A method for the single step conversion of DDT, DDE, DDD (TDE), and DDT derived compounds to dibutyl phthalate (DBP) is described. The DBP can then by analyzed by GLC to determine the total content of neutral DDT metabolites. The method takes advantage of the facile ion pair extraction of permanganate ion from water to low polar solvents observed on addition of lipophilic ions such as tetrabutyl-ammonium ion. The two-phase reagent also contains sodium periodate and sodium hydroxide. Anisole is used as a high boiling solvent. The recovery of DBP from DDT, DDE, and DDD at levels corresponding to 0. 2, 2. 0, and 20 g DDE, respectively, was quantitative. The less reactive o,p'-DDT required a modified addition of reagents for quantitative recovery of o,p'-DBP. This procedure will also serve to simplify the determination of PCB compounds by eliminating interfering peaks.
