Abstract

Toxaphene is a complex technical mixture that has been found ubiquitously in the environment but has caused issues for analysis, especially of individual congeners. This paper reports the elution order of 25 major toxaphene congeners on three gas chromatographic (GC) columns. The three different stationary phases generally had similar elution orders for the toxaphene congeners, but fewer co-elutions occurred on a low bleed, low polarity column. These congeners are examined in air particulate matter SRMs, 1648a, 1649a, and 1649b as well as SRM 3067 Toxaphene in Methanol. SRM 3067 had mass fractions an order of a magnitude greater than the air particulate SRMs which ranged from 0.568 ng g-1 ± 0.018 ng g-1 dry mass (B9-2006 in SRM 1648a) to 12.9 ng g-1 ± 0.20 ng g-1 dry mass (B9-715 (P 58) in SRM 1649a. The three air particulate SRMs all had different mass fractions and proportions of congeners relative to total toxaphene. SRM 3067 may be useful as a natural mixture toxaphene congener calibrant. SRMs 1648a and 1649b will serve as reference materials for the analysis of 21 toxaphene congeners in atmospheric particulate samples.
