Acute postnatal exposure to the pentaBDE commercial mixture DE-71 at 5 or 15 mg/kg/day does not produce learning or attention deficits in rats.

Polybrominated diphenyl ethers (PBDEs), flame retardant chemicals added to polymer products, have become ubiquitous in the environment, and they are bioaccumulating in humans and wildlife. Therefore, understanding their biological effects is important for public health. We have previously observed learning deficits in rats exposed to DE-71, a commercial PBDE mixture consisting primarily of pentabrominated diphenyl ethers, at a dose of 30 mg/kg/day from postnatal day (PND) 6 to 12.
