Summary: The study found that the input of forest litter into the soil may significantly increase the effects of toxicity. Waterlogged conditions facilitated a release of As into pore water, and the addition of forest litter accelerated this effect thus causing increased toxicity.

Summary: Several studies have shown that effluent discharges can contaminate waterways. However, the impact of chemical pollutants on sediment, especially from an ecotoxicological perspective, is not well understood. This study compared water-sediment samples from high-anthropogenic urban areas and low-anthropogenic peri-urban areas. The results suggest chronic toxicity effects in the samples collected from the high-anthropogenic urban area, while no acute toxicity was observed in both areas.

Summary: Reservoir sediments can act as a sink for radionuclides, but in anaerobic conditions, Cs-137 can remobilize from sediments to water columns in bioavailable form. This study found that in highly contaminated reservoirs affected by the Fukushima accident, Cs-137 activities in sediment-pore water were significantly higher than in reservoir water, with K-d values decreasing with depth and showing a negative correlation with NH4+ concentration. This indicates a continuous supply of bioavailable Cs-137 from the surrounding catchment area, making reservoir sediments a long-term important source of Cs-137 in riverine systems.

Summary: This study investigates the molecular transformations of Macondo Well Oil under photoinduced pathways using negative-ion electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry. The results show that photochemical oxidation occurs within the first hour and the composition of photoproducts remains similar after 24 hours of irradiation. Additionally, the toxicity of water-soluble photoproducts rapidly increases at early irradiation time points.

Summary: The dissolved N species, TOC, and TN in sediment cores of an eutrophic estuary were analyzed to understand the N geochemical variation in the sediment cores. The concentrations of ammonium and dissolved organic nitrogen (DON) were found to be extremely high in the pore water of the upper estuary. The mineralization of DON and TN provided the ammonium source to the sediment cores, and this process varied with depth.

Summary: There is a lack of knowledge regarding the long-term mobility of Pu-239 and Cs-137 in natural environments. Monitoring the distribution and migration of trace radioisotopes has the potential to provide insight into the underlying mechanisms of geochemical cycles. This study investigated the distribution of Pu-239 and Cs-137 in contaminated sediments and found that they primarily remained in the upper layers with limited migration.

Summary: This study reports the occurrence and spatial distribution of seven halogenated methanesulfonic acids (HMSAs) in water and sediment samples from Hangzhou Bay, China. Tri-fluoromethanesulfonic acid (TFMSA) was found to be the main contributor to the concentrations of HMSAs in water and sediment samples. The levels of HMSAs in water showed a seasonal pattern affected by temperature, precipitation, and river flow variations, while the levels in sediment were highest near the industrial area and river confluences. The concentrations of TFMSA were significantly positively correlated with total organic carbon (TOC) in water samples.

Summary: Barium (Ba) isotopes can serve as a tracer for riverine freshwater input to the ocean and marine biogeochemical cycling. This study investigates the processes affecting Ba cycling in Kiel Bight, a fjord in the Baltic Sea. The results show that Ba concentrations and isotope ratios vary with depth and are influenced by mixing of freshwater and seawater, as well as biological processes and sediment-water interactions. These findings have implications for understanding nutrient dynamics and the isotopic balance of Ba in the ocean.

Summary: Cytostatic drugs are commonly found in wastewater effluents due to their poor biodegradability, but the Fe(III)-EDDS complex has shown to efficiently degrade cyclophosphamide and 5-fluorouracil under solar light. The addition of EDDS widens the operational pH range of the solar photo-Fenton process, and a suitable Fe(III):EDDS ratio and initial dissolved oxygen level impact the degradation performance. Rapid degradation of the drugs was achieved within 1.5 minutes in the solar photo-Fenton process, with potential for total mineralization under relatively low Fe(III) concentration and H2O2 dosage.

Summary: Due to rapid socioeconomic development, the increasing attention is being given to antibiotic and heavy metal pollution. This study assessed the hazards associated with antibiotics and heavy metals in the surface water of the Yitong River in Changchun. The results showed varying concentrations of antibiotics and heavy metals based on seasonal and spatial distribution. Ecological risk assessment and human health risk assessment models revealed the presence of high-risk levels of antibiotics and heavy metals, with children being more vulnerable to the health risks.

Summary: This study investigated the dynamics of dissolved organic matter (DOM) in sediment cores of China's Lake Taihu, showing different vertical profiles of DOM and benthic fluxes of dissolved organic carbon (DOC) in algae accumulated, dredged, and central areas. The results indicated significant influences of terrestrial inputs and biological activities on DOM components in pore water, with different benthic fluxes observed in the three areas.

Summary: This study analyzed the geochemical characteristics of sediment cores and pore water in the Beikang Basin of the southern South China Sea. The results showed extremely low δ13C(DIC) in the pore water, a decrease in sulfate content with depth, kink-type depth profiles of enrichment factors for Sr, Ba, and Ni, and the presence of reducing sedimentary environment indicated by Mo, U, and REE features. The study concluded that fluid fluxes and tectonic settings greatly influence the properties and activities of cold seeps, leading to regional differences.

Summary: The study assessed the concentration of PCDDs/PCDFs and ecotoxicity in pore water of two reservoirs in Poland, comparing with DOC and TOC content. Higher dioxin concentration was found in pore water from Ro(z) over dotnow Reservoir than Rybnik Reservoir, with higher toxic responses recorded for A. fischeri than D. magna. The study indicates complex relationships between PCDD/F, ecotoxicity, DOC, and TOC in pore water, confirming the importance of these parameters in water environmental contamination.

Summary: The study aimed to investigate the interaction between organic matter fractions and polycyclic aromatic hydrocarbons (PAHs) in bottom sediments, using mussels as passive biomonitors and sediment quality guidelines for ecological risk assessment. The results showed that the concentration of PAHs in bottom sediments was influenced by the stable carbon form Cnh, with a significant positive correlation between the PAH concentrations in mussel tissues and sediments. Principal component analysis (PCA) suggested that fine fractions can increase the bioavailability of PAHs and play an important role in their distribution in sediments.

Summary: The quality of bottom sediments plays a crucial role in the functions of dam reservoirs. This study assesses the risk of metal contamination in sediments by combining different pollution indices. Zinc (Zn), lead (Pb), and cadmium (Cd) were found to dominate sediment contamination. Ecological risk assessment revealed high risks for all three metals, while human health risks were high for Pb and Cd. Sediments from the Rybnik reservoir posed a high potential ecological risk for Copper (Cu). The use of sequential BCR extraction and ecotoxicity analyses provided a comprehensive risk assessment of metal contamination in dam reservoir sediments.
