Aerosol direct effects (ADEs) can modulate shortwave radiation as well as atmospheric dynamics and air quality. As the key absorbing component of aerosol, the black carbon (BC) largely determines the aerosol optical properties. Therefore, it is expected that BC emission controls might gain co-benefits from the simultaneous reduction of ADEs. To demonstrate such synergy, we quantified the ADEs changes and role of BC controls in China during 2013-2017 using a regional two-way coupled meteorology chemistry transport model. Results suggest that the control action effectively reduced wintertime PM2.5 concentration (-26.0 μg m-3) and associated ADEs. The influence of ADEs on surface shortwave radiation, 2-meter temperature, and planetary boundary layer height was weakened from -16.7 W m-2, -0.20°C, and -15.4 m in 2013 to -11.3 W m-2, -0.06°C, and -10.7 m in 2017, respectively. The enhancement of SO2, NO2, and PM2.5 concentrations due to ADEs was reduced from +3.1%, +5.2%, and +5.4% in 2013, to +2.6%, +4.5%, and +3.3% in 2017, respectively, demonstrating the extra benefit of air pollution controls by reducing ADEs. The BC emission reduced by 12.5% simultaneously along with the effective controls during 2013-2017. Such BC controls contributes 15.6-60.2% of such changes in the ADEs influence on meteorological variables, and 32.6-41.1% on air pollutants. More specially, the effectiveness of collaborative reduction of BC further reduced surface shortwave radiation in China by 3.6 W m-2 in January and 1.0 W m-2 in July, leading to a more weakened ADEs that bring extra benefits in reducing PM2.5 concentrations by 1.8 μg m-3 in January and 0.3 μg m-3 in July. Apparently, BC played a dominant role in modulating the ADEs and associated influences on meteorology and air quality, suggesting a wise control strategy by targeting absorbing component of PM2.5 reduction to address both air pollution and climate change in the future. © 2022, The Authors.

The blast furnace casthouse is a typical heavy-polluting factory building of a steel enterprise. During the tapping process and the taphole opening, the dust concentration in the factory building's workroom can reach tens of thousands mg/m3. Over time, the air pollutants in the workplace can have unwanted consequences on employees' health. This paper selected a typical blast furnace tapping workshop and measured on-site the characteristics of the wind speed distribution, temperature distribution, and soot concentration distribution during the taping period. A numerical simulation model was established to analyze the taphole smoke exhaust system's performance based on computational fluid dynamics. The findings are: the velocity, temperature, and smoke density distributions in the workplace were very uneven, and the thermal comfort of the workers' area was relatively poor. Also, the concentration of PM2.5 was mostly below 80μg/m3. Besides, due to the plant's on-site measurement, real data was obtained for numerical simulation verification, making the evaluation of the entire plant's ventilation performance more reliable. Hence, this article's finding provides a scientific basis for optimizing the air distribution in the blast furnace cast house's workplace. © 2021, CC BY.

The anthranilic diamide insecticide chlorantraniliprole has been extensively applied to control Lepidoptera pests. However, its overuse leads to the development of resistance and accumulation of residue in the environment. Four P450s (CYP6CV5, CYP9A68, CYP321F3, and CYP324A12) were first found to be constitutively overexpressed in an SSB CAP-resistant strain. It is imperative to further elucidate the molecular mechanisms underlying P450s-mediated resistance to CAP for mitigating its environmental contamination. Here, we heterologously expressed these four P450s in insect cells and evaluated their abilities to metabolize CAP. Western blotting and reduced CO difference spectrum tests showed that these four P450 proteins had been successfully expressed in Sf9 cells, which are indicative of active functional enzymes. The recombinant proteins CYP6CV5, CYP9A68, CYP321F3, and CYP324A12 exhibited a preference for metabolizing the fluorescent P450 model probe substrates EC, BFC, EFC, and EC with enzyme activities of 0.54, 0.67, 0.57, and 0.46 pmol/min/pmol P450 respectively. In vitro metabolism revealed distinct metabolic rates (0.97, 0.86, 0.75, and 0.55 pmol/min/pmol P450) and efficiencies (0.45, 0.37, 0.30, and 0.17) of CAP by the four recombinant P450 enzymes, thereby elucidating different catalytic activities of their proteins. Furthermore, molecular model docking confirmed metabolism differences and efficiencies of these P450s and unveiled the hydroxylation reaction in generating N-demethylation and methylphenyl hydroxylation during CAP metabolism. Our findings not only first provide new insights into the mechanisms of P450s-mediated metabolic resistance to CAP at the protein level in SSB but also demonstrate significant differences in the capacity of multiple P450s for insecticide degradation and facilitate the evaluation and mitigation of toxic risks associated with CAP application in the environment. © 2023, The Authors.

