Summary: This study evaluated the degradation of fipronil under typical chlorination conditions, identified its disinfection by-products, and assessed the toxicity of unreacted and chlorinated solutions. The results showed that chlorination quickly degraded fipronil and produced toxic disinfection by-products, with potential mutagenic and developmental toxicant properties.

Summary: A database of 6310 disinfection by-products (DBPs) reported between 1974 and 2022 was constructed, providing a tool for screening new DBPs, comprehensive review, and predictive model development. The study presented the origin of the collected DBPs and conducted comparative analysis on their basic information. Most DBPs remained to be identified, with acids as the main functional groups, aliphatic and aromatic compounds as the major carbon frameworks, and molecular weights ranging from 200 to 400 Da.

Summary: With the increasing occurrences of algal blooms worldwide, the release of algal toxins threatens drinking water resources. Oxidation/disinfection processes have shown promise in removing algal toxins, however, the transformation of these toxins does not guarantee a reduction in toxicity. The formation of toxic transformation products (TPs) should also be considered, especially during chlorination. Further research is necessary to optimize oxidation/disinfection processes for effective reduction of toxicity.

Summary: This study investigates the challenge of providing safe tap water while limiting the occurrence of disinfection by-products (DBPs) in a full-scale drinking water treatment plant. Different technologies, such as aeration, coagulation, hydrogen peroxide dosage, ion exchange, and ultrafiltration, were studied in a real surface water matrix. The results show that agitation aeration is most effective in removing DBPs directly, while ion exchange resin is the best at inhibiting their formation. Hydrogen peroxide dosage also shows promising results in preventing the formation of bromate. This study serves as a reference for selecting optimal treatment technologies in full-scale drinking water treatment plants to limit DBP occurrence.

Summary: Chlorination is a commonly used technique for drinking water disinfection, but it can produce disinfection by-products (DBPs) that threaten water safety. This study introduces environmental microfluidics to a UVA-LED photocatalytic oxidation system for the rapid oxidation of organic matter. The results show that low pH conditions favor the adsorption and degradation of organic matter. The microreactor effectively reduces DBP formation potential and increases water purification efficiency.

Summary: Disinfection by-products (DBPs) are common organic contaminants in tap water and have raised wide concern due to their toxic, cytotoxic, and carcinogenic properties. Traditional quenching agents like ascorbic acid and sodium thiosulfate can cause varying degrees of DBPs degradation, while emerging quenchers like NAC and GSH show promise as ideal chlorine quenchers for organic DBPs. Sodium sulfite has been proven to be the ideal quencher for inorganic DBPs. This comprehensive review provides insights into the effects of traditional and emerging chlorine quenchers on different types of DBPs.

Summary: The fate of saccharin in the advanced ozone treatment and subsequent chlorination disinfection of drinking water was investigated. The results showed that ozone effectively degraded saccharin but converted it into disinfection by-product precursor. Subsequent chlorination produced disinfection by-products including trichloromethane, dichloroacetic acid, trichloroacetic acid, and dichloroacetonitrile, with their formation influenced by pH and the presence of anions.

Summary: This study evaluated the impact of exposure to poly-styrene nanoparticles (PS NPs) on the behavior, brain antioxidant activity, and DNA damage in male Swiss mice. It was found that mice exposed to PS NPs exhibited anxiolytic-like behavior and altered defensive response when confronted with a predator. Additionally, the exposure to PS NPs led to reduced brain antioxidant activity and increased DNA damage. These findings highlight the potential impact of PS NPs on mammals and underscore the ecotoxicological risks associated with their dispersion in natural environments.

Summary: In this study, the degradation of Dicamba methyl ester (DME) using a low-cost chlorine/ferrous process was investigated. Optimal conditions for DME degradation were determined using an artificial neural network (ANN) model and particle swarm optimization (PSO) algorithm, yielding a predicted yield of 88%. GC/MS analysis identified benzene, 1,2,4-trichloro-3-methoxy DME-BP as the only chlorine-containing byproduct. Total organic carbon (TOC) removal was analyzed using a Fenton-like process under optimized conditions, and toxicity assessments using Chlorella vulgaris microalgae indicated low toxicity of 20% when DME mineralization reached 62.52%.

Summary: The COVID-19 pandemic has caused unprecedented negative impacts. The potential effects of SARS-CoV-2 and microplastics in the aquatic environment are not well known. This study evaluated the ecotoxicological effects of exposure to SARS-CoV-2 and polyethylene microplastics in male adult Poecilia reticulata. The results showed behavioral changes, nephrotoxic and hepatotoxic effects, imbalances in ion homeostasis, and anticholinesterase effects induced by SARS-CoV-2 exposure. Polyethylene microplastic exposure caused genotoxic effects and increased enzyme activity. The combined exposure did not show synergistic effects. The study highlights the need for attention to the impacts of COVID-19 on aquatic biota.
