[Determination of aldrin, dieldrin and endrin in the air by gas chromatography]

A gas chromatographic method of determination of aldrin, dieldrin and endrin in air has been developed. The method involves trapping in ethylene glycol, extraction with hexane and determination by electron capture gas chromatography on a Gas Chrom Q column coated with 15% QF-1/10% DC-200. The determinability of the method amounts to 0,0015-0,003 mg/m3.