Vertical mixing within the planetary boundary layer (PBL) is crucial for determining surface-level pollutant concentrations. However, standard PBL schemes in chemical transport models (CTMs) often fail to adequately define the upper bounds of vertical mixing, particularly at night. This limitation frequently results in overestimated nocturnal concentrations of pollutants near the surface. To address this issue, we propose a parameterization of mixed layer height (MLH) derived from the Yonsei University (YSU) PBL scheme and thoroughly evaluate it by comparing simulations with various observations. We utilized the Weather Research and Forecasting model coupled with GEOS-Chem (WRF-GC) to simulate gas and aerosol distributions over South Korea during the Satellite Integrated Joint monitoring of Air quality (SIJAQ) campaign in 2021. The WRF-GC simulations incorporating the MLH parameterization improved the excessive titration of O3 and the overproduction of HNO3 and NO3− in the model. Consequently, the model performances in gaseous and aerosol simulations showed a better agreement with observations, with changes in normalized mean biases (NMBs) of NOX (from 50 % to −27 %), O3 (from −49 % to −28 %), NO3− (from 126 % to 91 %), NH4+ (from 113 % to 85 %), BC (from 322 % to 135 %), and PM2.5 (from 58 % to 28 %). © 2024 The Authors

Conducting a comprehensive metagenomic survey is pivotal for formulating effective public health protection strategies concerning drinking water reservoirs. Utilizing a curated database, a deep metagenomic sequencing (2.2 Tbps) was employed to analyze the antibiotic resistance genes (ARGs) panorama from 16 drinking water reservoirs. The discrepancy of ARG diversity in water and sediments emphasizes the pressing requirement for comprehensive and ongoing sediment monitoring. Employing metagenomic binning, Acinetobacter, Pseudomonas, and Mycobacterium were identified as high-risk genera harboring ARGs, alongside seven specific ARGs displaying a pronounced affinity for dispersion in aquatic ecosystems. The extensive data analysis brought to light an ongoing safety predicament in drinking water, particularly in regions reliant on river sources. Human activities have notably contributed to the propagation of ARGs, thereby fueling a pervasive contamination marked by the prevalence of extensively multidrug-resistant bacteria within the Enterobacteriaceae. Ultimately, a total of 15,117 metagenomic genomes were assembled, thus providing a valuable repository for subsequent research initiatives. The outcomes of this research suggest that establishing drinking water reservoirs within the tributaries of densely populated regions, under stringent protective measures, represents a promising and feasible strategy for mitigating the impact of bacterial antibiotic resistance on the environment. © 2023, The Authors.

Metal components in fine particulate matter (PM 2.5 ) are closely associated with many adverse health outcomes. Dynamic changes of metals in PM 2.5 are critical for risk assessment due to their temporal variations. Herein, an online method for real-time determination of multi-elements (As, Cd, Cs, Cu, Fe, Mg, Mn, Pb, Rb, Sn, Tl, and V) in PM 2.5 was established by directly introducing air samples into inductively coupled plasma mass spectrometry (ICPMS). Meanwhile, a quantified method using metal standard aerosols (Cr, Mo, and W) and high time-resolution for 3.3 min online measurement was developed and validated. The limits of detection were in range of 0.001–6.30 ng/m 3 for different metals. Subsequently, the real-time contents of multi-elements in PM 2.5 for 12 h over 33 days were measured at different air qualities. Temporal variations of crustal elements like Fe, Mg are similar as PM 2.5 , whereas toxic elements (Pb, As and Cd) have upward trends at dusk. This denoted the association with various emission sources and different exposure concentrations of metals. In addition to the acquisition of real-time information, online analysis of multi-elements in PM 2.5 is beneficial for atmospheric monitoring and provides critical insights for the different exposure risks of metals in PM 2.5 at varying times. © 2022, The Authors.

