Abstract A method for the determination of termiticides present in ambient air was simplified by modifying the extraction thimbles used in the Hewlett-Packard supercritical fluid extractor so they could be used for collection as well as extraction of termiticides. The method was applied to the determination of chlorpyrifos and technical chlordane. The termiticides were trapped on cartridges containing Florisil and foam plugs, extracted with carbon dioxide in the supercritical fluid extractor, and determined by capillary gas chromatography with electron capture detection. On the basis of a 20 m3 sample, detection limits were 0.1 ng/m3 for chlorpyrifos and 1.0 ng/m3 for technical chlordane.
