Cement raw meal with MSS and different heavy metals was blended to examine the fixation ratios, chemical species, and cement crystalline phases in clinkers. The results showed that blending MSS could decrease the fixation ratio of Cr, Ni, Cu, and Zn in the produced clinker by 5% to 25%. And Cr, Cu, and Zn were mainly incorporated into clinkers as metal silicates, Ni was mainly solubilized in Mg O to form magnesium nickel oxides, and the transition phases were mainly metal aluminum oxides as indicated by X-ray diffraction. The reduction of fixation ratios was likely attributed to the presence of impure elements, such as sodium and phosphorus in MSS. In addition, high concentrations（eg, 1.7 wt%） of chlorine in MSS led to metal chloride formation that could vaporize Cu, Cr, Ni, and Zn. To summarize, introducing MSS would decrease the fixation ratios of heavy metals due to the presence of impure elements, such as sodium and phosphorus and chlorine.

In order to explore the influence of satellite observation data on the top-down NOx estimates at regional scale, the top-down NOx emissions for Yangtze River Delta (YRD) region at 9 km spatial resolution were developed with Peking University Ozone Monitoring Instrument NO2 product (POMINO) v1 and POMINO v2 satellite observation data in January and July of 2016. The differences of top-down NOx estimates derived from the two satellites were quantitative evaluated, and the reasons were comprehensively analyzed. The total NOx emissions based on POMINO v2 in January and July was 27% and 45% higher than those derived with POMINO v1, respectively. It indicated that the difference of top-down estimate derived from different satellite observation in summer was larger than that in winter. Considering that the difference between the two observations in January was similar to that in July, it was mainly because that the sensitivity of NO2 concentration to emissions was larger in summer than in winter. Top-down estimates derived from the two satellite observation were evaluated with air quality model (AQM) and ground observation. The model performances derived from top-down NOx emission based on POMINO v1 were better than those based on POMINO v2. The probable reason was that the NO2 vertical column densities (VCD) in POMINO v1 was closer to available ground-based MAX-DOAS observations during cloudless days and the satellite observation of cloudless was usually selected to inversing NOx emission. © 2020 Authors.

Disaccharides are composed of two monosaccharide subunits joined by a glycosidic linkage in an α or β configuration. Different combinations of isomeric monosaccharide subunits and different glycosidic linkages result in different isomeric disaccharide products. Thus, direct discrimination of these disaccharide isomers from a mixture is extremely difficult. In this paper, a hetero-octameric Mycobacterium smegmatis porin A (MspA) nanopore conjugated with a phenylboronic acid (PBA) adapter was applied for disaccharide sensing, with which three most widely known disaccharides in nature, including sucrose, lactose and maltose, were clearly discriminated. Besides, all six isomeric α-D-glucopyranosyl-D-fructoses, differing only in their glycosidic linkages, were also well resolved. Assisted by a custom machine learning algorithm, a 0.99 discrimination accuracy is achieved. Nanopore discrimination of disaccharide isomers with different glycosidic linkages, which has never been previously demonstrated, is inspiring for nanopore saccharide sequencing. This sensing capacity was also applied in direct identification of isomaltulose additives in a commercial sucrose-free yogurt, from which isomaltulose, lactose and L-lactic acid were simultaneously detected.

Zunyi City, in the Yangtze River Economic Belt, faces significant pollution challenges in the Wujiang and Chishui watersheds. This study analyzed water quality changes from 2021 to 2023. To support current and future water environment management, pollutant emissions in 2022 were estimated, and major pollutants were traced during flood and non-flood seasons. Emission thresholds were established for districts and counties firstly, identifying key areas for pollution control. This research innovatively integrates urban non-point sources and forest soil erosion into emissions calculations and introduces pollution emissions threshold. Results indicate that agricultural non-point sources, particularly livestock farming and crop cultivation, are the dominant contributors to watershed pollution, while urban non-point sources play a comparatively minor role, for both two studied watersheds. Natural factors including drought and forest soil erosion also significantly influence pollution degree, particularly during flood seasons when increased erosion intensifies pollutant transport, which was especially pronounced for Chishui watershed. Methodologically, the Positive Matrix Factorization (PMF) model demonstrated greater accuracy and reliability than the Absolute Principal Component Scores-Multiple Linear Regression (APCS-MLR) model in apportioning complex pollution sources, for both two studied watersheds. Based on pollution emissions and source apportionment, regional emission thresholds for COD, NH3-N, TN, and TP were proposed. The results reveal that COD emissions in Xishui, Huichuan, Bozhou, and Chishui exceeded their respective thresholds, with TN and TP also surpassing limits in some areas. In summary, this study provides a scientific basis for targeted water quality management in Zunyi City and validates the PMF model as a reliable tool for source apportionment in complex watershed environments. © 2025 Elsevier Ltd

