Summary: Polycyclic aromatic hydrocarbons (PAHs), known for their recalcitrant properties and biotoxicity, pose serious environmental and health problems. Accurate determination of the bioavailable fraction is crucial for evaluating the toxic potential of these compounds. This study employed different types of passive samplers (LLDPE and LDPE) to determine the freely dissolved concentrations of PAHs using performance reference compounds in three different bodies of water. The results showed that LLDPE is a suitable alternative to LDPE for monitoring PAHs in both short-term and long-term studies.

Summary: This study demonstrates the feasibility of using quartz wool disk passive air samplers to identify and quantify nitrate concentrations and their isotopic compositions. The results show that nitrate concentration is largely influenced by regional economic development, while the regional distribution of nitrate isotopes is affected by source changes. Coal combustion and mobile sources contribute significantly to nitrate in urban areas, while biomass burning and biogenic soil emissions are more important in regions with high natural productivity and intensive agricultural activities.

Summary: Studies found that premetamorphic amphibians have higher metal concentrations than postmetamorphic ones, indicating that these metals can be largely excreted before or during metamorphosis. The concentrations of metals in the gut decreased from pre to postmetamorphic stages. Laboratory studies did not identify significant effects related to metamorphosis at concentrations below water quality standards, but delays in timing or growth were observed in field studies.

Summary: This study demonstrates the utility of synchrotron-based X-ray spectroscopic techniques in investigating the geochemistry of vanadium in ancient marine sediments. The results show that vanadium is primarily hosted by phyllosilicate-III and is strongly associated with potassium-rich clay minerals. The findings suggest that differentiating authigenic and detrital vanadium in ancient marine sediments may not be possible, which has implications for vanadium isotope system studies.

Summary: The availability of soil nitrogen for plant uptake can be affected by various soil factors, and conventional extraction techniques may affect the measurement of plant-available N concentrations. The diffusive gradients in thin-films (DGT) technique can overcome these limitations and has been successfully used to estimate the plant-available fractions of nutrients in soils. Therefore, evaluating the use of DGT for measuring NO3- and NH4+ in different soils and examining the factors affecting the plant-availability of these ions in soils is important.

Summary: The analysis of porewater concentrations in constructed wetland sediments using DET techniques revealed the sources and sinks of nutrients and their impact on water quality. Aeration of the water column improved oxygen levels and redox potential in the sediment, leading to decreased ammonium concentrations but increased phosphate and ferrous iron concentrations. Nitrate concentrations were below the detection limit, indicating limited nitrification-denitrification processes. The results highlight the usefulness of DET techniques in quantifying nutrient concentrations in constructed wetlands under different environmental conditions.

Summary: This paper presents the use of synchrotron-based X-ray techniques to investigate the vanadium host phases in ancient marine sediments. The results show that vanadium is mainly present as vanadium (III) hosted by phyllosilicate. Strong associations between vanadium and potassium suggest that vanadium is hosted by potassium-rich clay minerals. Differentiating authigenic and detrital vanadium in ancient marine sediments is unlikely due to similar chemical speciation for both fractions.

Summary: Gully erosion can significantly impact global river sediment budgets, with remediation efforts showing promising results in reducing suspended sediment and nutrient export. In a preliminary evaluation of landscape-scale gully remediation in the Great Barrier Reef catchment, a high level of financial and logistical effort was invested to develop long-lasting erosion mitigation measures. Water quality monitoring techniques, including a novel suspended sediment monitoring network, were used to compare remediated and control gullies, showing lower suspended sediment and nutrient concentrations in the remediated site. Long-term monitoring is necessary to validate the findings and demonstrate the potential of landscape-scale remediation as an effective mitigation action.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
