Summary: This article presents the results of experiments on the effect of chlorine dioxide as an additional oxidant on swimming pool water quality. The experiments showed that chlorine dioxide effectively removes organic compounds and their chlorine derivatives, and supports water disinfection. However, discontinuation of chlorine dioxide leads to deterioration in microbiological water quality and secondary growth of microorganisms, as well as an increase in conductivity and concentration of inorganic compounds.

Summary: The chemical transformation of DHHB, a UV filter found in sunscreens and personal care products, in outdoor swimming pools was investigated. Free chlorine was the dominant factor contributing to the degradation of DHHB, while sunlight and reactive species had a smaller impact. The presence of certain substances inhibited or promoted DHHB degradation. The study highlights the significant health risks posed by DHHB and its chlorinated transformation by-products.

Summary: This study investigates the impacts of urea degradants on urea degradation and disinfection byproduct formation. It finds that while the combination of urea degradant and chlorine can effectively remove urea, it leads to a significant increase in the concentration of disinfection byproducts, particularly brominated DBPs. Therefore, the use of urea degradants together with chlorine should be carefully considered due to potential DBP-related health risks.

Summary: Population growth has led to industrialization and intensive agricultural methods, resulting in deterioration of water quality due to contamination by hazardous pesticides. The herbicide Diuron (DIU) has been studied as a priority pollutant. The BaO-MWCNT composite material was used to modify the working electrode surface, increasing the efficiency of the Faradaic reaction and enhancing the electrochemical surface area. The developed sensor showed good selectivity, sensitivity, and reliability for DIU determinations.

Summary: Bromate, a by-product of water disinfection, was found to have high concentrations in swimming pools. It was determined to be a non-threshold carcinogen based on its ability to induce DNA damage. Different age and activity groups showed varying exposure levels, with top athletes having the highest exposure and adults having the lowest exposure.

Summary: Per- and polyfluoroalkyl substances (PFAS), widely used chemicals in consumer products for their water and stain resistance properties, have been detected in various water sources around the world. However, their presence in swimming pool water, which could expose humans directly and act as a unique matrix for concentration through evaporation, has not been reported. This study analyzed water samples from different types of swimming pools in six Florida cities and found 14 PFAS, including six perfluoroalkyl acids, present in all samples. The highest PFAS levels were observed in city pool water in Miami, Melbourne, and Tampa. This study highlights the overlooked but significant exposure pathway of PFAS in communities.

Summary: A comprehensive study was conducted to investigate the efficient removal of human body fluids (HBFs) related pollutants from swimming pool water using UV irradiation combined with electrochemistry. The results showed that the EC/UV treatment exhibited the highest removal rates for these pollutants compared to other treatments. The EC/UV process was resilient to changes in water parameters and could lessen the generation of disinfection by-products. This green technology has the advantages of no chlorine-based chemical additive, easy operation, continuous disinfection efficiency, and fewer byproducts production.

Summary: This work successfully fabricated a nitrate potentiometric sensor by utilizing the stability, electrical conductivity, and versatility of graphite-based inks. The hydrophobicity of graphite was also exploited to design an ion-selective electrode, preventing the formation of a water layer. The use of printing technologies allowed for easy miniaturization and lower fabrication costs. The printed sensor, composed of a graphite working electrode and a Ag/AgCl reference electrode, showed excellent sensitivity, stability, and selectivity, making it a great alternative for environmental and industrial applications.

Summary: Due to the anticipated rise in demand for ammonia, there has been increased research on viable methods for its recovery, with a focus on reducing the high energy demand associated with traditional ammonia production. Bioelectrochemical systems (BESs) offer a promising alternative for ammonia recovery, with lower energy demand compared to other methods at the lab-scale. This paper explores the fundamentals and opportunities of bioelectrochemical ammonia recovery in various BES devices and discusses the challenges in scaling up for industrial adoption.
