PCB-137 was found in 9 of 10 umbilical cord blood samples from babies born in U.S. hospitals in 2004, at concentrations ranging from 18.4 to 132.5 pg/g (lipid weight, in whole blood). It was also found in 3 of 3 adult blood samples, at concentrations ranging from 1,170.9 to 3,946.7 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.
