Summary: This study proposes a new method for assessing the vulnerability of coastal farmland systems to saltwater intrusion. The sensitivity of the farmland system was evaluated by combining the depth of the freshwater/saltwater interface and the electrical resistivity of the shallow subsoil. The results show that about 30% of the farmland is under strong and extreme conditions, 28% is between marginal and moderate, and 40% is under negligible vulnerability.

Summary: The main objective of this study was to estimate the van Genuchten-Mualem parameters and the saturated hydraulic conductivity of a low-lying farmland in Italy. Two methods, Ensemble Smoother and Levenberg-Marquardt algorithm, combined with hydrological modeling, were used for estimation. Results showed that Ensemble Smoother effectively reduced the uncertainty of alpha and n, but was less effective on theta r and Ks. Both methods were able to reproduce the volumetric water content observations, with Levenberg-Marquardt performing better in sandy soils and Ensemble Smoother performing better in peat soils. Ensemble Smoother was less time-demanding and less dependent on user choices compared to Levenberg-Marquardt. The paper emphasizes the importance of prior knowledge of the van Genuchten-Mualem parameters in defining optimization constraints.

Summary: This research examines the influence of sedimentary constraints on the salinity stratification of the unconfined aquifer at the southern margin of the Venice lagoon. The results show that the stratigraphic architecture of the subsoil determines the fresh-saltwater dynamics of the aquifer, and three different behaviors were observed. This characterization is crucial for planning mitigation measures to improve farmland productivity.

Summary: This study constructed and compared an improved DRASTIC model, including the DRASTIC-LTPD model and the AHP-DRASTIC-LTPD model, to assess the groundwater vulnerability around farmland area in Shuangsheng Industrial Park, Sichuan Province, China. The results showed that the vulnerability was higher in the central industrial park area and lower in the western and eastern farmland areas. The AHP-DRASTIC-LTPD model effectively reflected the impact of human activities and dilution on groundwater vulnerability and provided more reliable evaluation results compared to the other two models.

Summary: This study characterized foraminiferal biotopes in the soft bottom sediments of the Laizhou Bay-Yellow River Delta system, identified five biotopes, and assigned main species to four ecological groups based on their sensitivity/tolerance to stress. The Foram-AMBI index was defined using the relative proportions of species assigned to the ecological groups, allowing for the assessment of ecological quality status of marine soft-bottom habitats.

Summary: Global recognition of groundwater aquifer depletion and attention to land subsidence effects related to aquifer exploitation. Study developed LSIE index based on 10 land subsidence attributes and applied it to 113 sites globally. Findings show impact of LSIE varies with changes in natural processes, regulatory policy interventions, and groundwater usage, with effectiveness of interventions depending on aquifer lithology. Developing countries are more vulnerable to land subsidence due to lower water governance and institutional performance.

Summary: This study conducted a detailed geological analysis of coastal aquifers in South America, specifically focusing on the coastal plain of the province of Buenos Aires, Argentina. It found that the sand formations in this region have high permeability and storage capacity, leading to high concentrations of Fe and Mn in the regional groundwater, which exceed safe levels for human consumption. This poses a problem for water service providers and residents without access to a water supply network.

Summary: This study analyzes the role of the geologic-geomorphic setting in the Holocene evolution of the Rio de la Plata estuary in controlling the shape and distribution of freshwater lenses. The results show that the geological and geomorphological evolution of the estuary resulted in landforms that favor rainwater infiltration and the formation of freshwater lenses. This study highlights the importance of comprehensive analysis of the geological-geomorphic setting for exploring freshwater lenses in coastal areas.

Summary: The northern Adriatic Sea is home to unique rock formations that contribute to a diverse ecosystem not found on the sandy seabed. This study provides new insights into the lithification process of these formations through geological, geophysical, and mineralogical analyses. The findings suggest a common cementation process involving methane-derived carbonates, regardless of the depositional environment. This highlights the potential impact of methane seepage on greenhouse gas emissions.

Summary: This study collected four short sediment cores to investigate the effects of bay scallop farming on the composition and accumulation of sedimentary organic matter (SOM). The results showed that SOM primarily consisted of easily biodegradable substances, with a high contribution of biopolymeric carbon. Scallop farming areas had a higher sediment accumulation rate and greater burial fluxes of total organic carbon (TOC) and total nitrogen (TN) compared to non-scallop farming areas. The study also estimated the potential increases in TOC, TN, scallop-derived organic carbon, and marine algal-derived organic carbon in the scallop farming area with increased scallop production. Overall, this research highlights the significant impact of scallop farming on the biogeochemistry of SOM in coastal waters and provides valuable insights for future studies on carbon cycling in shellfish culture areas.

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.
