More than half of the 2011 models of children's car seats contain at least one hazardous chemical.
According to research by Ecology Center, 60 percent of more than 150 car seats tested included flame retardants, arsenic, lead and other heavy metals.
Despite that discovery, researchers found levels of toxicity have improved since they first started testing toxicity levels in 2008.
The group did not test to determine whether any chemicals were coming out of the car seat and exposing children.
