[Determining the levels of permethrin and kadethrin in the air by the method of gas chromatography].
A gas chromatographic method for determination of permethrin and kadethrin in air has been developed. The method involves trapping in ethylene glycol, extraction with benzene and determination by electron capture gas chromatography on a Gas Chrom Q column coated with 4% DC-L-SX-3-0295. The determinability of the method amounts to 0.006 mg/m3 (permethrin) and 0.16 mg/m3 (kadethrin).
