Summary: This study aimed to fill the knowledge gap between external exposure and effect dynamics by determining the impact of BPA on immune response and constructing a PBTK-TD model. The results showed a high induction of immunomarkers by BPA and different temporal dynamics. Therefore, a thorough characterization of biomarker response is important for further Environmental Biomonitoring.

Summary: Bisphenol A (BPA) is a concerning chemical due to its endocrine disrupting function, high production volume, and persistence in aquatic environment. A physiologically-based toxicokinetic (PBTK) model was modified to accurately simulate the fate of BPA in fish. The experiments showed that BPA metabolism in fish is not only limited to the liver, but plasma and gills may also play a role.

Summary: ndl-PCBs are persistent environmental pollutants that can accumulate in the tissues of animals and humans. Contaminated feed is the main route of human exposure, so predicting the transfer of ndl-PCBs from feed to animal products is crucial for human health risk assessment. A physiologically based toxicokinetic model was developed in this study to describe the transfer of various ndl-PCBs from contaminated feed into the liver and fat of fattening pigs.

Summary: Arsenic poses challenges in PBTK model development and risk analysis, with complex metabolism and sparse information on specific metabolites. PBTK models have been used for exposure and dose-response analysis for arsenic, particularly for multi-route exposures and multiple toxic effects. Refinements to arsenic PBTK models, such as improving methylation biotransformation parameters and estimating interindividual variability, can enhance confidence in risk assessments.

Summary: This article presents a study on the distribution and kinetics of a new class of pollutants, bisphenol Z, in zebrafish. By establishing a physiologically based toxicokinetic model, researchers were able to predict the concentrations of bisphenols in different organs of the zebrafish and found that these bisphenols mainly distribute to the carcass and gonads.

Summary: This study investigated the interactions of atrazine and chlorpyrifos mixtures on aquatic organisms using mechanistic mathematical models. The modeling focused on the inhibition of acetylcholinesterase by the chemicals, but synergistic effects could not be demonstrated in adult fish despite predictions from the model.

Summary: A physiologically based toxicokinetic model was developed to study the toxicokinetics of retrorsine in mice and rats. The model was validated to determine the hepatic toxicity of retrorsine and translate in vitro toxicity data to in vivo dose-response data. This study provides a flexible tool for the risk assessment of retrorsine.

Summary: The study investigated the migration of styrene monomers from polystyrene food contact materials into food simulants, finding that fat content and high temperatures significantly increased the level of styrene migration. The use of ANOVA statistical analysis and t-test analysis revealed key factors influencing the migration process.

Summary: This study reviews the generation and disposal of food processing byproducts (FPBs). The transformation of FPBs into microalgae cultivation can lead to high-value food ingredient production, while reducing costs and increasing productivity. Despite remaining challenges, the microalgal transformation of FPBs shows economic viability and environmental sustainability.

Summary: This case report discusses three dairy cows accidentally exposed to non-dioxin-like PCBs (ndl-PCBs) on a German farm. The cows had significant levels of PCBs in their milk and blood, mainly consisting of PCBs 138, 153, and 180. A physiologically based toxicokinetic model was developed to understand the fate of ndl-PCBs in the animals, including transfer to calves via milk and placenta. The model was also used for risk assessment by estimating kinetic parameters.

Summary: This study screened and characterized bacteria with excellent BPA-degrading abilities and found that B. subtilis P74 showed the highest BPA degradation performance. This strain exhibited stable degradation performance over a wide range of temperatures and pH levels, and it was also effective in degrading high concentrations of BPA.

Summary: Standardized laboratory tests with a limited number of model species play a crucial role in chemical risk assessments. A multispecies toxicokinetic model based on data from 69 freshwater fish species in Canada was developed to predict bioconcentration, showing promising results with some tendency of overestimating measured values. This bottom-up approach potentially provides more accurate predictions for chemical risk assessments.

Summary: This article discusses the health benefits and structure of arabinoxylan, a complex fiber found in grains like wheat, barley, and corn. The source and extraction process of arabinoxylan can affect its structure, and further investigation is needed to understand its pure ingredient's benefits on human health. The article also highlights the relationship between arabinoxylan's structure and its functionality in cereal products and emphasizes the importance of studying its health implications in arabinoxylan-rich products.
