Summary: This study assessed the occupational dermal exposure assessment methods used in several TSCA risk evaluations and found that the current modeling approach may overestimate the total dermal absorbed doses for chlorinated chemical manufacturing and feedstock use scenarios. The best-practice recommendations support a tiered, integrated approach to dermal exposure assessment that emphasizes collecting qualitative data and using validated models aligned with current industrial practices. Collaboration among industry, EPA, and other stakeholders is encouraged to develop a standard approach to exposure assessment under TSCA.

Summary: This study compared the adsorption capacity of naturally aged, biofilm-covered microplastic fibers (BMFs) for perfluorooctane sulfonate (PFOS) and lead (Pb) at environmentally relevant concentrations. Results showed that aged MFs exhibited higher surface areas due to biomass accumulation and had higher concentrations of adsorbed Pb and PFOS, with variations among polymer types. The increased contaminant adsorption was linked with altered surface area and hydrophobic/hydrophilic characteristics of the samples.

Summary: Toxic chemicals have detrimental effects on the environment, climate, and human health, and their distribution is currently unfair across different regions. This study utilizes toxic release data in 2017 and extends the U.S. multi-regional input-output model to analyze the production and consumption-based accounting of toxic release by states and the inter-regional transfer of embodied toxic release. The findings demonstrate that the production-based toxic release is concentrated in central states and the Great Lakes Region, while consumption-based accounting shows more equal distribution across regions.

Summary: External force exerted on cyclobutanes can dramatically influence product selectivity through nonstatistical dynamic effects, as demonstrated by experiments and computational modeling. This effect critically depends on external force, reactant stereochemistry, and intermediate stability.

Summary: The first set of TSCA risk evaluations showed significant deviations from the recommendations of the National Academies, including narrow problem scopes, inadequate characterization of uncertainty, insufficient consideration of population variability, and lack of consideration for background exposures and cumulative risk. These deviations result in underestimation of population exposures and health risks.

Summary: This study aimed to evaluate the factors influencing listing decisions under the ESA by the U.S. Fish and Wildlife Service. Data from 143 ESA listing decisions were collected, and factors such as taxonomic group, ownership of habitat, aquatic or terrestrial habitat, and number of listed threats were found to be significantly correlated with listing decisions. The study highlights the importance of comprehensive data for informed listing decisions to help conserve threatened species.

Summary: Mentions of malnutrition, sarcopenia, frailty, and obesity were low in US state/territorial Older Americans Act program multi-year aging plans. Clearly defining and incorporating these conditions into measurable goals, strategies, and outcomes may improve support for healthy aging in the future.

Summary: This paper estimates the long-term effects of early childhood exposure to toxic chemicals, particularly airborne metals, on school-level standardized test performance. The study finds that higher levels of airborne toxicity, specifically chromium, during early childhood are associated with worse educational outcomes a decade later.

Summary: The electromagnetic field in an optical cavity can modify and control chemical reactions through vibrational strong coupling, requiring a quantum description. The use of quantum transition state theory helps to explain resonant effect, collective effect, and selectivity in cavity-catalyzed reactions. Perturbative analysis of polariton normal modes supports the theoretical calculations and provides a general approach for other VSC phenomena.

Summary: ROCOF is a key parameter to monitor in the presence of high renewable energy penetration. High ROCOF can lead to power plant shutdowns and interruptions to customers. Demand response (DR) is a cost-effective means to mitigate high ROCOF, and an ANN-based controller is proposed in this article to regulate frequency and mitigate high ROCOF under high intermittency of PV systems.

Summary: EPS production is a self-protection mechanism that helps microorganisms counteract adverse effects in unfavorable environments. The study found that protein content in EPS was the highest, and Cd(II) stress significantly increased EPS production in two strains of bacteria. The stress also led to the formation of specific chemical moieties. The addition of Cd(NO3)(2) effectively regulated EPS components, especially protein content, and improved adsorption capacity.

Summary: Government websites in US states play a crucial role in communicating information about PFAS to the public, with an emphasis on personal responsibility over corporate accountability. Discrepancies in the type and availability of information presented across states may hinder residents from being adequately and equally informed about PFAS contamination and associated health risks.

Summary: The controversy over glyphosate-based herbicides (GBHs) is rooted in methodological and normative factors, including differences in testing pure glyphosate and glyphosate formulations, the potential toxicity of adjuvant chemicals, and scientists' preconceptions and methodological choices. Lack of consensus on the science poses challenges for policymakers, highlighting the importance of considering the normative foundation underlying the toxicological science behind GBH assessments.
