Analysis of volatile N-nitroso compounds in drinking water at the part per trillion level

ConclusionVolatile gc-amenable N-nitroso compounds have not been found to be present in drinking water, even at ultra trace levels. Since sensitive analytical procedures do not currently exist for detecting the non-volatile N-nitroso compounds, such as the N-nitrosotriazines it should be clearly understood that these results refer only to the gas-chromatograph amenable N-nitroso compounds. Nothing is to be inferred as to the presence or absence of the more thermally labile N-nitroso compounds.

N-Nitroso Compounds in the Ambient Community Air of Baltimore, Maryland

Abstract N-nitroso compounds, primarily dimethylnitrosamine, have been found to be present as air pollutants in residential areas of Baltimore. The DMN levels were found to vary from 16 to 760 ng/m3.
