APPLICABILITY: The working range is 0.05 to 1.5 mg/m 3 for a 15-L air sample.

INTERFERENCES: Other pesticides such as aldrin, parathion, dieldrin, DDT and its metabolites, and polychlorinated biphenyls elute in the retention time band for chlorinated camphene.

OTHER METHODS: This is Method S67 [2] in a revised format. Toxaphene in air has been collected on Chromosorb 102 with acceptable recovery [3].
