Dissolved organic matter (DOM) is the primary precursor of disinfection products (DBPs) during chlorination. However, compositional characteristics DOM transformation chlorination process in different source waters and its relationship to cytotoxicity remain understudied. Here, we used high-resolution mass spectrometry evaluate chlorination-induced molecular-level changes derived from surface water sources. We correlated components with profiles selected DBPs using new alternative methods predictive toxicological assessments. Our findings indicate a selective natural tendency for lignin protein conversion manual process. The reactivity bioactive compounds decreased order > tannin or ConAC. mainly attributed lignin- protein-like within CHO CHNO groups. Additionally, mitochondrial damage highly sensitive indicator DOM-induced cytotoxicity. toxicity revealed 37 common toxicity-driving characterized by low mass, medium H/C ratio, O/C reduction state, hydrophobicity. highlight need exploit health effects provide substantial experimental evidence necessity remove potential toxicants.

Growing concerns over public health and environmental safety have intensified the focus on minimizing harmful disinfection byproducts (DBPs) in water treatment. Traditional methods like chlorination, while effective against pathogens, often lead to formation of DBPs, which pose significant risks. This paper explores alternative strategies reducing DBP ensuring disinfection. The methodology involved a bibliographic study conducted through Scopus platform, using appropriate keywords. initial search yielded 9576 articles from period 2020 2024. key approaches identified include advanced oxidation processes (AOPs) such as UV/H2O2 ozone, mineralize natural organic matter (NOM) minimize chemical use sludge production; membrane-based filtration systems, reverse osmosis, effectively removing contaminants without disinfectants, Furthermore, conventional processes, coagulation filtration, serve crucial pretreatment steps lower NOM levels before Additionally, optimizing chlorine dosing, non-chlorine employing post-disinfection adsorption biological further mitigate formation. Finally, integration artificial intelligence process optimization is emerging promising tool for enhancing treatment efficiency safety. research contributes development safer, more sustainable solutions, addressing regulatory demands objectives.

It has been demonstrated previously that cupric oxide (CuO) can enhance the formation of one- to two-carbon-atom disinfection byproducts (DBPs) during water chlorination. Effects CuO on Chinese hamster ovary cell cytotoxicity chlorinated and underlying mechanisms were investigated in this study. Results showed 0.1 g L–1 elevated waters by 20% 120% at initial bromide concentrations 15 415 μg L–1, respectively. Increasing dose increased induced both known unknown DBP fractions, a more pronounced elevation was observed for former one. Unknown fractions accounting >70% characterized Fourier transform ion cyclotron resonance mass spectrometry. The presence decreased average molecular weight (416.4 vs 412.3 Da) assigned ∼2350 formulas after chlorination but number bromine-containing (165 328). contribution bromine addition/substitution pathways alteration identified almost doubled absence CuO. preferential brominated DBPs ascribed higher rate constant CuO–HOBr than CuO–HOCl complex lower adsorption energies based density functional theory calculations. This work provides insights into DBP-associated its mitigation strategies copper-containing distribution systems.
