Summary: Although there is increasing attention on particulate air pollution in the Taiwan Strait, there have been few studies focusing on the organic component of the pollution. This study conducted synchronous observations in Taiwan and Fujian to explore the chemical properties and sources of organic aerosols in the Taiwan Strait. The results showed that the organic constituents in the Taiwan Strait had relatively lower proportions of n-alkanes and PAHs, indicating less primary source contribution and more secondary formation influence. Cooking and vehicle emissions were found to be the main sources of organic carbon across the Taiwan Strait, followed by biomass burning and vegetative detritus. The contribution of biomass burning increased significantly when a large number of fire points were observed. The study highlights the chemical characteristics of organic aerosols in the Taiwan Strait and provides valuable information for pollution control policies.

Summary: Atmospheric rivers are efficient mechanisms that transport atmospheric moisture from low latitudes to the Antarctic Ice Sheet. They contribute substantially to Antarctic precipitation, particularly in East Antarctica. They play an important role in the year-to-year variability of Antarctic precipitation and are crucial for understanding present and future trends in Antarctic mass balance.

Summary: In this study, the strength of precipitation and its response to surface warming were examined using different atmospheric masses in a planetary climate system. It was found that precipitation is weaker when atmospheric mass is larger for a given surface temperature, and the increasing rate of precipitation with increasing surface temperature is smaller under a larger atmospheric mass. These findings have important implications for understanding the climate and habitability of early Earth, early Mars, and exoplanets with oceans.

Summary: The Greenland Ice Sheet is the primary source of global Barystatic sea-level rise, with at least half of its recent mass loss acceleration caused by surface meltwater runoff. Decade-long measurements from automatic weather stations in the most melt-susceptible regions identified dominant energy components and associated physical processes for surface mass loss. Surprisingly, large melt events only contribute 2% to total surface melt since 2007, with day-to-day variability dominated by sensible heat exchange and shortwave radiation.

Summary: This study focuses on the South Col Glacier located at the southern ridge of Mt. Everest, proposing that it is experiencing rapid mass loss. However, through comparison of aerial photographs and satellite data, the authors estimate a mean elevation change of 0.01 +/- 0.05m a(-1), contradicting the proposed mass loss. The study also investigates the surface energy and mass balance of the glacier and finds wind erosion to have a major impact on mass balance, and challenges the previous finding that melt is the dominant ablation process.

Summary: The study focused on the mass balance variation and drivers on the north-facing slopes of the Himalayas, particularly on the Naimona'nyi Glacier. It found that the annual mass balance was significantly correlated with annual precipitation and variability in melt energy. The increase in precipitation in the cold season and ablation season in the western Himalayas over the last two decades may be linked to various atmospheric circulation anomalies.

Summary: This study proposed a new operation mode of a water-based condensation particle counter called Scanning Flow Condensation Particle Counter (SFCPC). By altering the aerosol flow rate, this method can rapidly change the supersaturation, allowing for the evaluation of the inner supersaturation of particles. This method provides crucial chemical composition information of sub-10 nm particles for understanding atmospheric new particle formation and subsequent particle growth.

Summary: Micrometeorites undergo evaporation and atmospheric mixing during atmospheric entry, resulting in changes in their physicochemical properties and chemical isotopic signatures. Previous studies have estimated the extent of evaporation based on chemical and isotopic compositions, but a full integration of these proxies has not been successful. This study analyzed the compositions and iron isotope ratios of 57 chondritic cosmic spherules and found no correlation between chemical and isotopic fractionation. By measuring triple oxygen isotope ratios, a more accurate determination of parent body can be made. The results highlight the importance of iron isotope measurements in micrometeorite studies.

Summary: Tyre granulate used as infill for artificial turf is controversial, with some considering it a good example of reuse and others seeing it as a harmful way to dispose of discarded tyres. Due to loose application, the particles disperse into the environment, raising concerns about environmental and health impacts. This study aims to identify the pathways through which infill leaves a football turf and estimate the quantity of infill leaving the turf.

Summary: This study investigated the chemical transformation mechanisms of HULIS under different pH conditions using optical methods. The results showed that pH had a significant impact on the light absorption and fluorescence efficiencies of HULIS, with pKa as an important inflection point. The study also identified the acidic/basic groups in HULIS and found that the pH-sensitive species accounted for a certain percentage of HULIS-C.

Summary: This study reconstructed the annual and seasonal mass balances of Shiyi Glacier in the northeast Tibetan Plateau from 1963/64 to 2016/17 based on glacio-meteorological records and in-situ mass balance data, showing an overall downward trend in mass balance over the past 54 years, primarily due to temperature increases and prolonged ablation seasons. The research also found a close correlation between mass balance values and zonal wind speeds in the glacierized region, with the influence of macroscale circulation patterns being significant in the glacier mass balance dynamics.

Summary: In recent years, many wastewater treatment plants in China have been upgraded and reconstructed due to the improvement of emission standards. This paper proposes a novel process, the A(2)O-MBR-BAF-O-3 process, which can degrade COD, NH4+-N, TN, and chroma simultaneously. The experimental results show that this process can effectively remove these pollutants, and the effluent quality meets the national standards.

Summary: This study investigates the deterioration process of cement-based materials exposed to MgCl2 solutions under low air pressure conditions. It reveals a new corrosion mechanism, where the formation of Mg2(OH)3Cl.4H2O leads to intact surfaces but cracked interiors. The presence of Mg(OH)2 and M-S-H sediments significantly compromises the pore structure and compressive strength.

Summary: In this study, the effect of nano-SiO2 (NS) and nano-Al2O3 (NA) on the MgCl2 attack resistance of cement mortar under low air pressure and low humidity conditions was investigated. The introduction of NS/NA reduced the damage caused by the solution and decreased the number of harmful pores. The compressive strength of the nano-modified mortar was enhanced due to the nucleation effect and chemical activity of NS and NA, especially when NS was present.
