whereas Ir is responsible for hydrodeoxygenation and saturation of the benzene rings. This methodology opens up an energy-efficient route for the direct conversion of lignin into valuable naphthenes.

The liquid organic hydrogen carriers (LOHCs) are promising materials for hydrogen storage. The standard molar enthalpies of formation, Delta H-f(m)o (liq/cr) of diphenyl ether substituted with methyl, methoxy, and hydroxyl substituents were measured by the high-precision combustion calorimetry. Enthalpies of vaporization/sublimation Delta(g)(l,cr) H-o(m) (298.15 K) of these compounds were obtained by the transpiration method. Enthalpies of fusion of 2- and 4-hydroxy-diphenyl ether were measured by differential scanning calorimeter. Gas-phase enthalpies of formation Delta H-f(o)m (g, 298.15 K) of substituted diphenyl ethers calculated by the G4 method were in an excellent agreement with the experimental results. Enthalpies of the hydrogenation/dehydrogenation reactions of diphenyl ether derivatives were estimated and compared with the data available for other potential LOHC. A set of thermodynamic properties of diphenyl ether derivatives of benchmark quality was recommended for thermochemical calculations. Equilibrium temperatures of hydrogenation/dehydrogenation processes were calculated and compared with those of benzene derivatives. Because of their high hydrogen storage capacity, as well as very low volatility, these compounds could be considered as seminal candidates for LOHC.

Schultz, IR; Kuo, LJ; Cullinan, V; Cade, S in [Schultz, Irvin R.; Kuo, Li-Jung; Cullinan, Valerie; Cade, Sara] Pacific Northwest Natl Lab, Marine Sci Lab, Sequim, WA USA published Occupational and dietary differences in hydroxylated and methoxylated PBDEs and metals in plasma from Puget Sound, Washington, USA region volunteers in 2020.0, Cited 54.0. Quality Control of Diphenyl oxide. The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8.

Electronic waste (E-waste) recycling is a rapidly growing occupation in the USA with the potential for elevated exposure to flame retardants and metals associated with electronic devices. We previously measured polybrominated diphenyl ethers (PBDEs) in plasma from E-waste workers and found them similar to non-E-waste workers. This study focused on structurally related PBDE derivatives, the hydroxylated (OH-PBDEs) and methoxylated (MeO-PBDEs) forms along with metals known to occur in E-waste. Humans can metabolize PBDEs and some MeO-PBDEs into OH-PBDEs, which is a concern due to greater health risks associated with OH-PBDEs. We measured 32 different OH-PBDEs and MeO-PBDEs in plasma samples provided by 113 volunteers living in the greater Puget Sound region of Washington State, USA. We measured 14 metals in a subset of 10 E-waste and 10 non-E-waste volunteers. Volunteers were selected based on occupational and dietary habits: work outdoors and consume above average amounts of seafood (outdoor), electronic waste recycling (E-waste) or non-specific indoor occupations (indoor). A two-week food consumption diary was obtained from each volunteer prior to blood sampling. OH-PBDEs were detected in all volunteers varying between 0.27 and 102 ng/g/g-lipid. The MeO-PBDEs were detected in most, but not all volunteers varying between n.d. 60.4 ng/g/g-lipid. E-waste recyclers had OH-PBDE and MeO-PBDE plasma levels that were similar to the indoor group. The outdoor group had significantly higher levels of MeO-PBDEs, but not OH-PBDEs. Comparison of plasma concentrations of BDE-47 with its known hydroxylated metabolites suggested OH-PBDE levels were likely determined by biotransformation and at least two subpopulations identified differing in their apparent rates of OH-PBDE formation. The metals analysis indicated no significant differences between E-waste workers and non-E-waste workers. Our results indicate E-waste workers do not have elevated plasma levels of these contaminants relative to non-E-waste workers. (C) 2020 Elsevier B.V. All rights reserved.

This study illustrated the pyrolysis of banana peel (BP) as a potential waste management solution. Samples were characterized through Fourier transform infrared spectrometry (FTIR), elemental analysis, and high heating value (HHV) calculation. After pyrolysis experiments were performed at different heating rates (10, 20, 30, and 40 degrees C min(-1)) by using a thermogravimetric analyzer coupled with FTIR (TG-FTIR), the apparent activation energies were computed with Friedman, Kissinger-Akahira-Sunose (KAS), and Flynn-Wall-Ozawa (FWO) methods, and the evolved gaseous products were analyzed simultaneously. During pyrolysis, BP underwent three devolatilization steps accompanied by the evolution of some major gaseous products, including CO2, CH4, H2O, CH3COOH, C=C, C6H5OH, HCOOH, and CH3CH2OH. Among them, C=C, CH3COOH, and CO2 accounted for approximately 71.56% of the total gaseous products. Gas evolution was more significantly influenced by the pyrolysis temperature than by the heating rate. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) analysis confirmed the presence of some high-energy compounds and valuable chemicals containing aromatic, aldehyde, ketone, and other functional groups. In terms of preliminary energy balance, more than 70% of the total energy output was attributed to the liquid pyrolytic products followed by the solid and gaseous products. The energy recovery ratio of BP pyrolysis was superior to that of other fuel feedstocks. This work provided insights into resolving environmental problems associated with BP management by pyrolyzing BP as a potential source of renewable bioenergy.

