Octanol-water partition coefficients of 58 poly-chlorinated biphenyl (PCB) congeners have been determined by reverse-phase C/sub 18/ high-performance liquid chromatography (HPLC) of Aroclor 1242 and 1254 mixtures. High-resolution glass capillary gas-liquid chromatography was used for the detection of the eluted individual congeners. Some PCB congeners behaved atypically from other organics on reverse-phase HPLC, and empirically derived correction factors were used to adjust K/sub ow/ values. Congener log K/sub ow/ values for PCB's ranged from an average of 4.5 for N/sub Cl/ = 1 to 8.1 for N/sub Cl/ = 7. The environmental implications of PCB K/sub ow/ values and congener behavior on the C /sub 18/ reverse-phase column are discussed. 35 references.
