Oxygenated (CHO) and nitrogenous (CHON) organic aerosols (OA) are important components of fine particulate matter (PM2.5) in urban environments. To achieve a molecular-level understanding of the seasonal variation of the OA fraction, ambient PM2.5 samples collected from April 2018 to March 2019 in Xi’an, Northwest China, were analyzed using an iodide Chemical Ionization Mass Spectrometer combined with a Filter Inlet for Gases and AEROsols (FIGAERO–CIMS). The set of compounds identified by FIGAERO–CIMS was estimated to represent 28.6% of the organic matter in PM2.5. Evaporation temperatures measured by FIGAERO–CIMS indicated that semivolatile organic compounds (SVOCs) were dominant among the identified analytes. Concentrations of CHO (6.01 ± 4.24 μg m–3) and CHON (3.17 ± 2.34 μg m–3) increased in winter, especially during a severe haze episode in January 2019. The CHO compounds comprised up to 75.3 ± 3.2% of the total detected compounds. The average carbon oxidation state (¯OSC) was slightly elevated in the summer samples. The CHON compounds were mainly nitro-aromatics and their abundance increased substantially in winter, which was attributed to extensive biomass burning demonstrated by high levels of levoglucosan. Biomass-burning related sources accounted for 61.0 ± 19.6% and 68.3 ± 21.9% of the total CHON concentration in autumn and winter, respectively, while secondary formation was the dominant source of CHON species in spring (70.1 ± 11.6%) and summer (79.8 ± 7.0%). These results emphasize the importance of secondary formation and biomass burning as sources of OA components and reveal a clear need to control biomass burning used for heating in Xi’an and its surroundings.

The mechanism of the reaction between CO2 and OH– (anion) in ice cluster models was determined using density functional theory (DFT), employing the ωB97X-D functional and def2-TZVP basis sets for all atoms. A range of reaction barriers, 0.08–0.43 eV, were found, and the lowest energy path has a barrier of 0.08 eV, giving rise to the bicarbonate ion (HCO3–). Computed rate constants, accounting for quantum tunneling by employing the Eckart potential, suggest that the CO2 + OH– → HCO3– reaction can operate in ice at low temperatures (e.g., 10 K). In contrast, relatively high reaction barriers (0.52–0.74 eV) were found for the CO2 + OH• (radical) → HCO3• (radical) reaction, and the computed rate constants at low temperatures (e.g., 10 K) are extremely small. Based on the computed data, we argue that OH– can react with CO2 trapped in interstellar ice at 10 K, and the product of the reaction, HCO3–, is stable in ice. On the other hand, the OH radical does not react with CO2 in ice. Therefore, we propose that OH anions in interstellar ice play a role in the formation of precursors of complex organic molecules (COMs) in the interstellar medium. The present findings will open a new dimension to explore the chemical evolution in the interstellar medium through the chemistry of anions in interstellar ices.
利用密度泛函理论（DFT）确定了冰簇模型中二氧化碳和OH-（阴离子）的反应机理，所有原子均采用ωB97X-D函数和def2-TZVP基础集。研究发现了 0.08-0.43 eV 的反应势垒范围，最低能量路径的势垒为 0.08 eV，产生碳酸氢根离子 (HCO3-)。利用埃卡特电势计算量子隧穿的速率常数表明，CO2 + OH- → HCO3- 反应可在低温（如 10 K）下在冰中进行。相反，我们发现 CO2 + OH- （自由基） → HCO3-（自由基）反应的反应势垒相对较高（0.52-0.74 eV），而且在低温（如 10 K）下计算出的速率常数极小。根据计算得出的数据，我们认为在 10 K 的温度下，OH- 可以与星际冰中的 CO2 发生反应，而反应产物 HCO3- 在冰中是稳定的。另一方面，OH 自由基不会与冰中的 CO2 发生反应。因此，我们认为星际冰中的 OH 阴离子在星际介质中复杂有机分子（COMs）前体的形成过程中发挥了作用。这些发现将为通过星际冰中阴离子的化学性质来探索星际介质的化学演化打开一个新的局面。

Understanding how artificial anaerobic environment (flooding) affects paddy soil ecosystem carbon (C) sequestrating has become imperative in the context of global climate change. However, the specific effects under various types of flooding management remain unclear. Here, we reported the results of 682 paired observations from 166 field experiments across typical rice-planting regions in China with a strong environmental gradient, with flooding effects on soil organic carbon (SOC) remaining relatively consistent. Accordingly, we employed nonmetric multidimensional scaling (NMDS) to categorize annual flooding periods into short (3–5 months) and long term (>5 months). The results showed that long-term flooding (48.52 Mg ha–1) had a greater SOC sequestration capacity than short-term flooding (30.43 Mg ha–1). Furthermore, the application of structural equation modeling (SEM) revealed that long-term flooding significantly mitigated the impacts of mean annual temperature (MAT) and mean annual precipitation (MAP), reducing them by a substantial 7.73-fold compared to short-term flooding. Briefly, longer submerged environments in long-term flooding mitigated the positive effects of MAT and negative effects of MAP, with the standardized total effects (STEs) of 10.7 and 6.2% (P < 0.05), respectively, which were much smaller than those under short-term flooding (21.3 and 67.8%, P < 0.05, respectively). Our findings highlight that an understanding of the relative contribution of anaerobic environment induced by artificially flooding to SOC in soil ecosystems is critical for guiding management efforts aimed at maintaining ecosystem SOC sequestration under global changes.

The reduction of HgII to HgI or Hg0 can lead to significant changes in Hg toxicity and mobility in the environment. Photochemical reduction is the primary process for the reduction of HgII to Hg0 in sunlit environments; however, dark reduction of HgII can occur via microbial metabolic processes and/or reduction by reduced natural organic matter, FeII mineral phases, FeII sorbed to minerals, or aqueous FeII. Here, we demonstrate a novel HgII reduction pathway involving another environmentally relevant reductant, MnII. Abiotic reduction of HgIIO by MnII was studied as a function of pH and anion environment (perchlorate, sulfate, chloride) using X-ray absorption spectroscopy to characterize the solid-phase Hg and Mn species. At circumneutral pH of 7.5, about 70% of HgII was reduced to elemental Hg0 within 2 h. In contrast, 12 h were needed to achieve the same extent of reduction at pH 6.9. In the presence of sulfate and chloride, HgI species were formed. HgII reduction was initially rapid and coupled with the oxidation of soluble MnII-oxides to insoluble MnIV-oxides, followed by a significantly slower reduction of HgII during the MnII-catalyzed transformation of the MnIV-oxides to hydroxide and oxyhydroxide minerals. The observed reduction of HgII by MnII at circumneutral pH could be an important transformation pathway for environmental Hg, affecting its bioavailability and mobility under mildly reducing conditions.
