Formation of novel disinfection by-products chlorinated benzoquinone, phenyl benzoquinones and polycyclic aromatic hydrocarbons during chlorination treatment on UV filter 2,4-dihydroxybenzophenone in swimming pool water.
Journal of Hazardous Materials(2019)
摘要
•BP-1 was removed quickly and genotoxicity increased during chlorination process.•19 products were tentatively identified in BP-1 chlorination, 11 were first reported.•Benzoquinones, phenylbenzoquinones, polycyclic aromatic hydrocarbons raised toxicity.•Toxic products formed via CC coupling, Baeyer-Villiger oxidation and hydrolysis.•BP-1 and chlorinated products were found in real swimming pool water samples.
