Summary: Monitoring the disinfection process and swimming pool water quality is crucial for preventing microbial infections and associated diseases. Disinfection by-products (DBPs), including carcinogenic and chronic-toxic compounds, can form from reactions between disinfectants and organic/inorganic matter. This study investigated the water quality trends of THMs, HAAs, HANs, and HNMs in two swimming pools over 48 weeks. The results showed that AOX concentrations can be used as an important parameter to estimate DBP concentrations in chlorinated pool waters.

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 aimed to investigate the degradation kinetic modeling and mechanism of Cl-HNMs under monochloramine activated by ultraviolet of 254 nm (UV/NH2Cl) treatment. The results showed that UV was the dominant factor in the degradation of Cl-HNMs, followed by HO•, reactive chlorine species (RCS), and CO3•-. The study also proposed possible degradation pathways for Cl-HNMs under UV/NH2Cl treatment.

Summary: In this study, the degradation of 2,4,6-Trichloroanisole (2,4,6-TCA) by UV/chlorination with different UV sources was compared. It was found that UV-LED (275 nm)/chlorination achieved the highest removal rate of 2,4,6-TCA, reaching 80.0%, and the degradation was mainly caused by direct UV photolysis and indirect hydroxyl radical oxidation. Factors such as initial chlorine dosage, 2,4,6-TCA concentration, and pH value significantly affected the degradation process. The presence of natural organic matter and bicarbonate inhibited 2,4,6-TCA degradation, while chloride ion had negligible effects. UV-LED (275 nm)/chlorination also showed promising results in removing 2,4,6-TCA in real water, indicating its potential in controlling 2,4,6-TCA pollution and odor problems.

Summary: This study elaborates the comprehensive environmental transformation of short-chain chlorinated paraffins (SCCPs) in a rice seedling exposure system. The selected congener of SCCPs, CP-4, was quickly absorbed, translocated, and phytovolatilized by seedlings. The transformation of CP-4 was mainly attributed to degradation by rhizosphere microorganisms, root exudates, and abiotic factors, with a majority being phytotransformed by rice seedlings. A total of 61 transformation products were identified through complex pathways.

Summary: Marine plastic pollution poses a potential hazard to global ecosystems and human health, with micro-fibers derived from synthetic textiles contributing significantly to plastic debris. This study investigates the degradation behavior of poly(lactide acid)/poly(hydroxybutyrate) (PLA/PHB) fabrics in marine seawater, specifically in the presence of UV light and dissolved oxygen. The results show that the degradation rate of PLA/PHB fabrics is accelerated under these conditions, leading to a continuous mass loss and a significant decrease in tensile strength.

Summary: This study systematically investigated the transformation kinetics and pathways of Sulfamonomethoxine (SMM) by UV/H2O2 in swine wastewater. The degradation of SMM in real wastewater was found to be lower than in synthetic wastewater due to the presence of conventional contaminants. Different factors, such as H2O2 dosage, pH conditions, and the presence of carbonate and nitrate, were found to influence the degradation of SMM in the UV/H2O2 system.

Summary: This study presents a method for the simultaneous determination of multiple pharmaceuticals in environmental water samples using ultra-high-performance liquid chromatography coupled with ultra-high-resolution time-of-flight mass spectrometry. The optimized separation method allowed for detection limits ranging from 2 to 7 ng L-1 and quantification limits between 7 and 23 ng L-1 for the targeted molecules within a three-minute run. The method was validated using samples collected from different surface waters and showed the highest concentrations of pharmaceuticals found in surface water in the Litani river, Lebanon.

Summary: Bromoform (CHBr3) is an important precursor of reactive bromine species in the troposphere and stratosphere. Previous models have only considered natural production of CHBr3 from marine organisms, but this study finds significantly higher levels of CHBr3 in water and air due to anthropogenic sources in an industrialized area. These findings suggest that industrial discharges may be an important missing factor in estimates of organic bromine flux to the atmosphere.

Summary: Studies indicate that industrial chlorination discharges are the main cause of TBP accumulation in seawater in the Gulf of Fos, France. The concentrations of TBP in European conger, purple sea urchin, and Mediterranean mussel were higher than published references. Industrial outflows were identified as hotspots for TBP in marine organisms. Although the threat to humans is limited, there is a high environmental risk in the industrial Gulf of Fos, but toxicological references are lacking.

Summary: Disinfecting swimming pool water is crucial for preventing waterborne diseases, although it can lead to the formation of disinfection by-products (DBPs), which can have harmful health effects. This study focuses on the reaction between chlorine and particles released by bathers in swimming pools. Filtered and unfiltered backwash waters from multiple swimming pools were collected and analyzed, and their reactions with varying concentrations of chlorine were examined. The results showed that a significant amount of DBPs, such as chloroform, haloacetic acids (HAAs), and haloacetonitriles (HANs), were generated during the chlorination process, with approximately 50% of them being derived from particles brought by bathers.

Summary: Photodegradation plays a key role in litter decomposition under climate change, as water scarcity hinders organic matter turnover. A study found that sunlight exposure affects the chemical characteristics of two typical Mediterranean tree species, Quercus ilex and Q. pubescens. Exposure in summer led to a decrease in lignin content through dearomatization and/or dephenolization, and also caused a reduction in alkyl content associated with cutin and waxes. Winter exposure with weaker irradiation resulted in a smaller decrease in lignin content. Overall, photodegradation can enhance litter transformation, depending on suitable climate conditions.

Summary: Managing organic agricultural wastes is a challenge in modern agriculture. The European Union encourages the discovery of cost-effective and environmentally friendly ways to utilize such wastes. Organic agricultural waste can be used as a culture medium for fungal strains, producing secondary metabolites like 6-PP with antifungal properties. This study aims to find the optimal formulation for 6-PP production using an experimental admixture design.
