In 19 of the 20 families, concentrations of PBDEs were typically three times as high in children as in their mothers, said Sonya Lunder, the study's author. One child had six times the level of the chemical that was detected in her mother.

Lunder said young children are exposed to more of these substances because they play by putting their hands and other household items in their mouths after touching furniture or appliances that contain PBDEs. They also eat more and drink more, proportionally, than their mothers do, and food and drink can contain these chemicals, she said.
PBDEs, or polybrominated diphenyl ethers, are hormone-disrupting pollutants that build up in the blood and tissues. Two forms of PBDEs are no longer made in the United States but are still present in items in U.S. homes, the study said.

The study cited peer-reviewed tests that showed a single dose of PBDEs given to mice on a single day when their brains were growing rapidly can cause permanent behavior changes, including hyperactivity.
