“…Solid-phase extraction (SPE) is a commonly used technique for pre-concentration of trace compounds in water via adsorption on selective cartridges (Camel, 2003a;Loos and Barceló, 2001). It is extensively used for the detection of multiple trace compounds due to its high operability and repeatability, low MDLs, and low solvent consumption (Wang et al, 2016;Kubáň et al, 2015). More importantly, the availability of diverse sorbent materials with modified surface functionalities significantly improves the selectivity for target analytes (Hennion, 1999;Hu et al, M A N U S C R I P T 2018).…”

“…Disinfection byproducts (DBPs) are compounds unintentionally produced from the reactions of natural organic matter with disinfectants during water disinfection (Richardson and Kimura, 2016;Wang et al, 2016). Over 700 DBPs have been detected in drinking water; of those, trihalomethanes (THM) and haloacetic acid (HAA) have been strictly regulated due to awareness of their high health risks in humans (Saleem et al, 2019).…”

2,6-dichlorobenzoquinone (2,6-DCBQ) is an emerging disinfection byproduct frequently detected in drinking water. Previous studies have indicated that 2,6-DCBQ causes oxidative stress damage in some live systems, but this has yet to be tested in vivo in mammals. In the present study, adult mice were exposed to 2,6-DCBQ for 30 d via gavage at 0 ~ 100 mg kg− 1 with the responses of antioxidant enzymes (superoxide dismutase [SOD] and catalase [CAT]), key oxidative stress response genes (Heme oxygenase-1 [HO-1], NADPH quinone oxidoreductase 1 [NQO1] and glutamate-L-cysteine ligase catalytic subunit [GCLC]) in the Nrf2-keap1 pathway, and lipid peroxidation (malonaldehyde, MDA) as an indicator of oxidative damage being measured. Our results indicated that 2,6-DCBQ decreased the activities of SOD and CAT, repressed transcription of key genes in the Nrf2-keap1 pathway, and caused measurable oxidative damage. These results reveal the impact of 2,6-DCBQ in a model mammalian system and are key to understanding the potential impacts of 2,6-DCBQ in humans.

“…In the first part of this work, the degradation of CAA by H 2 O 2 alone (to confirm the production of hydroxyl radicals by inter) and in the presence of ferrous iron Fe 2+ catalyst was investigated. In fact, CAA was detected among others as stable halo-benzoquinone disinfection by-products in treated water (Wang et al 2014(Wang et al , 2016. It has been detected in pulp mill bleaching effluents and polychlorophenols industrial wastewaters (Treviño-Quintanilla et al 2011;Martínez-Huitle et al 2004;Zhu et al 2010)…”

In this work, the degradation of chloranilic acid (CAA) by chemical oxidation with H2O2 alone and in the presence of ferrous iron Fe2+ catalyst was investigated in order to improve our understanding on the novel metal-independent approach. The interesting and efficient metal-independent hydroxyl radicals (OH) production by using halogenated quinones and H2O2 has been currently demonstrated. The results clearly confirmed the formation of OH radicals from the reaction of CAA with H2O2. CAA was slowly decayed by chemical oxidation with H2O2 and followed a pseudo-first kinetics. H2O2 doses ≥ 1000 mM were required to achieve complete CAA decay from 1 mM CAA. However, low total organic carbon (TOC) removal was measured with the accumulation of carboxylic acids. The addition of Fe2+ enhanced the kinetics of CAA degradation and reduced the required dose of H2O2. High TOC removal was obtained, almost complete release of chloride ions, without accumulation of carboxylic acids. The decolorization of methylene blue (MB) aqueous solutions was performed using H2O2, H2O2/CAA, H2O2/Fe2+, and H2O2/CAA/Fe2+. H2O2/CAA/Fe2+ was the most effective method in decolorizing MB solutions due to the accelerated Fe2+ regeneration. Coupling Fenton reagent with CAA seems to be promising alternative to physical activation in water and soil treatment.
