Summary: <br>This paper investigates the bioaccumulation and biomagnification potential of volatile methylsiloxanes (VMSs) in food webs. Due to limited published information, the toxicological effects of VMSs on aquatic biota and human ecology are not well understood. The results show conflicting findings regarding the bioaccumulation of VMSs in food webs, with some studies suggesting bioaccumulation and biomagnification potential, while others suggesting trophic dilution.

Summary: This study assessed the concentration, bioconcentration, and bioaccumulation of ten trace elements in juvenile fishes in the Lower Parana River. The results showed that all studied species bioaccumulate certain elements and that feeding habits determine trace element concentrations, with significant differences observed between trophic guilds. Further studies are necessary to understand differential behavior between different species within the aquatic web, particularly in the crucial nursery area of the Parana floodplain.

Summary: This study investigated the trophodynamics, bio-accumulation, and cancer risks of polycyclic aromatic hydrocarbons (PAHs) in 16 species collected from Laizhou Bay, China. Results showed that naphthalene was the most abundant PAH in marine organisms. The concentrations of PAHs varied among algae, benthonic animals, and fish, with combustion and oil spill being the primary sources. Algae and benthonic animals had a high ability to accumulate different rings of PAHs. A biodilution pattern of PAHs was observed in the marine food web. Some benthos and fish had carcinogenic risks above the safe limit, posing a threat to human health.

Summary: Cyclic volatile methyl siloxanes (cVMS) are extensively used and widely present in various environmental matrices, raising concerns about their environmental contamination and potential health hazards. This study comprehensively reviews their occurrence and environmental behavior in air, water, soil, sediments, sludge, dusts, biogas, biosolids, and biota. Higher concentrations of cVMS were found in indoor air and biosolids, but not in water, soil, and sediments except for wastewaters. No threat to aquatic organisms was identified, and mammalian toxicity hazards were not evident except for rare cases of uterine tumors under long-term exposures in laboratory conditions. More careful examinations are needed to establish strong evidence and inform policy-making regarding the production and use of cVMS to mitigate potential environmental consequences.

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.
