  PCB-66

PCB-66 was found in 10 of 10 umbilical cord blood samples from babies born in U.S. hospitals in 2004, at concentrations ranging from 4.7 to 122.3 pg/g (lipid weight, in whole blood). It was also found in 3 of 3 adult blood samples, at concentrations ranging from 494.9 to 3,342.7 pg/g (lipid weight, in whole blood).

In polychlorinated biphenyl (PCB) family of chemicals - banned industrial insulators and lubricants; cause cancer and nervous system problems.
