In a July 12 hearing, federal researchers testified to the Senate Committee on Environment and Public Works about the latest scientific findings on the effects of lead on child development and public health. The hearing came as Congressional budget proposals for fiscal year 2013 are calling for funding cuts to Centers for Disease Control and Prevention (CDC) programs that address indoor lead hazards.
The CDC has stated that no safe blood lead level for children has been identified. In May, the CDC reduced the blood lead threshold that should raise concerns from 10 μg/dL to 5 μg/dL. The agency estimates that more than 500 000 children aged 1 to 5 years have blood lead levels higher than 5 μg/dL.
