Summary: In response to the criticism by Huisman et al., this article demonstrates that their claims are based on incomplete evidence, misinterpretation of data, or do not actually refute our model. While our model, like any ecosystem models, has its simplifications and uncertainties, it outperforms existing approaches that ignore biology and cannot predict toxin concentration.

Summary: Compared to chlorine, purified chlorine dioxide can reduce the concentrations of chlorate and halogenated organic byproducts in produce under postharvest washing conditions. Chlorine dioxide exhibits lower disinfectant demand than chlorine, allowing for lower concentrations to be applied. This study demonstrates that purging ClO2 from the chlorine and ClO2 (-) mixture used for its generation can substantially reduce ClO3 (-) concentrations. Switching to purified ClO2 also reduces the concentrations of lipid-bound oleic acid chlorohydrins and protein-bound chlorotyrosines in produce.

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: This study investigates the differences in molecular dissolved organic matter (DOM) in upstream and downstream areas of Phong River, Thailand, as well as the effects of coagulation/sedimentation and disinfection on DOM composition. The results show that the most abundant class of DOM in the river is carbon, hydrogen, and oxygen-containing compounds (CHO features). Disinfection by chlorine (Cl2) and chlorine dioxide (ClO2) leads to the formation of chlorinated CHO compounds (CHOCl) and other disinfection byproducts (DBPs). The study also identifies unique DBPs formed in each disinfection process, indicating the presence of unique DBP precursors in different water samples.

Summary: This study reports the presence of six new aromatic nitrogenous disinfection byproducts (DBPs) in drinking water. Haloanilines completely degrade in the presence of chlorine within 1 hour, but about 20% remains in the presence of chloramine after 120 hours. Haloanilines show high stability in the absence of disinfectants at pH 5-9. Eight haloanilines were detected in chloraminated finished water and tap water, with the highest total concentration reaching 443 ng/L. The cytotoxicity of haloanilines was lower than that of regulated DBPs. The formation and control of haloanilines in drinking water call for further investigation.

Summary: Snow with large specific surface area and strong adsorption capacity can effectively adsorb atmospheric pollutants, leading to an increase in disinfection by-product (DBP) precursors in surface water. The dissolved organic matter (DOM) in meltwater is mainly composed of low molecular weight organics with low aromaticity and high unsaturation. DBP formation and cytotoxicity indexes in chlorinated meltwater are positively correlated with air quality index and are influenced by snowfall stages. The yield of halonitromethanes in meltwater is significantly higher than that in surface water.

Summary: In this study, it was discovered that the level of TOX in chlorinated waters had been significantly underestimated under common analytical conditions. The addition of quenching agent sodium thiosulfate resulted in a two-phase decomposition pattern of total organic chlorine and total organic bromine, indicating the important toxicological significance of the DBPs responsible for TOX decomposition. Nontarget analysis using high-resolution mass spectrometry revealed the molecular formulas for the decomposed TOX, and it was found that the level of unknown TOX in chlorinated waters was considerably higher than previously thought.

Summary: This article provides a comprehensive overview of the distribution, biological traits, risks, and control methods of Limnoperna fortunei. The planktonic larval stage is identified as a critical period for the expansion of this species, and its biofouling process relies on the adhesion of byssus to substrates. Various physical and chemical methods have been proposed and used to control Limnoperna fortunei, with sodium hypochlorite showing effectiveness in preventing adhesion. However, effective and environmental-friendly antifouling strategies are still lacking, particularly in drinking water treatment systems. This review not only enhances the understanding of Limnoperna fortunei but also provides guidance for prevention and control.

Summary: A novel perovskite-type catalyst was developed for emergency removal of harmful algae in water. The results showed that La2CuO4/PMS system achieved significant removal efficiency of Microcystis aeruginosa cells (97%) and chlorophyll-a (100%) within 20 minutes without significant release of dissolved organic carbon and metals in water. The generation of & BULL;OH, SO4 & BULL;-, 1O2, and & BULL;O2- was responsible for algae inactivation and subsequent algal organic matters removal. The proposed heterogeneous catalytic mechanism suggested that La portion in La2CuO4 destabilized the cells by increasing zeta potential of algae suspension, while Cu portion facilitated electron transfer to improve the yields of & BULL;OH and SO4 & BULL;-. This study demonstrates that the new catalytic PMS process promises viable and effective control of harmful algal bloom impacts in water treatment.
