Summary: The study highlights the potential risk for drinking water provision in Scotland from peatlands due to climate change, urging the need for frequent monitoring and necessary mitigation measures. Variability among catchments shows some may face substantial seasonal increase in DOC levels. Peatland restoration could be useful in counteracting the projected DOC increase and ensuring safe drinking water provision.

Summary: DOC and DON concentrations in streams show different trends in various biomes and the DOC:DON molar ratios increase over time. The recovery from atmospheric acid deposition leads to fundamental changes in the DOM pool, affecting biogeochemical processes and food webs in streams.

Summary: The text discusses the transformation and sequestration of organic carbon produced in the sunlit surface ocean into the ocean's interior, focusing on the refractory dissolved organic carbon (rDOC). It emphasizes the importance of defining rDOC operationally and highlights the various factors influencing its persistence, including intrinsic and extrinsic properties. The text also suggests specific research questions aimed at stimulating further research on the nature, dynamics, and role of rDOC in carbon sequestration under future scenarios of climate change.

Summary: Atmospheric acid deposition has disrupted carbon cycling in lakes, leading to a decrease in dissolved organic carbon (DOC) loads. However, in lakes heavily affected by acid deposition, the organic carbon accumulation rate (OCAR) has not changed significantly. Unlike other northern forest lakes, these lakes have not experienced significant changes in organic carbon accumulation during recovery from acid deposition.

Summary: Estuaries and their catchments play a crucial role in the cycling of dissolved organic matter and nutrients, with ICOLLs impacting the biogeochemical processes and release of nitrogen and carbon into coastal environments. Despite low inorganic nitrogen concentrations, the eutrophic ICOLL studied in southwest Australia experiences issues such as algal blooms and low dissolved oxygen, highlighting the importance of considering dissolved organic nitrogen in nitrogen studies. Including dissolved organic nitrogen in nitrogen studies may have a significant impact on the current understanding of the global nitrogen budget.

Summary: Climate change and nitrogen and sulfur deposition have significant impacts on forest demography. The study projects changes in forest composition based on future scenarios of temperature, precipitation, and deposition. Results show that the effects of climate change and deposition vary among species, with potential shifts in the abundance of 60 species declining and 20 species increasing. The study suggests that reducing deposition alone may not be sufficient to offset the impacts of climate change on forest composition.

Summary: Changes in anthropogenic activities have affected the speciation and concentration of reactive nitrogen delivered to coastal and oceanic waters through precipitation. However, the knowledge about dissolved organic nitrogen (DON) in rainwater is limited, despite its importance and potential contributions to primary and secondary production. A study in Delaware, USA, found a decrease in rainwater nitrogen and carbon amounts between 1994 and 2019, with the major reduction observed for nitrate. Season, airmass back trajectory, rainfall amount, and meteorology influenced the amounts of nitrogen. DON had different seasonal patterns compared to inorganic nitrogen and dissolved organic carbon, suggesting a biological source. The findings highlight the dynamic nature of atmospheric fluxes and the need for reevaluating models of atmospheric deposition to accurately assess inputs from changing atmospheric sources.

Summary: The study simulated soil emissions of NO and N2O from typical land uses in Lowland and Highland Scotland under climate change conditions. Results showed that natural moorlands with high NH3 deposition rates were the main sources of NO emissions. As combustion sources of NO (x) decrease, the impact of soil NO emissions is likely to increase.

Summary: The study found significant differences in water quality among lakes in the Athabasca oil sands region, where some lakes were affected by atmospheric deposition from oil sands operations leading to lower pH levels, while others were influenced by groundwater inputs showing better buffering capacity.

Summary: Shifts in hydroclimatic regimes associated with global climate change can impact freshwater availability and quality. This study used a dynamic modeling approach to simulate streamflow and carbon export in a northern Canadian catchment under different climate scenarios. The results showed that average discharge is predicted to decrease under elevated temperature but increase under elevated temperature and precipitation scenarios. Similarly, carbon export is expected to decrease with only elevated temperature, but increase significantly with elevated temperature and precipitation scenarios. These predicted changes in carbon export highlight the need for additional monitoring efforts in the region.

Summary: Mercury mining in southwest China may have started before the establishment of the Qin dynasty, around 2500 years ago, potentially motivated by climate changes and human industrial activities. Two major peaks of mercury deposition were observed in the past 10,000 years, coinciding with critical climate changes. This study highlights the significance of climate variability and local mercury mining in controlling global atmospheric mercury deposition during the Holocene.

Summary: Monoaminoacridines were studied as potential matrices for MALDI(-)-MS analysis, with 3- and 4-aminoacridine showing superior performance in obtaining acceptable spectra. The compounds were characterized for their spectral, proton transfer-related, and crystallization properties, and a novel algorithm was developed for MS data analysis. All five studied aminoacridines were found to be suitable as matrix materials, with interesting results showing the benefits of using a small amount of matrix material mixed with an excess amount of sample in obtaining the best mass spectra.

Summary: Multidimensional fluorescence spectroscopy is evaluated as a non-invasive and non-destructive method for analyzing components in natural textile dyes. The study demonstrates that natural dye components fluoresce and wool's intrinsic fluorescence is not a significant interference in most cases.
