Formation of (halo)acetamides and (halo)acetonitriles from the reaction of monochloramine and (halo)acetaldehydes in water
… combined chlorine, such as haloacetonitriles and haloacetamides, might be more toxic than regulated DBPs. Monochloramine has been shown to react with aldehydes, common DBPs formed from ozone and free chlorine disinfection, to form carbinolamines that slowly dehydrate to imines which undergo fast …

Characterization of Unregulated Disinfection By-Products (DBPs) in Chloraminated Water and Estimation of Associated Health Risks
… capture detector (LLE/GC-ECD) method for haloacetamides (HAMs) was revised and validated. The method showed good accuracy and precision for 7 HAM species, but not for monochloroacetamide and monobromoacetamide. Together with haloacetamides, a total of 49 DBPs were measured in three batches …

Reduction of Disinfection Byproduct-associated Toxicity by Adjustment of Distribution System pH
… (N-DBPs) such as Haloacetonitriles (HANs) and haloacetamides (HAMs) have come under scrutiny in recent years due to their high toxicity compared to currently regulated carbonaceous disinfection byproducts (C-DBPs). Lowering concentrations of N-DBPs in drinking water is an important step for …

Study on the formation of nitrogenous disinfection by products from the reaction between dichloroacetaldehyde and monochloramine
… have shown that haloacetonitriles (HANs) and haloacetamides (HAMs), two unregulated N-DBP groups, were commonly found in drinking water with chloramine disinfection. Although these N-DBP groups occur at lower levels than chlorinated DBPs, they are shown to be more toxic and can significantly …

Wildfire Impacts on Water Quality and Implications for Disinfection Byproduct Formation
Forested watersheds are used worldwide as sources of high-quality drinking water. These areas have coevolved with wildfire, but climate change-induced increases in temperature and drought, plus mismanagement of forested areas are increasing the frequency and severity of wildfires. These can have …
