Constant efforts have been devoted to exploring new disinfection byproducts in drinking water causally related adverse health outcomes. In this study, five halogenated nucleobases were identified as emerging water, including 5-chlorouracil, 6-chlorouracil, 2-chloroadenine, 6-chloroguanine, and 5-bromouracil. We developed a solid phase extraction-ultraperformance liquid chromatography-tandem mass spectrometry method with the limits of detection (LOD) recoveries ranging between 0.04-0.86 ng/L 54-93%, respectively. The frequency ranged from 73 100% maximum concentration up 65.3 representative samples. cytotoxicity Chinese hamster ovary (CHO-K1) cells varied great disparity, which 2-chloroadenine (IC50 = 9.4 μM) is appropriately three times higher than DBP 2,6-dichloro-1,4-benzoquinone 42.4 μM), indicating significant toxicological risk nucleobase-DBPs. To best our knowledge, study reports analytical method, occurrence, toxicity nucleobase-DBPs for first time. These findings will provide theoretical basis further research on probing relationship its mutagenicity human risk.

World's population is growing rapidly and it will touch 10 million by the end of 2050. Availability clean safe water for all a global challenge. Disinfection most important step in treatment to ensure inactivation pathogens from water. There are many techniques/materials available disinfection However, there also challenges associated with successful implementation methods including cost, type pathogens, other health implications caused due formation byproducts during process. In this chapter, background techniques as well recent trends area has been discussed detail an objective suggest safer strategies disinfection. by-products often lead their long-lasting toxic behavior. factors pH, residence period, temperature, natural organic matter, characteristics that significantly affect efficiency disinfectants fate by-products. Some carcinogenic, reproductive toxicants mutagenic nature. advancements can be avoided treatment. These have chapter along knowledge gaps provide basic outlook future research development alternatives.
