Baltimore's longtime scourge of childhood lead poisoning continues to ease, but hundreds of young children each year still are being unwittingly exposed to a toxic metal that can cause lasting learning and behavioral problems.
That's the upshot of the latest report from the Maryland Department of the Environment. In 2008, 468 children in Baltimore city were found to have elevated levels of lead in their blood, down from 624 the year before. That drop continues a decline that dates back at least to 1999, when the city recorded 2,902 lead-poisoned children, according to the city's health department.
Just 2.5 percent of children tested in the city had elevated lead levels last year, the state reports, down from 3.5 percent in 2007.
That's good news, because even tiny amounts of lead in young children can cause neurological problems that can hamper learning and trigger aggressive behavior; larger doses can lead to mental retardation. Youngsters get poisoned mainly by ingesting lead dust from deteriorating paint -- a particular problem in Baltimore, with its older housing stock. Most of the 713 Maryland children found last year to have elevated lead levels lived in the city.
State law attempts to regulate children's lead exposure in rental housing, but 62 percent of the youngsters found to have problems live in owner-occupied homes, according to the state.
And while lead poisoning is less of a threat outside the city, there were upticks in the number of youngsters testing positive for lead in Carroll, Frederick, Harford, Howard, Kent, Montgomery, Prince George’s, St. Mary’s and Washington counties, noted the Coalition to End Childhood Lead Poisoning. Ruth Ann Norton, the advocacy group’s executive director, said that cities and counties alike must do more to deal with lead hazards in their housing stock, including owner-occupied homes.
