Here, microbial drivers of DOM removals and greenhouse gas (GHG) emissions were explored in CEWWTP of a large-scale coal industrial park. Five fluorescence components (C1-C5: aromatic macromolecular-like, naphthenic-like, fulvic-like, phenolic-like and tryptophan-like) and three functional groups (amine, phenolic and aromatic) were identified from DOM in CCW. C1, C2 and C4 accounting for 74.85 % of all components, were mostly degraded in anaerobic and ozone oxidation tanks. The rate of N<sub>2</sub>O emission reached the peak (1241.76 mmol m<sup>-2</sup> h<sup>-1</sup>) in the 1st anoxic tank, where removal efficiencies of all components were less 10.00 %. Based on hetero 2D-EEM/UV-COS, the varying order of DOM fractions and functional groups was amine→C5→C4→phenolic→C2→aromatic→C3→C1, suggesting that amine and phenolic be intermittently degraded along with tryptophan-like and phenolic-like, while aromatic be consecutively degraded along with fulvic-like and aromatic macromolecular-like. According to structural equation model, ORP and pH showed positive effects (β = 0.71) on bacteria, while DO exhibited an inverse effect (β = -0.70). Certainly, ORP, pH and DO were the key drivers of influencing abundance and diversity of bacteria, e.g., Zoogloea and Actinobacteria. Bacteria had indirect positive effects on GHG emissions by conventional pollutants or by DOM fractions. This suggested that organic matter decomposition by bacteria should yield CO<sub>2</sub> via respiration or serve as an energy source for denitrifying bacteria to produce N<sub>2</sub>O.

FSY application and rice growth stage were the core factors that significantly reshaped bacterial and archaeal community structures, shifting archaeal community assembly toward deterministic processes, while the fungal community remained relatively stable.

It reveals that the global frequency and intensity of heatwave events show an increasing trend. During heatwave events, temperature, humidity, solar radiation, and atmospheric circulation factors exert notable influences on ozone (O<sub>3</sub>), nitrogen-containing pollutants, and secondary particulate matter. O<sub>3</sub> concentrations exhibit a positive correlation with temperature during heatwaves, however, the rate of increase slows down or is even suppressed under extreme high temperatures (O<sub>3</sub> suppression). Heatwaves promoted the generation of nitrogen-containing pollutants, particularly reactive nitrogen through localized diffusion control, high temperatures, wildfires, and intense solar radiation. Secondary organic aerosol (SOA) formation relies on the photochemical oxidation and heterogeneous-phase reaction, with the contribution of isoprene weakening and that of terpenes enhancing under high temperatures. Heatwaves influence nitrate and sulfate in different ways: the former tends to exist in gas phase due to high temperature, while the latter is influenced by the combined effects of temperature and humidity. During heatwaves, high temperatures and O<sub>3</sub> exert extensive negative effects on human health resulting in risks of cardiovascular and respiratory diseases, heatstroke and neurological abnormalities.

Functional genomics revealed upregulated glycolysis, TCA cycle, and nitrate to ammonium genes under FBC. MBC activated denitrification, removing nitrate effectively but causing nitrogen loss that limited chlorophyll synthesis. Iron oxide types critically influenced soil-plant-microbe interactions, with FBC balancing nutrient regulation, stress tolerance, and microbial-driven carbon/nitrogen cycling. This study revealed the effects of iron oxide types on soil-plant-microorganisms, and provided an integrated improvement strategy for coral island ecological restoration that balanced nutrient regulation, stress tolerance enhancement, and microbial function strengthening.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"122979"},"PeriodicalIF":7.7,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145205161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
