Templeton and Chen (2010) also foun

Templeton and Chen (2010) also found only very low and rare occurrence of N-nitrosodimethylamine and other
nitrosamines in UK drinking water, with the sole exception of N-nitrosodibutylamine, which was found in one distribution
system up to a maximum concentration of 6.4 ng/L. More recently, Wang et al. (2011) found N-nitrosodimethylamine, Nnitrosodiethylamine, N-nitrosomorpholine and N-nitrosodiphenylamine (0.4e20.5 ng/L) in water samples collected
from 12 DWTPs after chlorination and chloramination. The occurrence of AAs in drinking water has hardly been studied
compared to the wide number of reports on the occurrence and fate of NAms in DWTPs. On the contrary, there are several studies about the occurrence of aromatic amines, mainly 4- chloroaniline, in textile azo dye processing plant effluents (Pinheiro et al., 2004; Rehorek and Plum, 2007; Alves de Lima et al., 2007).
