Formation of NDMA by Chloramination of Nitrogenous Pharmaceuticals [PDF]

open access: yesWater Practice and Technology, 2010
Many disinfection by-products (DBPs) are formed during water chlorination, including trihalomethanes (THMs) and haloacetic acids (HAAs). Disinfection with chloramines is often used to reduce the production of regulated DBPs. However, chloramination can lead to the formation of N–nitrosamines, including N–nitrosodimethylamine (NDMA), a probable human ...
