| dc.description |
Nine amino acids (AAs) were examined under different oxidation conditions to determine their formation potential for regulated carbonaceous DBPs (trihalomethanes (THMs) and haloacetic acids (HAAs)) and selected emerging nitrogenous DBPs (haloacetonitriles (HANs), halonitromethanes (HNMs) and nitrosamines). Aspartic acid and histidine exhibited very high dihalogenated-HANs and HAAs formation during chlorination, but their reactivity significantly decreased after ozonation. Glycine followed by lysine yieled the highest level of HNMs and THMs formation during ozonation-chlorination, but they did not have measurable yields for either classes of DBPs during chlorination. All other AAs showed very low carbonaceous and nitrogenous DBP yields. The nitrosamine yields of all nine AAs were very low or below the minimum reporting levels during chloramination, ozonation, and ozonation-chloramination. These results indicated that the presence of AAs in natural waters can result in some contributions to certain halogenated DBPs depending on the oxidation conditions. However, they do not appear to be an important contributor to nitrosamines formation. |
