We developed a selective method for determining N,N-dimethyldodecylamine (DMDA) and N,N-dimethyloctadecylamine (DMOA) concentrations in river and sea water samples using liquid chromatography/tandem mass spectrometry (LC/MS/MS). DMDA and DMOA are suspected to be toxic, and DMDA is categorized as a "Class