Enhanced Cr(VI) removal by nanoscale zerovalent iron through biogenic sulfidation:Comparison against corresponding chemical sulfidation

Cleaner Chemical Engineering 2025年 11卷

This study examines the effects of biogenic sulfidation and chemical sulfidation on the reactivity of nanoscale zerovalent iron (nZVI) for the removal of carcinogenic hexavalent chromium (Cr(VI)). Biogenic sulfidated nanoscale zerovalent iron (BS-nZVI) was synthesised by culturing nZVI with sulphate-reducing bacteria (SRB), while chemically synthesised sulfidated nanoscale zerovalent iron (CS-nZVI) was produced using a Na 2 S solution. Characterisation results indicated that both BS-nZVI and CS-nZVI were coated with FeS x , with BS-nZVI additionally covered by extracellular polymeric substances (EPS) secreted by the SRB. Both BS-nZVI and CS-nZVI exhibited significantly higher Cr(VI) removal efficiencies compared to nZVI, with values of 18.91 mg/g and 18.80 mg/g, respectively, versus 0.095 mg/g for nZVI. These improvements are attributed to the enhanced electron transfer properties of FeS x . In cyclic “sulfidation-Cr(VI) removal” experiments, biogenic sulfidation was found to be more effective than chemical sulfidation in enhancing and reactivating the Cr(VI) removal capacity of nZVI. The EPS associated with S-nZVI provided additional binding sites for co-precipitation of Cr(III)-Fe(III) during Cr(VI) removal, resulting in the formation of a loosely structured Cr(III)-Fe(III)-EPS co-precipitate. This co-precipitate mitigated the hindering caused by dense Cr(III)-Fe(III) passivation layers on electron transfer during Cr(VI) removal and cyclic sulfidation, in contrast to CS-nZVI. This study elucidates the synergistic effects of the coupled SRB-ZVI system for Cr(VI) remediation.

Brown carbon (BrC) holds scientific significance by influencing radiative balance, cloud condensation dynamics, and regional air quality. This study demonstrated that heavy-duty diesel vehicles (HDDVs) emit substantially higher levels of light-absorbing carbonaceous aerosols under aggressive conditions, such as frequent acceleration and high-speed phases, by investigating the emission profiles, formula distribution, and chromophore characteristics under various driving conditions. A non-targeted analysis of BrC was performed using Fourier-transform ion cyclotron resonance mass spectrometry coupled with a soft electrospray ionization source. The light absorption properties were assessed and revealed significantly higher light absorption during frequent acceleration and high-speed phases compared to low-speed phases. Formula distribution analysis highlighted a substantial presence of nitrogen-containing species, constituting 53–65% of the identified peaks, with high O/N ratios (≥ 3), double bond equivalent values (DBE > 10), and aromaticity equivalent (X_c≥ 2.5), which indicated the substantial contribution of aromatic structures, condensed aromatics, and nitrooxy functionalities to BrC chromophores.

Coagulation is not effective in treatment of emerging organic contaminants (EOCs) contaminated water and wastewater, and many researches focus on the hybrid technologies. In this study, a multifunctional inorganic oxidizing coagulant (IOC) was developed by a simple alkaline co-polymerization method to increase the efficiency and feasibility of coagulation in elimination of low molecular weight (MW) organic compounds, which were demonstrated by eight kinds of representative EOCs. The IOC present exceptional removal capabilities for hydrophilic with low logKow and nucleophilic (high NI) EOCs, like sulfamethazine (SMZ), tetracycline (TC), and ciprofloxacin (CIP), achieving removal efficiencies of 45-95%. The dynamic coagulation investigation conducted through continuous monitor on floc formation and growth demonstrated that large floc played minor role in EOCs removal. Instead, an obvious positive correlation between removal efficiency (REOCs) and floc growth rate (Sfloc), which was associated with the reactivity of EOCs with coagulant, was observed. Combined with the electron paramagnetic resonance (EPR) and ultra-high-performance liquid chromatography high-resolution mass spectrometry (UHPLC-HRMS) results, an innovative coagulation mechanism for EOCs abatement by IOC, namely oxidation-induced coagulation was proposed. Oxidizing agent in IOC promoted the formation of activate intermediates through nonradical pathway, which were more prone to complexation with aluminum than their original condition. Comparatively, traditional charge neutralization, adsorption and sweeping mechanisms involved in the aluminum sulfate (AS) and poly-aluminum chloride (PACl) coagulation systems, which generally lead to large but invalid flocs, turned out to inapplicable to EOCs removals. This study provides a novel strategy and inorganic coagulant for EOCs-contained water and wastewater treatments based on the oxidation-induced complexation mechanism, which was demonstrated to be a promisin
