  Naphthalene

Naphthalene was found in 5 of 10 umbilical cord blood samples from babies born in U.S. hospitals in 2004, at concentrations ranging from 85.9 to 198.5 ng/g (lipid weight, in whole blood). It was also found in 3 of 3 adult blood samples, at concentrations ranging from 17.8 to 39.5 ng/g (lipid weight, in whole blood).
