Summary: This study investigated the levels of BTEX in Tehran from 2018 to 2020, using passive sampling and GC-FID method at five different monitoring stations. The total concentration of BTEX was estimated to be 65.39 μg/m³, with a higher average concentration in 2019-2020 compared to 2018-2019, mainly due to a significant increase in Toluene concentration during the pandemic era. Although Benzene levels have decreased in recent years, the annual average concentration at the five stations remained higher than the EU, India, Japan, and Iraq standards.

Summary: In order to fully understand the source characteristics and human health effects of atmospheric volatile organic compounds (VOCs), a 12-month measurement of VOCs was conducted in a coastal area in East China. The results showed that industrial areas had the highest concentrations of VOCs, with aromatics and halohydrocarbons being the most predominant groups. Industrial processes, organic solvents, dyeing, plastic synthesis, traffic emissions, and pesticides were identified as the major sources of VOCs in the region. The study also found that bromoform, hexachloro-1,3-butadiene, C1-C3 halogenated alkanes, and benzene homologs could be important indicators of industrial VOC emissions. Furthermore, the study revealed that halohydrocarbons contributed to ozone formation potential, while aromatics contributed to secondary organic aerosol potential in industrial areas. Health risk assessment indicated a high probability of non-carcinogenic risk in the region at 10 m height and 50 m radius, and minor carcinogenic risk at 70 m height and 1000 m radius. The compound 1,2-Dibromo-3-chloropropane was identified as the largest contributor to both non-carcinogenic risk and carcinogenic risk in the region.

Summary: Supercapacitors have attracted a lot of research interest recently. However, it is still challenging to create mixed transition metal oxide-based supercapacitor materials with large specific capacitance, structural strength, and high energy efficiency at a low cost. In this study, dysprosium-doped nickel manganese oxide with different concentrations was prepared using a simple co-precipitation method for energy conversion systems. The electrochemical performance of the Dy-doped NiMnO3 on Copper foam (CF) as the conductive substrate was investigated. The results showed that the 0.05 M Dy-doped NMO/CF electrode exhibited high specific capacitance and energy density, suggesting the potential of using large amounts of Dy-doped NiMnO3 as a material for next-generation supercapacitors.

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.

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.
