Ecology Center, a nonprofit environmental group, studied 150 2011-model car seats in three categories: infant, convertible and booster. The research found that six-out-of-10 contain at least one toxic chemical -- and some contain several.
So, which seats did the study say were the biggest offenders and which were deemed least toxic? Keep clicking to find out.
In the convertible car seat category, this Graco MyRide 65 Streamer and the same model in "Chandler" were deemed least toxic by the Ecology Center study. Also named "least toxic" in the the convertible class: Graco Comfort Sport in Caleo, Safety 1st OnSide Air in Clearwater, and Graco Nautilus Elite 3-in-1 in Gabe.
Ecology Center named the Graco Snugride 35 in Edgemont Red/Black and Graco SnugRide 30 in Asprey (seen here), one of the most toxic infant seats because, the group says, it contains harmful chemicals, such as lead, chlorine and bromine.
The Symphony 65 Car Seat in Liberty is considered a medium pick by HealthyStuff.org in the convertible seat category. The ranking is based on the amount of lead and bromine found in a study conducted by Ecology Center, a nonprofit group.
The Graco Nautilus Elite 3-in-1 in Gabe, seen here, is named one of the least toxic by Ecology Center. Seats named "least toxic" in the same convertible seat category include the Graco Comfort Sport in Caleo, Graco MyRide 65 in Chandler and Streamer and Safety 1st OnSide Air in Clearwater.
