Summary: Sonoelectrochemical pollutant degradation is a promising method for water treatment, which combines both electrochemical and ultrasonic techniques to efficiently convert pollutants into harmless substances. The synergistic effects of electrochemistry and ultrasonication lead to faster degradation rates and improved mass transport, making it an attractive approach for pollutant removal in water.

Summary: Soil organic matter (SOM) is a crucial component of the global carbon cycle. This study focuses on mineral-associated organic matter (MAOM), which accounts for the majority of SOM in Earth's mineral soils. The authors propose a trait-based framework to understand the processes involved in MAOM formation and decomposition, and discuss how these processes can be influenced by climate change.

Summary: This study monitored the spatiotemporal trends of persistent organic pollutants (POPs) contamination along the Korean coasts using black-tailed gull eggs. The results showed higher levels of emerging POPs, such as brominated flame retardants (BFRs) and perfluoroalkyl acids (PFAAs), in eggs from certain areas influenced by urban pollution characteristics. The study highlighted the importance of continuous monitoring of PFAAs in the marine environment of Korea.

Summary: Anthropogenic climate warming is expected to increase the frequency of extreme hydrological droughts globally. This study integrates climate experiments, hydrological models, and multivariate analysis to examine the evolving characteristics and mechanisms of hydrological droughts. Results show that extreme hydrological droughts are projected to occur more frequently across catchments in different climate zones. Precipitation stress is currently the primary driver of historical droughts, but with climate warming, air temperature variations may become the new primary driver in high-latitude cold catchments.

Summary: Data on GHG emissions from the global food system are often scattered and unavailable, but EDGAR-FOOD provides a consistent database from 1990 to 2015. The largest contributions to food-system emissions come from agriculture and supply chain activities, representing 34% of total global GHG emissions.

Summary: This study investigated the distribution of persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) in the sediments of dams and ponds in Canakkale city, Turkey. The results showed varying concentrations of PAHs, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polychlorinated dibenzo-p-dioxins/furans (PCDD/Fs) in the sediments. The distribution of HMs in sediments was also observed. The study also analyzed the possible sources of these pollutants using diagnostic ratios and found that anthropogenic input is the main source.

Summary: Climate models predict an intensification of extreme precipitation under climate change, but this effect is difficult to detect in the observational record. Using machine learning methods, a physically interpretable anthropogenic impact on extreme precipitation is found in global observational data sets.

Summary: The study quantifies the importance of internal climate variability (ICV) in relation to anthropogenic climate change (ACC) using a criterion of time of emergence (ToE), showing that ToEs for annual mean precipitation and temperature are influenced by ICV and the choice of SMILE. While ACC is expected to emerge within this century in certain regions, there is uncertainty related to the choice of SMILE.

Summary: This review discusses the use of nanotechnology for the remediation of persistent organic pollutants (POPs). It emphasizes the importance of nanocatalysis, nanofiltration, and nanoadsorption processes. Nanoparticles such as clays, zinc oxide, and iron oxide have shown high efficiency in removing POPs. Nanofiltration and ultrafiltration have also shown potential in POPs remediation. Future research will address the cost issue of nanotechnology and make it a sustainable solution for POPs.

Summary: This study analyzed the concentrations of polycyclic aromatic hydrocarbons (PAHs) along a cross-section from China to Antarctica, revealing their spatial distribution, source contributions, and gas-particle partitioning in the Pacific, Indian, and Southern Oceans. The results showed that the sources and temperature of air masses significantly influenced the distribution of PAHs, with coal combustion emissions being the major source.

Summary: Sub-micrometer aerosol particles were collected from the chimneys of different power plants and boilers on the Svalbard archipelago. The dominant particle group was found to be soot, with significant variations in the relative abundance of fly ash spheres and mineral particles. The particles from coal burning had different chemical compositions compared to those from diesel burning.

Summary: This study measured the levels of perfluoroalkyl acids (PFAAs) in a firn core collected from Dronning Maud Land in Eastern Antarctica. The results showed an increasing accumulation of PFAAs in the snow over time, particularly for perfluorooctanoate and nonanoate, indicating a lack of decline in their production despite global curtailments. The study also found a marked increase in perfluorobutanoate levels since 2000, possibly due to chlorofluorocarbon replacements.

Summary: We studied the impact of partial dissolution on the transportation of chemicals in sea ice. A brine convection model that accounts for decoupling of chemicals from convecting brine was developed and evaluated using observational data. Different decoupling schemes were tested, and it was found that decoupling based on a constant fraction of brine concentration or proportional to brine salinity showed better performance in agreement with observations. Our findings reveal that decoupling from convecting brine can enrich chemical concentrations in growing sea ice, highlighting the usefulness of brine convection modeling in studying complex chemical behaviors in sea ice.