Despite being low in concentration, the presence of broad-spectrum chemical constituents in drinking water is a fact of modern life. The current drinking water chemical risk assessment practice predominantly relies on drinking exposure and chemical toxicity data, providing a valuable tool for regulation. However, only a fraction of chemicals is retained for a considerable duration within the human body, as the remainder are excreted or metabolized. This limits the efficacy of risk assessment when exclusively relying on water contaminants ingestion dose and toxicity potencies. We propose large scale incorporation of a bioavailability factor, F , into the calculation of chemical-mediated human health risk assessment for drinking water. Specifically, F values account for the ratio of one compound in human circulation and excretion and are multivariable specific, such as exposure route specific, and gender specific. Utilizing disinfection by-products (DBPs), an important group of chemicals commonly found in drinking water as an example, we provided detailed explanations of F values. Through incorporation of the F values, the accuracy of drinking water human health risk assessment may be improved as the biological retention ratio is accommodated, providing leniency on chemicals that less interact with the human body during internal retention. This approach has clear implications for the subsequent control measures and national drinking water standards updates for emerging pollutants.

When a chemical or biological agent is suddenly released into a ventilation system, its dispersion needs to be promptly and accurately detected. In this work, an optimization method for sensors layout in air ductwork was presented. Three optimal objectives were defined, i.e. the minimum detection time, minimum contaminant exposure, and minimum probability of undetected polution events. Genetic algorithm (GA) method was used to obtain the non-dominated solutions of multi- objectives optimization problem and the global optimal solution was selected among al of the non-dominated solutions by ordering solutions method. Since the biochemical attack occurred in a ventilation system was a random process, two releasing scenarios were proposed, i.e. the uniform and the air volume-based probability distribution. It was found that such a probability distribution affected the results of optimal sensors layout and also resulted in different detect time and different probability of undetected events. It was discussed how the objective functions are being compatible and competitive with each other, and how sensor quantity affect the optimal results and computational load. The impact of changes on other parameters was given, i.e. the deposition coefficient, the air volume distribution and the manual releasing. This work presents an angle of air ductwork design for indoor environment protection and expects to help in realizing the optimized sensor system design for sudden contaminant releasing within ventilation systems.

Nanofiltration (NF) can help address the growing need for sustainable water treatment and wastewater resource recovery, yet its ion-selectivity mechanisms remain poorly understood under varying pH and pressure. Here, we integrate experimental data, DSPM-DE modeling, and ab initio molecular dynamics (AIMD) to investigate Na + /Mg 2+ and Cl − /SO 4 2− separation by three NF membranes: commercial NF270, NF90, and a custom piperazine-based (PIP) membrane. We find that extreme acidic or alkaline feed conditions expand the PIP membrane pore radius by up to 60 % while raising volumetric charge density by 4–5 times, enabling divalent-ion retention to improve even at higher flux. When multiple ions coexist, cation or anion selectivity values hinge on these pH- and pressure-driven changes in pore structure and charge. By capturing dynamic ionization within the membrane, we gain a deeper and more accurate perspective on how molecular-level properties evolve under high salinity, multi-ion competition, and extreme pH, those scenarios are common during sustainable water and wastewater treatment. The results indicate that controlled pH or pressure modulation can be harnessed to enhance divalent-ion retention, optimize NF performance, and reduce overall energy demands. By linking macroscopic modeling with molecular-scale insights, this study provides a mechanistic blueprint for refining NF design and operation, offering a pathway to next-generation high-selectivity membranes for water treatment, wastewater reclamation, and resource recovery.

