Light Congener % Contribution. Comparison of congener profiles for PCB 6-74 for the 20 referents exceeding the construction worker subject's median value for the sum of light congeners. These referents with the highest levels of light congeners have a very different profile of congeners compared to the construction workers, most notably for congeners 6, 8, 16, 26, 33, 37, and 41.
