Preliminary evidence of the occurrence of DDE as well as DDT in human fat made it necessary to study the Schechter-Haller method critically as applied to fat containing DDT and the degradation product, DDE. Through empirical standardization it was possible to make differential determinations of DDT and DDE totaling 5 micrograms in unknown fat samples, with rough estimations down to 2 micrograms. A modified Davidow column was used in a rapid method for isolating DDT and DDE. Among 50 samples all but 2 contained substantial quantities of DDE. The total DDT plus DDE ranged from 0 to 80 p.p.m., with DDE representing from 39 to 86% of the total. Chromatographic and spectrophotometric data provided evidence that the degradation product is DDE.
