Summary: Understanding the accumulation and transport of nutrient and pollutant elements (NPEs) in the Thames River watershed, Connecticut, is crucial for protecting water resources and aquatic ecosystems. This study found that arsenic concentrations in soil and sediments exceeded quality targets, but not river water. Riparian soil and land cover were not strong predictors of NPE concentrations in sediments and river water. Dissolved export of NPEs was greater than sediment export for most elements. Watersheds with higher farmland had higher phosphorus concentrations in river water. Overall, NPE export has decreased but remains above baseline throughout the Thames River watershed.

Summary: In this study, the relationship between Kashin-Beck Disease (KBD) and the hydrochemical characteristics of surface waters was comprehensively investigated. The results indicate that surface waters in KBD endemic areas have lower pH, total hardness, total dissolved solids, and oxidation-reduction potential compared to non-endemic areas. Long-term consumption of water deficient in essential trace elements and enriched with potential toxic elements likely causes KBD. Environmental factors and poisoning by food fungi toxins and water organic compounds may also impact the occurrence of KBD.

Summary: The study reveals that the subsurface of Jezero crater is primarily composed of volcanic and intrusive terrains with compositional and density stratification. Basaltic rocks with higher plagioclase content are found in higher stratigraphic locations, while layered rocks with more normative pyroxene are found in lower stratigraphic layers. The lowest observed unit with the highest inferred density is olivine-rich and shows characteristics of cumulate origin. The presence of alteration materials suggests relatively brief lacustrine conditions. Orbital observations connect the lithology of the Jezero floor to the broader Nili-Syrtis region, indicating regional density-driven compositional stratification.

Summary: The presence and geochemical composition of olivine on Mars are important for studying the planet. Raman spectrometers, used in Mars 2020 and future missions, provide new possibilities to determine the Mg/Fe ratios in olivine-bearing rocks. Olivine's presence indicates past volcanic activity on Mars, and its forsterite/fayalite ratio can reveal information about the origin and evolution of the parent magma. This study proposes a new calibration model using Raman spectroscopy, greatly improving the accuracy and uncertainty associated with the forsterite/fayalite ratios compared to previous literature.

Summary: Soluble salt analysis is crucial for evaluating the conservation status of built heritage. However, current European norms only include a few anions, undervalue cations, and do not require simultaneous analysis. This study demonstrates that quantitative analysis of anions and cations is crucial for understanding the conservation status of historical buildings undergoing conservation work. Ionic chromatographic system was developed to analyze anions, cations, and carbonate/bicarbonate simultaneously, and was applied to examine brick and mortar samples in Punta Begon & SIM;a Galleries.

Summary: The Vistula Lagoon, one of the two lagoons on the Polish coast, is economically and environmentally significant. This study aims to calculate the water balance of the lagoon before and after the construction of a canal through the Vistula Spit. The construction of the new connection may impact the lagoon's water balance and its biotic and abiotic environment. Data on precipitation, evaporation, inflow from the catchment, and inflow/outflow through the Strait of Baltiysk were collected for mathematical modeling. The study suggests that the construction of the new canal will not significantly alter the lagoon's water balance but may cause environmental problems.

Summary: We demonstrate that wind-driven Ekman transport enhances the advection and mixing of cells, leading to the transport of colder water from the Surface Antarctic Waters to the warmer waters of the northern Polar Front belt. This mechanism provides cells with a favorable temperature environment, allowing for specific species and community growth rates to develop blooms under non-light limiting macronutrients and iron conditions. Our findings have important implications for increased productivity in a future warming climate.
