Abstract
- N-Nitrosodimethylamine (DMN) levels in ambient air were determined for an area surrounding an industrial site in Baltimore, MD. Using a Tenax GC cartridge for concentrating DMN and glass capillary gas-liquid chromatography/mass spectrometry with specific ion (m/e 74) monitoring, DMN was quantified. The limit of detection was ca. 0.3 ppt at 25°C. On the industrial site DMN levels reached 32,000 ng/m3 (10.67 ppb) of ambient air.
