NEW YORK (NBC) - A flame retardant linked to learning problems in children have quickly decreased in the blood of pregnant women in California after it was banned in that state ten years ago.
The chemicals called PBDE’s have long been used in foam furniture and can enter the body through household dust and food.
After research showed that even low levels of exposure during pregnancy affected a child's IQ, attention, and learning ability, California banned PBDE’s in 2004.
Now, a new study reveals blood levels in pregnant women at a San Francisco hospital fell by two-thirds since they were last tested three years ago.
Experts credit the ban on PBDE's for the drop which they say happened much more quickly than expected.
