They are massively carcinogenic on contact.  They have on 'no effect
level', i.e. concentrations in the body so small that they are hard to
detect (parts per billion) still seem to statisticly induce cancer.  On
the other hand, the "PCBs" being discussed are really PCB-laden oils,
not just pure PCBs.
