Soil fumigants, like 1,3-dichIoropropene and metham-sodium (forming methyl isothiocyanate) diffuse into the atmosphere, thus presenting a hazard to people in the surroundings. A method is described in which a large volume (50 PI) of extractant, used to desorb the compounds from charcoal, is injected
## Abstract A gas chromatographic analysis for vinyl acetate is presented. Vinyl acetate was sampled by adsorbing on activated carbon. It was desorbed with carbon disulfide with a mean efficiency of 83.0%. The analytical column was packed with 10% free fatty acid phase on acidβwashed ChromosorbβP.
