The results of the Morton Grove Lead Study suggest that airborne lead from autos using heavily traveled roadways may contribute to the blood lead levels of children, especially to that of preschool children. Because of these findings, it is recommended that baffles, such as trees, be utilized along major roadways passing through populated areas. Children residing along such roadways should receive instruction in hygiene so they understand the importance and reason for keeping non-food items out of their mouths and for frequent and thorough handwashing.
