A new study involving Simon Fraser University researchers has found that prenatal exposure to flame retardants can be significantly linked to lower IQs and greater hyperactivity in five-year old children

Prenatal exposure to flame retardants can be significantly linked to lower IQs and greater hyperactivity in five-year old children. The researchers found that a 10-fold increase in PBDE concentrations in early pregnancy, when the fetal brain is developing, was associated with a 4.5 IQ decrement, which is comparable with the impact of environmental lead exposure. PBDEs have been widely used as flame retardants in furniture, carpet padding, car seats and other consumer products over the past three decades.

PBDEs have been widely used as flame retardants in furniture, carpet padding, car seats and other consumer products over the past three decades. While most items containing PBDEs were removed voluntarily from the market a decade ago, some are still in commerce and others persist in the environment and human bodies. Nearly all homes and offices still contain some PBDEs.

"The results from this and other observational human studies support efforts to reduce Penta-BDE exposures, especially for pregnant women and young children," says Lanphear. "Unfortunately, brominated flame retardants are persistent and North Americans are likely exposed to higher PBDE levels than people from other parts of the world. Because of this it is likely to take decades for the PBDE levels in our population to be reduced to current European or Asian levels."
