Lead poisoning estimate increases to 1 in 38 children

NEW YORK — More than half a million U.S. children are now thought to have lead poisoning, roughly twice the previous high estimate, health officials reported Thursday.

The increase is the result of the government last year lowering the threshold for lead poisoning, so more children are now considered at risk.

Too much lead can harm developing brains and lead to a lower IQ. Lead poisoning used to be a much larger concern in the United States, but has declined significantly as lead was removed from paint and gasoline and other sources.

The new number translates to about 1 in 38 children. That estimate suggests a need for more testing and preventive measures, some experts said.

Budget cuts last year eliminated federal grant funding for such programs. Those cuts represent "an abandonment of children," said David Rosner, a Columbia University public health historian.

"We've been acting like the problem was solved and this was a thing of the past," he added.

Most cases of lead poisoning are handled by tracking and removing the lead source, and monitoring the children to make sure lead levels stay down.
