Lead poisoning in Maryland
Lead poisoning remains a serious problem in Baltimore
Mapping blood lead levels in Maryland
In Baltimore, lead (Pb) poisoning affects thousands of children. Lead exposure is a public health crisis in Baltimore city.
As part of our policy work, we wondered how the blood lead levels (BLL) in children in specific Baltimore neighborhoods compared to the levels of children in Montgomery and Prince George’s counties. From information provided to us by Maryland Department of the Environment (MDE), we developed detailed maps of blood lead levels in children 0-72 months by census tracts (below) and found shocking disparities between blood lead levels in Baltimore city and the two counties.
