Abstract
Abstract A method for the simultaneous determination of benzene and trace concentrations of 1,2-dibromoethane and 1,2-dichloroethane in ambient air was developed, with the use of gas chromatography-mass spectrometry and selected ion monitoring. Samples were collected at ambient temperature on a solid adsorbent followed by thermal desorption into the gas chromatograph-mass spectrometer. The chromatographic column was made of glass (2 m × 1.8 mm I.D.) and packed with 6% poly- m -phenyl ehter on Tenax GC (60–80 mesh). Four different adsorbents including porous polymers and a carbonaceous material were evaluated for the extraction efficiency of the compounds in air. Sampling periods can be extended from 10 min to several hours and the use of personal sampling equipment is feasible. Samples were taken at different locations in the Stockholm area including streets, parking garages, car repair shops, inside cars and in a private house with a garage on the ground floor.
