Summary: Environmentally persistent free radicals (EPFRs) are hazardous substances that exist stably in the atmosphere and are closely related to lung cancer. This study assessed the inhalation risk for EPFRs in PM2.5 and investigated the factors influencing this risk. The findings showed a strong correlation between EPFR concentrations and conventional pollutants, and identified temperature and wind speed as major factors influencing EPFR concentration in the atmosphere.

Summary: This study investigated the distribution of EPFRs in different soil particles and their contribution to OP. The results showed that the highest concentration of EPFRs was found in soil particles with diameters <0.15 mm. The DTT assay revealed that the redox activity of contaminated soil particles was 4 to 8 times higher than that of un-contaminated samples, and it was strongly associated with EPFRs, ROS, and PAHs.

Summary: PFRs generated during thermal treatment of contaminated soils may lead to the formation of toxic compounds, with limited understanding of their formation and toxicity in soils contaminated by PAHs. Results show that toxic compounds peak at 300 degrees Celsius during thermal treatment, with algal toxicity mainly due to the generation of O-2(center dot-), center dot OH, and H2O2.

Summary: This work systematically investigated the interactions between hematite with different facets and various NPAHs under visible light. The results showed that hematite nanocube (HNC) exhibited a higher degradation rate for NPAHs due to its greater number of electron accepting sites and reactive oxygen species (ROS). Furthermore, the degradation pathways of different NPAHs were found to be significantly different. The findings of this study provide theoretical guidance for the removal of NPAHs and the application of hematite photocatalysts in environmental remediation.

Summary: This study compared the adverse effects among anthracene (ANT), anthraquinone (ANQ), and environmentally persistent free radicals (EPFRs) induced by ANT transformation on clay surfaces in earthworms. The results showed that EPFRs-exposed earthworms experienced more severe histopathological damage, dysbiosis of reactive oxygen species, and oxidative damages compared to ANT and ANQ exposure. High-throughput sequencing analysis further revealed that EPFRs induced significant changes in the composition and structure of earthworm gut microbiota, potentially aggravating EPFRs toxicity. These findings highlight the importance of assessing the potential risks associated with EPFRs in PAHs-contaminated soils.

Summary: A long-lived, soluble heptacene and a persistent tetrabenzononacene were synthesized through sixfold TIPS-ethynylation combined with fourfold bromination and pi-extension via Stille coupling. The stability of both compounds was enhanced by double TIPS-ethynylation on every other benzene ring. The ambipolar transistor material tetrabromoheptacene showed good performance, with a n-channel mobility of up to 0.036 cm(2)V-1s-1, as confirmed by the generation of its monoanion and monocation.

Summary: Piezoelectric catalytic technology is widely used in contaminant removal and has become a hot research topic for potential practical applications. In this study, the piezoelectric performance of piezo-materials was precisely regulated by changing their morphology. SrBi2Ta2O9 (SBTO) with different morphologies were successfully synthesized via different methods, and the SBTO synthesized by hydrothermal method (SBTO-HR) exhibited the most excellent catalytic activity. The enhanced piezoelectric catalytic performance of SBTO-HR is attributed to its nanoflower morphology, which allows for easier deformation and polarization under external force, leading to a stronger piezoelectric potential for accelerating the separation of electrons and holes.

Summary: Efficient treatment of the emerging organic pollutant CBZ is a challenge due to its persistence, toxicity, and bioaccumulation. Piezocatalysis, a method that utilizes mechanical energy, has shown promise in degrading organic pollutants. In this study, a novel piezo material CBB was synthesized and exhibited excellent degradation activity for CBZ, with a removal efficiency 4.13 times higher than that of BTO. The superior performance of CBB can be attributed to its easily polarized structure and strong internal alternating piezoelectric field.

Summary: Research has found that biodegradable plastics are more prone to generating harmful microplastics in a short amount of time. The oxidation process of the plastics significantly affects their micromechanical properties, further exacerbating the formation of microplastics. The increased presence of oxygen-containing functional groups leads to higher adhesion and roughness of the plastic, indicating that the environmental risks of biodegradable plastics should not be ignored.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
