As mentioned above, there is scarcely any information regarding the formation of NAms (mainly focused on the NAms regulated: N-nitrosodimethylamine, N-nitrosodiethylamine and N-nitrosomorpholine) and nothing published about AAs in drinking water treatment plants. Taking into account the toxicity of these amines, it seems of interest to study the behaviour of both kinds of compounds (AAs and NAms) together in the different treatment steps of a DWTP. From the foregoing, the objective of this study was to establish the occurrence and distribution profiles of both kinds of amines within a full scale drinking water treatment plant that employed chlorinated agents as a disinfectant. This is the first
study to evaluate the behaviour of 14 AAs during the disinfection treatment, which was implemented parallel to the
study on 10 NAms. In this way, the effectiveness of the different treatment steps could be established with regard to
either removing these compounds or, on the other hand, finding when these amines are formed during these steps. The
study was completed by evaluating the effect of seasonal variations in climate conditions (water temperature and rain)
on the occurrence of the amines throughout the DWTP.
