According to the article, "in certain regions of the country, including parts of New York, Pennsylvania and Ohio, more than 1 in 7 children tested for elevated levels of lead in their blood. Minnesota had the highest overall rate of young children with disturbing blood lead levels, at 10.3 percent. That was followed by Pennsylvania (7.8%), Kentucky (7.1%), Ohio (7%) and Connecticut (6.7%)."
Furthermore, because lead paint is typically found in pre-1978 homes and buildings, exposure appears to be more likely for children in poorer zip codes. This reiterates a study covered in our April blog post, "Lead Paint Violations Significantly Higher in Low Income Areas" and further illustrates that lead exposure, especially from lead paint, is still a major concern for public officials and families in older homes.
