Thermal remediation is an effective technology for organic contaminant remediation. However, the application of thermal remediation may have negative effects on soil properties and ecological functions, which requires further investigation. Based on a pilot test of electrical resistance heating remediation (ERH), soil samples were collected at different locations after heating for 116 days. Most soil physicochemical properties except total organic carbon were less affected by the heating temperature difference. Application of high temperature increased microbial abundance but inhibited alpha diversity of the bacterial community. More significant changes in microbial communities were observed at temperatures above 60°C. The genera mainly affected by heating temperature included Flavobacteria, Brockia, and S085, while the increase in temperature also inhibited the abundance of nitrochlorobenzene functional genes. At 140 days after the end of the pilot test, the bacterial community affected by thermal remediation could recover effectively, and the recovery of the bacterial community was not affected by temperature difference during the heating period. This study provides valuable field evidence of the long term impact of soil ERH treatment on soil properties and microbial communities, and provide further references for optimization of remediation performance with coupled technologies. © 2024, The Authors.

Regional transport of air pollutants is a serious challenge to outdoor O3pollution control. Characterizing the transport of air pollutants by traditional air quality models heavily relies on accurate precursor emission inventories, chemical reaction mechanisms, and meteorological factors. In this study, the pollutant concentrations of upwind cities were incorporated as features into a random forest regression model (Traj-RF) to investigate the contribution of regional transport to local O3pollution. Hainan island was selected as the target area in this study, due to its air quality being affected significantly by regional transport. The Traj-RF model shows good predictive performance for O3with a coefficient of determination (R2) of 0.68 on the independent test set based on only observed air pollutants concentrations and meteorological data. The results of the Traj-RF model show that direct O3transport from upwind areas contributes approximately 27.5% to the O3concentration in Hainan, effectively highlighting the substantial role of regional transport in Hainan’s O3pollution. This refined machine learning method may have the potential to assess the impact of pollutant transport on regional air quality.

Flooding followed by drought in urban and forest soils:unraveling microbial dynamics and ecological functions

Dear Editor,Cities are among the most drought-prone areas globally. Meanwhile, the Chinese urban coastal areas face frequent flash droughts and also heightened flood risks,characterized by extreme precipitation and heatwave events exacerbated by tropical intraseasonal oscillations and meandering subtropical currents (Lai et al., 2024; Yuan et al., 2023). Anthropogenic-induced climate change has increased the probability of simultaneous flooding and drought events by tenfold, a trend expected to continue well into the future (Qian et al., 2023). However, there is a significant gap in understanding the effects of compound extreme climate events, challenging urban ecological governance. As a driver and regulator of elemental biogeochemical cycles, the soil microbiome is fundamental to the functional responses of urban ecosystems,including greenhouse gas emissions, organic matter decomposition, and accumulation (Fan et al., 2023). Compared with their natural counterparts, urban soil microbiomes feature an enhanced proportion of genes linked to greenhouse gas tolerance, faster nutrient cycling, and more intense abiotic stress responses caused by a richer history of extreme weather or greater environmental stresses(Delgado-Baquerizo et al., 2021).

Excessive carbon dioxide (CO2) emission has been challenges to regional sustainable development. In this study, an ecological-network input–output clustering (ENIOC) model is developed to analyze CO2 emission system. ENIOC can recognize the complex characteristics and relationships within CO2 emission system from network and statistical perspectives. ENIOC is applied to Jiangsu. Some major findings are as follows: (i) electricity-heat supply and metal smelting industries are dominant CO2 emission contributors (i.e., 16.4% and 12.3% of the total CO2 emission, respectively);also, they provide plenty of carbon-intensive products for supporting construction and heavy industries;(ii) the CO2 emission system is relatively unstable;optimize the structure of key pathways (e.g., mining → metal smelting → metal products) could mitigate CO2 emission across the supply chain;(iii) CO2 mitigation policy should focus on the sectors in cluster 2 (e.g., chemical, metal product and equipment industries) to reduce their dependency on carbon-intensive products from other sectors;CO2 mitigation policy also should focus on metal smelting and electricity-heat supply industries (i.e., the sectors in cluster 3) to improve their efficiencies of energy use. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Sulfur mustard (HD), a highly toxic vesicant used as a Chemical Warfare Agent (CWA), can remain for a few weeks once leaked into the environment. This work investigated the mass uptake of sulfur mustard vapor on thin water and ice films as well as air-water/ice interfacial and bulk partitioning of sulfur mustard under several typical environmental conditions by using a flow tube reactor. The partition constant of sulfur mustard in the sea water was close to that of pure water, and greater than that in the river water. The effects of water properties (including salinity, humic -like substance contents, and surface tension) on the air-water partitioning of HD were investigated. The adsorption enthalpies and entropies of HD uptake in thin water film were obtained from the temperature dependence was 20.76±1.08 kJ/mol and 71.58±3.91 J/mol. The quasi-liquid layer on the ice surface appeared to play a crucial role in the adsorption process as the ice thickness decreased. The data collected in this study are essential in developing effective strategies for managing and mitigating the risks associated with the leakage of chemical warfare agents containing sulfur mustard. © 2023, The Authors.
