Abstract
A selective headspace-GC-MS-method for the determination of dithio-carbamat es- and thiuram disulfides-residues in vegetables after conversion into car bondisulfide with an aqueous solution of tin(II)chloride hydrochloric acid is described. The limit of quantitation is 0.02 mg CS2/kg. The recovery is in the 80-100% range. Using an internal standard, the repeatability (relati ve repeatability standard deviation) is 5%.
