Summary: The study on the St. Lawrence River showed that BHTQ was the dominant contaminant in dissolved water, and sediment had higher sorption capacities for most target contaminants compared to SPM. Different contamination profiles were found in lake sturgeon and northern pike, indicating that the accumulation of UVAs and IAs in fish depends on their feeding behavior.

Summary: This study found that nanoplastics have an impact on fish in the aquatic environment. The accumulation of nanoplastics was observed in both the digestive and non-digestive organs of the tooth-carp fish, with higher concentrations in the gut, liver, and gill than in the skin and muscle. The presence of triclosan in the diet did not affect the uptake of nanoplastics by the fish, and both contaminants appeared to accumulate independently of each other.

Summary: Chemicals with elevated bioaccumulation profiles pose potential risks to public health and the environment. Existing methods for bioaccumulation determination are not suitable for ionizable organic compounds (IOCs). By using the zebrafish embryo model, researchers elucidated the toxicokinetics and bioconcentration of eight IOCs with diverse traits. The results provide an understanding of the partitioning behavior of IOCs and improve predictive bioconcentration modeling.

Summary: This study investigates the toxicokinetics and bioconcentration of ionizable organic compounds (IOCs) using zebrafish embryos as a model. The results show that these compounds are rapidly taken up and cleared in zebrafish, indicating their readily bioavailability in ionized forms. Predictive bioaccumulation models were constructed based on the human pharmacokinetic proportionality factor, apparent volume of distribution (V-D), and validated using hydrophobicity-based parameters. The study highlights the utility of biologically based ''read-across'' approaches for predicting bioaccumulative potential of IOCs.

Summary: The study investigated the bioaccumulation behavior of D6 in rainbow trout and found that the depuration of D6 in fish was mainly through biotransformation in the fish body, leading to a lack of biomagnification. The bioaccumulation capacity of D6 was markedly less than many hydrophobic organochlorines based on comparisons with similar profiles for other chemicals.

Summary: Methyl siloxanes, commonly used in consumer products, were found in road dust samples around a manufacturing site. The predominant siloxanes in the samples were D-3, D-4, D-5, and D-6, with relatively low concentrations. Daily intakes of total siloxanes via road dust ingestion were low, especially for adults. Further research on the risks and distribution of siloxanes released from manufacturing sites is needed to better understand potential impacts on human health.

The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

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.