Efficient oil adsorption and recovery is a generous universal importance for future energy demand and environmental protection. Adsorbents based on 2D flatland with engineered surfaces can overcome the limitations of conventional methods for selective oil adsorption. Here, we report magnetic hydrophobic/oleophilic graphitic C3N4 nanosheets that exhibit excellent oil sorption performance and rapid removal of adsorbed oil using an external magnet. Combining porous and nanosheets structure along with magnetic FeNi3 and fatty acid surface functionalization make the system an efficient adsorbent for adsorbing and separating crude oil from water. The graphitic sheets selectively adsorb crude oil with enhancement of thickness up to 9 folds and mass by 4.5 times than the pristine nanocomposite system. The smart adsorption property of g-C3N4@FeNi3 has been realized through comprehensive adsorption kinetics and inclusive isotherm studies. The nanocomposite can be further recycled and reused in an eco-friendly manner for oil adsorption and recovery.

A novel interzeolite transformation strategy using internally confined organic structure directing agents (OSDAs), called the OSDA-confined strategy, is proposed for highly crystalline nanosized high-silica ZSM-5 zeolite synthesis, by which high yield and fast synthesis of ZSM-5 is achieved using BEA zeolite as a raw material. The transformation process was investigated by XRD, SEM, ICP, FTIR and UV Raman spectroscopy, which revealed that the decomposition of a parent zeolite and the crystallization process of products were well modulated by the confined OSDA. The transformation process could be divided into three stages consisting of raw material deconstruction, small size product formation and product growth. The strong etching power of NaOH contributes to the fast decomposition of BEA zeolites. In addition, tetrapropylammonium hydroxide (TPAOH) as an OSDA was confined in the parent zeolite instead of being added into the mother liquid, achieving a high local concentration of TPAOH, which could reduce the decomposition rate of the parent BEA zeolite and promote the efficient organization of the building units generated by the decomposition of the BEA zeolite. Thereof, a high yield was achieved by the synergistic effect of NaOH and occluded TPAOH. During the interzeolite transformation process, the six-membered rings (6Rs), five-membered rings (5Rs) and four-membered rings (4Rs) in the BEA zeolite framework were disassembled and combined with the help of 5Rs to produce the ZSM-5 zeolite structure. Moreover, due to the nanoscale and large surface area, the obtained ZSM-5 zeolite catalyst showed extremely high catalytic activity in the self-etherification reaction of benzyl alcohol (BA) to dibenzyl ether (DE). This study provides insights into the interzeolite transformation process, which would be helpful for achieving size control and high-efficiency synthesis.

The use of copper for reducing nosocomial infections or healthcare-acquired infections (HAI) has been carried out in intensive care units (ICU) by replacing some objects generally made of stainless steel or other materials with solid pieces of copper. The authors’ proposal for a sustainable use of copper consists of introducing it in a lamina + adhesive format. This proposal has been tested in an ICU at the Ceuta Hospital in Spain. It has been found to provide an equally efficient solution as antibacterial material than the usual solid format, but with only a layer of 50 microns of copper, which is a high-cost and limited resource. After that intervention, some improvements are also proposed: a standardization of the pieces chosen to cover with a lamina of copper for saving material; and another method of replacement aiming to lower the time that the ICU cannot be used. To ensure that the proposed bonding method is harmless to human health and the adhesive does not interfere with the indoor environment by releasing toxic chemicals, the lamina + adhesive sheet has been further tested. The results and proposals are briefly shown.

Addition of DMSO is found to greatly accelerate the aqueous hydrolysis of organohalides to alcohols, providing a neutral, more efficient, milder and more economic process. Mechanistic studies using O-18-DMSO and O-18-H2O showed that, contrary to the opinion that DMSO works as a dipolar solvent to enhance water’s nucleophilicity, the accelerating effect comes from a complete oxygen transfer from DMSO to organohalides through generation of ROS+Me2.X- salts through C-O bond formation, followed by O-S bond disassociative hydrolysis of ROS+Me2.X- with water. This method is applicable to a wide range of organohalides and thus may have potential for practical industrial application, owing to easy recovery of DMSO from the H2O/DMSO mixture by regular vacuum rectification.

Although the extensive use of synthetic insecticides to control mosquito vectors have gained significant success, meanwhile resulted in various problems, such as increase in insecticide-resistant mosquitoes, environmental pollution, and health threat to human beings. Hence, there is an urgent need for alternative insecticides and effective synergists to combine with existing insecticides, which are safe to public health and environment. In this work, the larvicidal activity of 53 commercial essential oils (EOs) and their synergistic effect with deltamethrin against Aedes albopictus adults were screened, then the main constituents of active EOs were analyzed by GC-MS. The most potent EOs against the larvae are from Foeniculum vulgare (fennel), Thymus vulgaris (thyme), Citrus medica (lime), and Camellia sinensis (green tea) with LC50 values of 27.5, 31.6, 51.3, 53.5 ppm, respectively. The most efficient EOs enhancing the efficacy of deltamethrin are C. sinensis (green tea), the co-toxic factor is 316.67, which is more than the positive control PBO (co-toxic factor = 283.35). It suggests that there is significant potential of natural EOs in the application of mosquito control as larvicides or synergists for enhancing efficacy of current adulticides.
