Potential enhanced N-nitrosodimethylamine (NDMA) formation under water treatment conditions
This study investigates two aspects of NDMA formation reactions: (i) evaluation of the potential effect of formaldehyde on NDMA formation, particularly in reactions of dimethylamine (DMA) and nitrite, and (ii) assessment of potential NDMA formation from a range of polymeric coagulants and flocculants upon exposure to disinfection oxidants. The results show that the presence of formaldehyde can ...
متن کاملN-Nitrosodimethylamine (NDMA) as a Drinking Water Contaminant: A Review
N-Nitrosodimethylamine (NDMA) is a member of a family of extremely potent carcinogens, the N-nitrosamines. Until recently, concerns about NDMA mainly focused on the presence of NDMA in food, consumer products, and polluted air. However, current concern focuses on NDMA as a drinking water contaminant resulting from reactions occurring during chlorination or via direct industrial contamination. B...
متن کاملAerobic biodegradation of N-nitrosodimethylamine (NDMA) by axenic bacterial strains.
The water contaminant N-nitrosodimethylamine (NDMA) is a probable human carcinogen whose appearance in the environment is related to the release of rocket fuel and to chlorine-based disinfection of water and wastewater. Although this compound has been shown to be biodegradable, there is minimal information about the organisms capable of this degradation, and little is understood of the mechanis...
متن کاملLeaching risk of N-nitrosodimethylamine (NDMA) in soil receiving reclaimed wastewater.
N-nitrosodimethylamine (NDMA) is a potential carcinogen frequently found in treated wastewater as a byproduct of chlorination. The potential for NDMA to contaminate the groundwater is a significant concern. A solute fate and transport model, Hydrus-1D, was used to evaluate the leaching potential of NDMA under different irrigation practices and soil properties. The results indicate that the risk...
