Elimination pattern of aroclor 1254 components in the bobwhite

The gas-liquid chromatographic profile for Aroclor 1254 did not maintain its integrity in bobwhite quail fed Aroclor 1254 for 14 days and clean food 14 or 42 days thereafter. Absorption of all components occurred at essentially the same rate, as shown by analysis of quail sacrificed within an hour after a single oral dose of Aroclor. Acentonitrile-hexane partitioning altered the peak pattern of the Aroclor 1254 standard.

Significant alteration of certain polychlorinated biphenyl isomers appeared to take place. Dechlorination was clearly apparent, and isomeric transformation is suggested.
