The gas chromatographic determination of cyclodiene insecticides and their conversion products is often rendered difficult by the presence of PCB residues in environmental samples. This problem can be satisfactorily overcome by inducing photoisomerization reactions (λ > 290 nm) of some cyclodiene insecticides, thus producing the corresponding photoisomers in high yields. The photoisomers have longer retention times than their parent compounds and can therefore be identified and quantitatively determined by gas chromatography. The method can be improved by a subsequent UV irradiation of the samples with wavelengths above 230 nm in methanol. This procedure yields photodechlorinated products of the PCBs with shorter retention times but leaves the photoisomerization products of cyclodiene insecticides unaffected.
