Summary: This research investigated the impact of atmospheric dry and wet deposition on particulate organic carbon (POC) in the coastal waters of Yangma Island in the North Yellow Sea. The findings showed that POC was primarily deposited through dry processes, accounting for 71.1% of the deposition. The total input of organic carbon (OC) from atmospheric deposition to the study area was estimated to be up to 12.0 g C m-2 a-1, indicating the important role of atmospheric deposition in coastal ecosystem carbon cycling. The contribution of atmospheric deposition to dissolved oxygen consumption in the seawater column was found to be lower than 5.2% in summer, suggesting a relatively minor impact on summer deoxygenation in the region.

Summary: This study established a sampling station in Dinghu Mountain to investigate the dry and wet deposition of atmospheric mercury in typical forest ecosystems in Southeast China. The results showed that wet deposition was the predominant form of deposition, and its flux was positively correlated with rainfall. The main sources of atmospheric mercury were soil dust and emissions from coal and fuel.

Summary: This study utilized three different membranes to quantify the concentrations of gaseous oxidized and particulate-bound mercury in the atmosphere, as well as to identify their chemistry. The research found that there is a gradient in concentrations of different compounds in different regions, and reactive mercury compounds from long-range transport can reach continental locations.

Summary: With the implementation of the Mercury and Air Toxics Standards and the Minamata Convention, mercury emissions have decreased in the United States. A national-scale effort was initiated to establish a baseline of mercury stable isotope values in order to study the changes in atmospheric mercury concentrations. The study found that unique mercury sources and environmental variables can impact total gaseous mercury isotope values, highlighting the importance of characterizing atmospheric mercury isotopes on a larger geographical scale.

Summary: Understanding sources and processes affecting atmospheric mercury (Hg) is essential for targeted Hg management. This study used stable isotopes and air trajectories to characterize sources and processes of total gaseous Hg (TGM) and particulate bound Hg (PBM) in a coastal city in South Korea. The results showed that TGM evasion from the coastal surface of the East Sea and high latitude regions are important sources, while PBM is mainly sourced from local anthropogenic emissions and undergoes Hg2+ photo-reduction on particles. The study also identified a regional isotopic end-member that can be used to quantify the relative influence of local anthropogenic Hg emissions and complex processes affecting PBM in East Asia and other coastal regions.

Summary: Eddy covariance measurements were conducted to assess the seasonal evolution of size-segregated aerosol fluxes above an oak-hornbeam forest in the Po Plain. The results showed that forest phenology and leaf presence/absence influenced the aerosol fluxes, with different size aerosols exhibiting different deposition and emission characteristics. Meteorological parameters and stomatal activity also played a role in aerosol flux.

Summary: Studying the sources of suspended particulate organic matter (SPOM) in reservoirs located in desert grassland areas is crucial for understanding the carbon and nitrogen cycles. This study focused on the impact of atmospheric deposition on reservoirs in regions with little rainfall and a dusty climate. Using isotope techniques, the study analyzed the composition and sources of SPOM in the reservoir and its watershed during dry and wet seasons. The results revealed that atmospheric deposition and terrestrial C3 plants were the main sources of carbon in SPOM, while atmospheric nitrogen deposition and soil erosion were the primary sources of nitrogen.

Summary: Monitoring gaseous oxidized mercury (Hg2+) accurately and with high time precision is a challenge in mercury research. Existing methods are not suitable for high-particulate environments. Researchers developed a new monitoring system, CSAMS, which combines a dual-stage cation exchange membrane (CEM) sampler with a commercial system and improves the accuracy of Hg2+ monitoring while also allowing measurement of Hg-0, Hg2+, and Hgp simultaneously.

Summary: A new chemical mechanism for the atmospheric cycling of Hg-0/Hg-I/Hg-II is proposed and implemented in a global atmospheric chemistry model for comparison with observations. The model successfully explains the oxidation and deposition processes of Hg in the atmosphere, with major uncertainties including the concentration of Br, stability and reactions of Hg-I, and speciation and photoreduction of Hg-II in aerosols and clouds.

Summary: The study highlights the importance of considering the dynamics of the total mobile inventory, including particulates >0.45 pm, in understanding carbon and elemental fluxes as well as nutrient cycles and subsurface ecosystem functioning. Seasonal and episodic dynamics of the total mobile inventory in undisturbed soil are influenced by atmospheric forcing, with episodic events like snow melts and rainstorms significantly contributing to the export of inorganic/organic matter beyond the subsoil-regolith boundary.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
