Despite dramatic reductions in population lead exposure over the past 2 decades, nearly 900,000 US children younger than 6 years still have elevated blood lead levels ( 0.483 µmol/L [10 µg/dL]).1-2 The problem disproportionately affects low-income children living in older dwellings. Available data suggest that subtle health effects, such as lower IQ scores in children, may extend to blood lead levels well below the 0.483-µmol/L (10-µg/dL) threshold.3 While not as well studied, an association between blood lead levels in this range and cognitive function of middle-aged and elderly men has also been reported.4 Further research may continue to redefine what constitutes an entirely "safe" level.
Much of the reduction in lead exposure to date has come from eliminating uses of lead, such as in gasoline, soldered cans, and housepaint, that were causing widespread, ongoing exposures.5 The opportunity for such relatively simple but powerful interventions . . . [Full Text of this Article]
