Getting More of the Lead Out

Monday, March 9, 2009   

St. Paul - Children who have acceptable levels of lead in their blood can still suffer developmental effects, and
declining levels of lead poisoning in children should not make parents and government leaders complacent. That's the advice from the Minnesota Center for Environmental Advocacy (MCEA), which supports a bill that would lower the threshold of lead exposure required for actions such as follow-up medical evaluations.

MCEA public health scientist Samuel Yamin says studies link lead levels below the current cut-off of ten milligrams per deciliter of blood with problems that show up later in life.

"Significant losses of IQ points, other measurable indicators such as tests of academic aptitude and performance, neurologic and psychological development, have all been shown to be impacted by lead exposures within this range."

The legislation now being considered would cut the threshold in half, from ten to five milligrams of lead. Yamin says the MCEA foresees potential interim steps, such as advising and educating patients, if lead levels are under the current minimum for required action.

High environmental lead levels are mostly concentrated in poorer areas of major cities with large numbers of older houses. But Yamin says cases of lead poisoning show up in all parts of the state.

"We shouldn't become complacent and think that, just because you don't live in the very inner city of Minneapolis or St. Paul, then there's no way it could be an issue."

A study published this month in the journal Pediatrics shows a dramatic decrease in the number of children diagnosed with lead poisoning in the last 20 years.
