TLDR
For a given oxidant dose, the selective oxidants were more efficient than hydroxyl radicals for transforming ERMs-containing micropollutants, while hydroxy radicals are capable of transforming micropolutants even without ERMs.About:

Formation, precursors, control, and occurrence of nitrosamines in drinking water: a review.
TL;DR: This review summarizes major findings over the last decade related to nitrosamines in drinking water, with a particular focus on N-nitrosodimethylamine (NDMA), because it is among the most widely detected nitrosamine in drinking waters.

TL;DR: A DOC-normalized ozone dose, together with the rate constants for the reaction of the selected micropollutants with ozone and (•)OH, and the measurement of the ( •)OH exposure are proposed as key parameters for the prediction of the elimination efficiency of micropolutants during ozonation of municipal wastewater effluents with varying water quality.
