The subway system is experiencing significant challenges from waterlogging due to climate change and urbanization, and the enclosed underground structure of the system makes the issue worsen. This study proposed the "Stability-Resistance-Recovery" assessment framework focused on subway system waterlogging resilience (SSWR), based on the system performance curve. This framework considered various factors, including inundation situation simulated by hydrological model, natural environment, subway information, and socio-demographic information. The case study in Beijing showed that the stability and resistance were the leading factors affecting the SSWR. Among all the indexes, water bodies surface percentage, evening peak departure time interval, and population density had the strongest impact on the SSWR. Generally, the subway system exhibited a relatively low level of SSWR, with 51.9% of stations indicating very low or low levels, mainly distributed on subway lines 1, 2, 4, 5, 7, 9, and 10. Stations at medium SSWR were dispersed throughout areas neighboring stations at very low and low SSWR. Stations at very high or high SSWR were minimal and scattered in peripheral areas. This research identifies the resilience level of subway station, and provides theoretical support for decision-makers to allocate waterlogging prevention and recovery resources. © 2023, The Authors.

Sulfur-containing and nitrogen-containing compounds are the major pungent odor compounds. However, those pungent odor compounds of microwave radish seed oil (MRSO) remain unclear. In this study, a total of 20 volatile sulfur-containing and nitrogen-containing compounds were identified using GC×GC-qMS, including 5 sulfides, 12 nitriles, and 3 isothiocyanates. Among them, the odor activity values (OAVs) of (methyldisulfanyl)methane, dimethyltrisulfane, (methylsulfinyl)methane, (methyldisulfanyl)(methylsulfanyl)methane, methyl thiocyanate, 5-(methylsulfanyl) pentanenitrile, and 4-isothiocyanato-1-butene to be higher than 1, which contributed most to the overall pungent odor of the MRSO. Moreover, 13 GSL were identified and quantified in five radish varieties by UPLC-IMS-QToF-MS, and glucoraphenin (GRE), glucoraphasatin (GRH), and glucoerucin (GER) accounting for up to 90 %. Total GSL decreased by 47.39−67.88% after microwave processing. The pungent odor compounds were primarily from of aliphatic GSL (GRE, GRH, and GER) degradation. This work provides a new insight into the odor contribution of GSL degradation products rather than nutritional properties. © 2022, The Authors. All rights reserved.

environmental DNA (eDNA) metabarcoding is a method that extracts species information from environmental samples, thereby aiding in the establishment or enhancement of biodiversity assessments. This study employed eDNA and Underwater Visual Census (UVC) to obtain baseline data on the biodiversity of Mischief Reef, explore the efficacy of eDNA in detecting functional organisms, and shed light on alterations in community structure and their contributing factors. Initially, we detected organisms at nine stations with eDNA and UVC in spring, detected 178 fish and macroinvertebrates (crustacean and mollusca) species by eDNA, 151 species by UVC, respectively. Furthermore, the functional biota detected via eDNA comprehensively covered the UVC approach, and the functional composition of common and endemic species discovered through UVC was similar, however, the functional traits of endemic species detected by eDNA fully covered those of common species. Thirdly, we used eDNA to discern biodiversity distribution patterns within high coral reef coverage (Hcrc) groups (19.5%) and low coral reef coverage (Lcrc) groups (8.79%), finding that taxonomic diversity (TD) and phylogenetic diversity (PD) followed the order TDHcrc>TDLcrc and PDHcrc>PDLcrc respectively. The non-significant difference in functional diversity (FD) between Hcrc and Lcrc indicated that Lcrc retained important functional organisms for ecosystem. Finally, our findings indicate a strong interaction between the environment and organisms, revealing that the coverage of reef-building coral is closely tied to surrounding biological resources. A stable sea surface seawater y velocity and a slight increase in seawater potential temperature were conducive to the survival of biological resources. Our study underscores eDNA effectively identifies functional organisms in coral reefs, reflecting ecosystem community structure differences. © 2024, The Authors. All rights reserved.

In order to solve the problems of pure cement slurry and cement water glass slurry in water-rich dissolution environment, such as uncontrollable setting time, poor slurry stability and durability, and slow growth of strength in the late stage of stone body, a kind of silica fume modified double liquid grouting material was developed. Based on orthogonal test and range analysis method, the action law of different water-cement ratio, silica fume dosage, cement-sodium silicate volume ratio, and polycarboxylate superplasticizer dosage on the working performance of silica fume modified double liquid grouting material was systematically studied to determine its optimal proportion. The optimized slurry was compared with pure cement slurry and cement-water-glass slurry in terms of working and durability properties, and microscopic test was conducted. The results show that: when the water-cement ratio is 0.8, the silica fume dosage is 12%, the volume ratio is 1.5:1, and the polycarboxylate superplasticizer dosage is 1.0%, the obtained slurry has the best working performance. The optimized silica fume modified double liquid grouting material belongs to Newtonian fluid with better fluidity. Its setting time, stability, 28d compressive strength, water corrosion resistance and permeability resistance are better than those of traditional grouting material. Microscopic analysis shows that the addition of appropriate silica fume in the silica fume modified double liquid grouting material can fill pores in the system, enhance the compactness of the slurry, and react with the hydration product calcium hydroxide to produce a large number of hydrated calcium silicate gel, enhance the mechanical properties and durability of the slurry. The proposed material provides some reference for the application of silica fume in the field of grouting materials. © 2024, The Authors. All rights reserved.

The climatic impact of the wastewater sector is significant given greenhouse gas (GHG) emissions through the whole supply chain. However, there has been a lack of investigation into trade-related leakage and the drivers of GHG emissions associated with wastewater treatment. Here, we develop a system-based modeling framework to track the outsourcing of emissions across regions, quantifying key socioeconomic drivers across the life-cycle stages of wastewater treatment in China, covering over 6,000 treatment plants nationwide. We find that outsourced emissions constitute over 41% of the total carbon footprint of China's wastewater sector. Over 90% of wastewater-related embodied GHG emissions traced back to production in northern, northwestern, and northeastern China. Variations in carbon intensity, production structure, and final demand structure can play an important role in emission reduction amid construction, treatment, and reuse stages. Our findings highlight the importance of coordinating supply-chain emission mitigation among regions for a deep decarbonization of the wastewater sector. © 2025 The Author(s)

Cr(VI) is toxic to the human body and environment. As a sustainable energy technology, constructed wetland-microbial fuel cells (CW-MFCs) can treat Cr(VI) wastewater while generating electricity. In this study, CW-MFC and constructed wetland systems were constructed to purify Cr(VI) wastewater. The removal mechanism of Cr(VI) was investigated using electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy. The results showed that the pollutant removal rate of the CW-MFC system is 2.99%–8.13% higher than that of the constructed wetland system on average. Moreover, the XPS and EPR analyses showed that Cr in substrates and Leersia hexandra Swartz mainly exists in the form of Cr(III). Additionally, in plants and substrates, the Cr(III) amount was found to be higher than that in the control group in the CW-MFC system, and the bioconcentration and translocation factors were 0.23 and 0.05 higher than those in the control group, respectively. Therefore, the CW-MFC system can efficiently remove Cr(VI) and promote the accumulation and transport of Cr. Overall, the results of this study provide a theoretical basis for the mechanism study of Cr(VI) wastewater treatment using CW-MFC systems. © 2022, The Authors. All rights reserved.
