The percentage of 1- to 5-year-olds in the U.S. with blood lead levels at or above 10 mcg/dL has dropped from about 88% between 1976 and 1980 to 0.8% between 2007 and 2010, CDC researchers reported. They assessed data from the National Health and Nutrition Examination Survey and found disparities in blood lead levels among different racial and income groups. The findings appear in the Morbidity and Mortality Weekly Report.
