Abstract
The gaschromatographic determination of Toxaphene in the presence of other chlorinated hydrocarbons with similar retention times is often difficult. The practibility of a new method, based on photodehalogenation of the interfering substances, is shown during the analytical determination of Toxaphene residues in selected environmental samples, especially in fish and fish products. Irradiation of the extracts after clean-up procedures with wavelengths at 254 nm lead directly to photodechlorination products of interfering substances with shorter retention times and makes it possible to determine the Toxaphene components quantitatively, which are mostly stable under the same experimental conditions.
