Summary: The treatment of Erythrosine B using electrochemical advanced oxidation processes (EAOPs) like electro-Fenton, UVA photoelectro-Fenton, and solar photoelectro-Fenton was studied. Irradiation was found to be crucial in increasing hydroxyl radical production and in the recover of iron catalyst, leading to faster color and COD removal degradation under light application. The UVA photoelectro-Fenton process with a 100W lamp showed the best removal performance but high energy demand, while the solar photoelectro-Fenton system had the lowest and competitive energy demands with complete removal.

Summary: In today's industries, there is a need to degrade non-biodegradable compounds before their discharge into the environment. This study focused on the degradation of Orange II, a widely-used azo-dye. The photo-Fenton process was used to study the degradation under different conditions, and it was observed that homogeneous catalysis provided better results in primary degradation and mineralization compared to heterogeneous catalysis.

Summary: Various composite cathodes were prepared and characterized, with the finding that using polyurethane sponge in cathode-shaping can greatly enhance the hydrophobic property of the cathodes and lead to the preparation of super-hydrophobic carbon cathodes. These cathodes showed improved reduction of O2 to H2O2, making them ideal for electro-generation of H2O2 with high efficiency and stability in the degradation of cefepime.

Summary: This review discusses the application of various materials as catalyst supports, including activated carbon, biochar, and fibers. It introduces the advantages and optimum conditions of different catalysts. Alginate-based catalysts are easy to prepare and exhibit high degradation efficiency. Zeolite-based catalysts are structurally stable and perform well in successive cycles. Fiber-based supports have both catalytic and cathodic functions due to their flexibility and conductivity. Graphene and carbon nanotubes have highly stable and conductive properties, promoting electron transfer.

Summary: This study investigated the urinary concentrations of unmetabolized PAH compounds among workers and customers in waterpipe and cigarette cafes, and found significant differences between the exposed and control groups. The type of tobacco was found to be an influential factor for the urinary levels of PAHs. The study also revealed a positive and significant relationship between PAHs and oxidative stress biomarkers as well as kidney injury biomarkers. This suggests that workers in these smoking cafes are at risk of detrimental health impacts.

Summary: This study investigated the exposure risk of female beauticians to PAHs and found that their urine samples had high concentrations of pollutants. The concentrations of PAHs, 1-OHP, and TTMA in the urine samples of the exposure group were higher than those of the control group. Among the PAHs compounds, DahA, BaP, and IndP had the largest share. Additionally, kidney damage and oxidative stress biomarkers were positively correlated with urinary PAHs values. Therefore, female beauticians face high health risks in terms of kidney injury and DNA oxidative stress.

Summary: This study investigated the prevalence of waterpipe tobacco smoking (WTS) among Iranian adults and explored socioeconomic inequalities associated with this culturally-rooted smoking practice. The results showed a higher prevalence of WTS among younger adults, men, smokers, obese individuals, and those with higher socioeconomic status. Thus, targeted interventions are needed to reduce the prevalence of WTS among high-income communities.
