Abstract

A gas chromatographic-mass spectrometric (GC-MS) method for the determination of chlordane in air was developed. Chlordane collected in a Tenax-TA tube was thermally desorbed into a fused-silica capillary column and determined by GC-MS with selected ion monitoring. The relative standard deviation of the peak area obtained in recovery tests ranged from 1.1 to 5.1 % and the limit of detection was 5 pg (signal-to-noise ratio = 4). This method was applied to determine chlordane in indoor and ambient air samples in Kitakyushu, Japan.
