The following is a list of results of our examination of a
number of AC1 samples for polychlorinated biphenyl (PCB)
contamination.

The analyses were made by an adaptation of our basic PCB
method. We were unable to determine if PCB's were present
in the three FMC samples because they contained substances
that interfered with our method of detection.
