A research report on toxic chemicals in children's car seats was released by the Ecology Center on Wednesday and found over half contained toxic chemicals.

Over 150, 2011 model car seats were tested for bromine, chlorine, lead, and other heavy metals and allergens.

While some seats were found to be virtually free of the most dangerous chemicals, over 60 percent contained at least one of the chemicals tested for.

The substances have been linked to allergies, birth defects, impaired learning, liver toxicity, and cancer in children.

The reports says that babies are the most vulnerable because their bodies are still developing and they spend a lot of time in their car seats.
