Description
Summary:The levels of halocarbons have been determined in rural air in central Michigan using a sampling procedure employing pre-concentration on a porous polymer. The samples were analyzed by gas chromatography (GC) with an electron capture detector. Both qualitative and quantitative confirmation of the results were achieved by GC-mass spectrometry. Trichlorofluoromethane, chloroform, 1,1,1-trichloroethane, carbon tetrachloride, trichloroethylene and perchloroethylene were determined in the range of 30–130 parts per trillion. These concentrations agree well with data obtained by others in Washington state and Ireland indicating even distribution of the halocarbons in these latitudes.
