- •
NH2Cl supplied the nitrogen during N-DBP formation from non-nitrogenous precursors.
- •
HAcAm yields from chloramination of LMWOAs were higher than those of HANs.
- •
Yields of THMs, HAAs and HAcAms were highest from chloramination of citric acid.
- •
DON concentration unlikely to be a good predictor of N-DBPs in chloramination.
- •
The rank orders for normalized BIFs were di-HAcAms > mono-HAcAms > tri-HAcAms.
