Mirex is an organochlorine chemical with pesticidal and other industrial usages. Biologically, mirex was used as an insecticide for the control of imported fire ants in large areas of the southeastern U.S. Evidence of mirex survey exposure in a national survey of chemicals in adipose tissue led to a more intensive survey of the general population in treated counties of the southeastern U.S. A total of 624 adipose tissue specimens were collected from 40 sites selected randomly from 8 southeastern states where mirex was used widescale to combat fire ants. Tissue specimens were analyzed for mirex and selected other organochlorine compounds by electron-capture gas chromatography with confirmation by combined gas chromatography/mass spectrometry. Weighted statistical analysis of the data was conducted to estimate the level of mirex in the study area. It was estimated that 10.2% of the population of southern U.S. had quantifiable levels of mirex in adipose tissue. The estimated geometric mean of the quantifiable residue amounts was 0.286 ppm (lipid basis).
