Summary: The environmental conditions of groundwater and surface water vary greatly depending on the location, which can affect the physical and chemical properties of nanocomposites and pollutants used in remediation. In this study, magnetic nanocomposite microparticle (MNM) gels were used as sorbents for remediating PCB 126 as a model organic contaminant. The effects of ionic strength, water hardness, and pH on the sorption efficiency of the MNMs for PCB 126 were studied. The results showed that ionic strength and water hardness had minimal effects on the sorption of PCB 126 by MNM gels, while an increased pH resulted in a decrease in binding, likely due to anion-pi interactions.

Summary: This study analyzed the concentrations of persistent organic pollutants (POPs) in Franciscana dolphins from three regions in Brazil. The results showed that PCBs and DDTs were the predominant pollutants, with the highest PCB concentrations observed in highly urbanized and industrial areas. The sex and maturity of the dolphins had significant effects on the POPs concentrations. Although the concentrations of POPs are declining, PCB levels remain high and pose adverse health effects on the dolphins.

Summary: Recent studies have shown that unintentionally produced PCBs are major contributors to atmospheric PCBs and are controlling PCB burdens in agricultural soils across China. The dominant contributors to PCBs in Chinese agricultural soils are the legacy of historically produced and used commercial PCB mixtures, especially high-chlorinated congeners. Unintentional sources, such as pigment/paint, combustion-related sources, and polymer sealants, account for a significant portion of total PCBs in Chinese soils.

Summary: Traditional Monte Carlo simulation and age-stratified Monte Carlo simulation yielded average risks 2.6 times higher and standard deviations 3.7 times higher than actual values. In contrast, predicted risks of concentration-adjusted and correlated-parameter-adjusted models showed good agreement with actual ILCR values. Accurate simulation of exposure concentration and adjustment of correlated parameters can greatly improve MCS performance.

Summary: This study aims to identify the prevalence and potential influencing factors of impaired lung function in elementary school children in Wuhan, China. The results showed that children from rural areas had a higher prevalence of impaired lung function compared to those from urban areas. Several factors, including home renovations, physical exercise duration, preterm birth, and air pollution exposure during commuting, were associated with an increased risk of impaired lung function. Breastfeeding, longer window opening times, higher socioeconomics, and an urban living environment were found to be protective factors. It is recommended to promote breastfeeding, lengthen window opening times, and control household renovations and air pollution exposure to reduce the risk of impaired lung function in children in Wuhan.

Summary: High-throughput toxicogenomics is crucial in toxicity assessment of environmental chemicals, however, the limited data poses challenges to dose-response analyses. This study evaluates the effectiveness of informative priors in genomic dose-response modeling and benchmark dose estimation. Informative priors derived from historical data are sensitive to the specific datasets used for elicitation. Results suggest that BMD estimation with time-specific informative priors improves accuracy, decreases uncertainty, and enhances correlation compared to noninformative priors.

Summary: The BMD methodology is widely used for determining the toxicity value of chemicals, but its application to epidemiological data is limited. This study compares two different methods for BMD analysis in prospective cohort studies on bladder and lung cancer linked to inorganic arsenic exposure, and suggests that modeling adjusted RR values as continuous data for BMD estimation is a more generalizable approach harmonized with the BMD approach using toxicological data.
