Plasma phthalate and bisphenol A (BPA) levels were determined in autistic children.
Oxidant/antioxidant status was also evaluated.
Plasma BPA levels of children with PDD-NOS were significantly higher than control.
BPA exposure might be associated with PDD-NOS and oxidative stress.
Intracellular oxidant/antioxidant imbalance might facilitate its neurotoxicity.
