Abstract
An air sampling and analytical method has been developed and validated for the personal monitoring of methyl carbamate. Methyl carbamate vapor is collected on silica gel tubes, desorbed from the tubes with water and analyzed by gas chromatography. An average vapor collection efficiency of 96.3% was obtained at concentrations ranging from 0.3-6.0 mg/m3. There was no loss in collection efficiency at a relative humidity of 84%.
