Experts say a sharp rise in Autism rates in the United States may be due in part to an exposure of toxic chemicals.
Now they're calling for greater scrutiny of those chemicals that could potentially lead to the disorder.
Autism and environmental experts say lead, mercury and other neurotoxic chemicals have "a profound impact on the developing brain."
Autism is a neural developmental disorder that leads to impairments in behavior and communication.
About 1 in 110 children in the United States has it.
And it affects boys more than girls.
