The CDC spent almost $2 million on six cities' lead prevention programs, but data is hard to obtain. However, we learned that in Pennsylvania 10 percent of children tested had levels of 5 or more micrograms per deciliter of lead in the blood.
The percentage of confirmed lead exposure cases in Pennsylvania has decreased by 47 percent in children under the age of 7 since 2007, but these 20 cities continue to remain incredibly vulnerable. The Pennsylvania Department of Health reported that the primary source for childhood lead poisoning in Pennsylvania is exposure to aging, deteriorating lead-based paint (chips and dust).
