A generator column technique has been used to directly determine log K/sub ow/ values for 15 PCB congeners and biphenyl. The method circumvents many of the experimental difficulties encountered with the traditional shake-flask system. Log K/sub ow/ values generated by this procedure are compared with data obtained from the shake-flask method, two chromatographic estimation techniques, and the computational method of Hansch and Leo. Log K/sub ow/ values reported for the higher chlorinated congeners, including octa- and decachlorobiphenyl, are some of the highest ever measured directly.
