This test method covers the sampling and analysis of indoor atmospheres for residues of chlordane and heptachlor.
Formerly under the jurisdiction of Committee D22 on Air Quality, this test method was withdrawn in September 2011 since the use of the termiticides chlordane and heptachlor was discontinued over 30 years ago and residues of these chemicals in and around a household are expected to be undetectable.
1.1 This test method covers the sampling and analysis of indoor atmospheres for residues of chlordane and heptachlor.
1.2 This test method is based upon the collection of chlordane and heptachlor from air onto polyurethane foam (PUF) and analysis by gas chromatography coupled with electron capture detection.
1.3 This test method is applicable to concentrations of chlordane varying from 0.1 to 100 g/m3 and heptachlor varying from 0.01 to 80.0 g/m3 with sampling periods to collect at least 0.25 m3 of air. Detection limits will depend upon the conditions of the gas chromatography (GC) and the length of the sampling period.
