Title: Influence of structure and solution conditions on the halogenation rates and trihalomethane yield of parabens in chlorinated and brominated waters.
Abbrev. Abstract: Parabens are ubiquitous environmental contaminants that have been detected in surface waters due to widespread use as preservatives in personal care products. Organic contaminants may undergo halogenation reactions during drinking water treatment to form disinfection byproducts (DBPs). The effects of pre-halogenation and solution conditions on paraben reactivity towards free chlorine and bromine were investigated. The yield and speciation of regulated trihalomethanes (THMs) from bromo-paraben mixtures were quantified; parallel experiments were performed with NaBr and salicylates. THM bromine incorporation from brominated precursors was commensurate with equimolar additions of NaBr, indicating efficient displacement of aromatic Br⁺ by free chlorine. The results herein demonstrate new evidence of contributions from aromatic bromine towards polybrominated DBPs, which are of greater toxicity than their chlorinated analogues.
