Description:
In this paper, preliminary results of the application of an equilibrium method for determining the Henry's Law Constants (HLCs) for all the individual chlorobiphenyl compounds in the Aroclor mixtures are reported. Most of the individual compounds in Aroclor 1242 and 1254 have HLCs in the range of 2 to .0007 a+m/cu m/mol. A method is also described which permits the fugacity of the PCBs in natural waters to be determined. Preliminary results of this method with Lake Michigan water indicates that about 60% of the PCBs in the water samples tested were in true solution.
