Children like to look out open windows. While at the windows, their hands and fingers are picking up lead dust or tiny lead chips. These same hands then go into their mouths.
Some children even chew on the sill or pick at the paint.
This lead-base paint enters their body. Many children love to play in window sills with their toy cars and action figures. The car wheels and toy figures help grind lead chips into dust which the child can either breathe or swallow. To find the hazards, open each window and look at the sides and upper part of the window. Check area between the interior window and screen.
