N-nitrosodidimethylamine (NDMA) ia a volatile N-nitrosamine (VNA) and a known carcinogen of animals and possibly of humans. Poisoning has been shown to cause severe liver damage and internal bleeding in humans leading to death.

NDMA is an emerging drinking water contaminant that is of interest to EPA and the environmental community. Its presence in drinking water is a potential health concern, because the EPA's IRIS data base lists the concentration of NDMA required to result in a one in one million lifetime cancer risk to be only 0.7 ng/L. NDMA is produced by industrial sources, such as the manufacture of rocket fuel, but has also been identified as a potential disinfection by-product. See the references for more detailed informaion.
