Abstract
A personal sampling and analytical method for ethylene glycol aerosol and vapor in air was developed and tested. The personal sampler contains a glass fiber filter followed by two sections of silica gel. Samples are analyzed by gas chromatography. Ethylene glycol vapor at concentrations ranging from 4.2 to 327 mg/m3 for 3-L air samples can be measured. Ethylene glycol can evaporate from the filter during air sampling at 25 °C and enter the silica gel tube.