Nutrient loading is the key cause of lake eutrophication, and exploring management options to reduce river export of nutrients to lake is crucial. By applying the MARINA-Lakes (Model to Assess River Inputs of Nutrients to lAkes) model to project river export of nitrogen (N) and phosphorus (P) to Lake Taihu by sources at the subbasin scale, we find that rivers are projected to export less total dissolved nitrogen (TDN), but more total dissolved phosphorus (TDP) to Lake Taihu in 2050. The critical nutrient loads (CNLs) may decrease by 25–53% by 2050 due to warmer climates, widening the gap between CNLs and actual nutrient loads. Improved nutrient management in agriculture and sewage systems is expected to reduce river export of TDN by 5–12% and TDP by 19–39% in 2050. However, this may not be sufficient to reduce future nutrient pollution below CNLs. Nature-based solutions, such as constructed wetlands, can keep future TDP below CNL in 2050, but reducing TDN pollution below CNLs will remain challenging. This study can contribute to formulating effective solutions to reduce nutrients and restore Lake Taihu's clarity.

Pharmaceuticals have gained global attention in recent decades due to their substantially growing demand and ecological impacts. This study aimed to comprehensively investigate the pollution status of 64 target pharmaceuticals in water (i.e., dissolved phase), suspended particulate matter, and sediment in the Yangtze River Basin (YRB). Across the three environmental compartments, our results uncovered the presence of 49−58 and 23−62 pharmaceuticals in YRB and Huangpu River (HR), respectively. The downstream area of HR showed significantly higher cumulative concentrations of detected pharmaceuticals compared to the other studied sections in the YRB ( p  < 0.05), reaching 4995.61 ± 4288.16 ng/L in the dissolved phase. The suspended particulate matter demonstrates a higher capacity to adsorb pharmaceuticals from the dissolved phase in comparison to surface sediment, and the organic carbon content in sediments emerged as a critical factor influencing the distribution behavior of pharmaceuticals. Suspect screening confirmed the presence of 170 compounds in the three environmental compartments, including 26 predicted transformation products found in this study and 144 reported pharmaceuticals and transformation products from previous studies. Based on the toxicological prioritization index score, diclofenac was ranked the top priority chemical of concern. The results underscore the estuary region of YRB as a pollution hotspot that gathers and transports pharmaceutical residues from upstreams into the East China Sea. Moreover, our findings provide a foundation for implementing pollutant control measures and effective environmental management strategies in this densely populated river basin.

Very-short-, short-, medium-, and long-chain chlorinated paraffins (vSCCPs, SCCPs, MCCPs, and LCCPs, respectively) were analyzed in specific tissue of paddy plants at four main growth stages and soils from the Yangtze River Delta, China throughout a full rice growing season. The total CP concentrations in the paddy roots, stalks, leaves, panicles, hulls, rice, and soils ranged from 181-1736, 21.7-383, 19.6-585, 108-332, 245-470, 59.6-130, and 99-400 ng/g dry weight, respectively. The distribution profile indicated the translocation of SCCPs and MCCPs from soils to paddy tissue, highlighting their elevated bioaccumulative potential. The evolution of CP level/mass/pattern during the whole growth cycle suggested atmospheric CPs deposition on leaves and hulls, as well as stalk-rice transfer. CSOIL plant uptake model well predicted the level, distribution pattern, and bioconcentration factors (BCFs) of SCCPs and MCCPs in paddy shoot and recognized the soil-air-shoot pathway as the major contributor. Moreover, risk evaluation indicated that MCCPs intake and subsequent risks dominated the total exposure to CPs via rice ingestion. This is the first report on the occurrence, fate and risk assessment of all CPs classes in paddy ecosystems, and the results underline the potential health effects caused by the in-use MCCPs via rice ingestion. © 2022, The Authors.
