Summary: The study compared trace metal concentrations in tissue of Mediterranean mussels and Olympia oysters at different sites in Puget Sound, Washington to understand differences in bioaccumulation based on species, location, and shellfish size. The research found that metal concentrations in shellfish varied between sites and were influenced by factors such as water chemistry and shellfish size.

Summary: The evaluation of PAH in the Sergipe-Poxim estuarine system showed low contamination levels, with naphthalene, dibenzo(a,h)anthracene, and pyrene as the prevailing compounds. Different media in the estuarine system showed varying levels of PAH content and risk quotient, with some bioaccumulation observed in the ecosystem.

Summary: This study presents an analysis of upper ocean deoxygenation in recent decades, finding spatially divergent evolution of O2 trends across different models. Comparisons between different configurations suggest that differences in atmospheric forcing and background mean states contribute to the divergent simulations.

Summary: The Southern Ocean is an important region for absorbing and storing anthropogenic heat. This study focuses on the south Indian Ocean and finds distinct warming minimum/cooling and freshening in the subtropical ocean thermocline. The freshening anomaly is advected to the north and subducted into the ocean interior, leading to fresher, deeper, and cooler isopycnal surfaces. This has implications for the future heat storage in the Southern Ocean.

Summary: Global warming is approaching the targets set by the Paris Agreement of 1.5 degrees C/2 degrees C temperature increase above pre-industrial levels. The time to reach these targets varies among climate models, but our study shows that a 2 degrees C global warming is closely linked to the state of the Southern Ocean and the amount of low-level clouds. Climate models that accurately simulate the initial Southern Ocean state can improve projections of 2 degrees C warming with reduced uncertainties.

Summary: The study found that different sizes of PtNPs have an impact on the uptake and elimination in Leptocheirus plumulosus, with mass and number-based uptake increasing with decreasing PtNP size, while mass and number-based elimination increasing with increasing PtNP size. The findings suggest that in a polydispersed NP suspension, the uptake of a given size fraction is independent of other size fractions in the mixture.

Summary: The ocean serves as a major sink for anthropogenic heat and carbon, but the trajectories of heat and CO2 uptake diverge over the 21st century due to regional differences in physical and chemical drivers. Regional variations in heat-to-carbon uptake ratios will result in coherent regional patterns for sea surface warming and acidification by the end of this century.

Summary: Ocean warming and acidification pose a severe threat to pteropods in the Arctic by reducing their survival and causing the dissolution of their shells. Lipids, especially phospholipids, play a crucial role in the early-stage pteropods. Our experimental study shows that elevated temperatures and high CO2 concentrations lead to a significant decrease in total lipids, mainly due to the reduction of phospholipids. This reduction may compromise cell differentiation and energy balance in the early-stage larvae. The negative effects of warming on lipid metabolism may be a more immediate threat to pteropods than shell dissolution effects caused by acidification.

Summary: Understanding the effects of OA and warming trend on marine organisms, particularly on early reproductive traits, is vital for predicting their response to climate change. In this study, exposure to elevated pCO(2) and higher temperatures had significant impacts on the sorus photosynthetic performance and germination rate of meiospores in Lessonia trabeculata, indicating potential threats to the species' establishment and ecosystem functioning.

Summary: Hard corals are declining while soft corals are increasing due to global and local factors. A study showed that the pulsating soft coral Xenia umbellata has a high resilience to ocean warming, and phosphate enrichment can enhance their resilience and possibly lead to their dominance over hard corals in the future.

Summary: The study investigated the responses of Philippine coral reefs to ocean warming and acidification scenarios, finding that changes in seawater temperature and pH have significant impacts on the growth and photosynthetic efficiency of F. colemani. Despite experiencing declines in growth rate and zooxanthellae density, F. colemani showed sustained photosynthetic competency under near-future scenarios, indicating its ability to adapt and survive in changing ocean conditions.

Summary: The study found that water samples kept in the dark and chilled did not show a significant decrease in eDNA detection or concentration compared to samples filtered immediately, while samples exposed to light and ambient air temperature showed rapid degradation of eDNA. This has important implications for fieldwork without immediate refrigeration and highlights the need for further research on eDNA degradation mechanisms and sample storage.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
