Summary: This study examines the interaction between trophic ecology and mercury contamination in the fish communities of two lakes in a pollution-impacted subarctic watercourse. The findings suggest that the complexity of the food web and the composition of species play a role in the transfer of mercury in fish. Piscivorous fish were found to have higher mercury concentrations, with some species exceeding health authorization limits, potentially impacting fishing and human consumption.

Summary: Microplastics have been found in aquatic ecosystems worldwide, and understanding their bioaccumulation and biomagnification is crucial for ecological risk assessment. However, variations in study methodologies have made it difficult to reach definitive conclusions. By compiling and analyzing available data, it is revealed that microplastics are more abundant in sediments compared to water, mussels, and fish. There is a significant correlation between mussels and sediments, but not between water and mussels or water/sediment and fish. Further research is needed to fully comprehend the biomagnification of microplastics in aquatic environments.

Summary: Studies have shown that microplastics ingestion by wild freshwater fish increases with urbanization, although a direct correlation with surrounding water microplastics concentration has not been identified. Microplastics were found in all published articles, with more than 50% of specimens analyzed in one study showing microplastics presence. Additionally, microplastics were found in the gills of fish, and there is evidence that they can translocate to different tissues of the organism.

Summary: Changing ecological conditions along environmental gradients influence patterns of biodiversity and ecosystem functioning. Aquatic food webs along stream gradients were studied to understand how networks of interacting species respond to these changes. The study found that while increasing ecosystem size, productivity, and species richness influenced trophic diversity, there was a nonlinear relationship between trophic diversity and the gradient. Trophic redundancy within the fish community decreased downstream along the gradient, but this relationship varied with fish species richness. Overall, this study highlights the importance of understanding the mechanisms that shape food web properties along gradients and their implications for ecosystem function in the face of environmental change.

Summary: This study investigated the variability of concentrations and distributions of PCB and PBDE congeners in 26 species from different locations around Scotland. The study found clear differences in congener distribution between sample categories and species, influenced by physiological processes and eco-biological parameters. Trophic magnification was observed for the ICES-7 PCBs and BDE47 using the traditional method, with CB52 showing the highest degree of magnification. The unbalanced dataset influenced the calculated trophic magnification factor (TMF) and sometimes the overall conclusions of congener biomagnification. The use of a balanced method is recommended for accurate TMF calculations, particularly in regional comparisons with difficult sampling requirements.

Summary: Knowledge on bioaccumulation and trophic transfer in food webs is crucial in evaluating contaminant hazards. This study investigated the presence of PFAAs in organisms sampled from Qinzhou Bay in the South China Sea, and found different distribution patterns between short-chain and long-chain PFAAs based on trophic positions. Results suggest a potential biomagnification effect of PFOS, while the effects of PFOA were less clear. Banned long-chain PFAAs were found to still persist in the coastal marine ecosystem, while emerging short-chain PFAAs showed high concentrations but no biomagnification.

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: 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.
