This project will develop analytical methods to study the speciation of inorganic and organic chloramines. This will enable laboratory-based studies of the impact of chloramine speciation on the formation of N-DBPs. The formation mechanisms and pathways of N-DBPs from their precursors (e.g. amino acids) will also be investigated. In addition, a study on the occurrence of organic chloramines and N-DBPs in drinking water will be undertaken, providing some of the first data for organic chloramines occurrence in drinking waters worldwide. The data from the occurrence study will also be used for a risk assessment study, with the support of currently available toxicity information on organic chloramines and N-DBPs.
