“…(MacKeown et al, 2021) showed a linear correlation for low iodide concentrations (< 8 µg L -1 ), which was not observed anymore for higher iodide contents. For chlorination at typical chlorine doses of 1-3 mg L -1 , 20% of the iodide was incorporated in organic I-DBPs at pH < 8 in one study (Dillon et al, 2015). A similar trend of iodine and bromine incorporation has been observed in other studies, ranging from 10 to 40% of halogen bound to DOM (Criquet et al, 2015;Hua et al, 2006;Zhao et al, 2017).…”
