According to the Centers for Disease Control and Prevention (CDC), about 1.4% of surveyed children living in the United States between the ages of 1 and 5 years had an unacceptably high level of lead in their blood (i.e., 10 micrograms or more of lead per deciliter [i.e., one-tenth of a liter] of blood) between 1999 and 2004. Elevated blood-lead levels may result in learning disabilities, reduced intellectual ability, or other problems. Poor children are at special risk because elevated blood-lead levels are more prevalent among children from families with lower incomes, and inadequate nutrition can increase lead absorption by the body. The drop in blood-lead levels since 1994 may have resulted, at least in part, from the success of federal, state, and local programs aimed at reducing childhood exposure to sources of lead, including house dust containing lead-based paint (LBP) from deteriorated or abraded surfaces of walls, door jambs, and window sashes. Many buildings constructed prior to 1978, when the lead content of interior paint was restricted to current levels, still contain LBP, although most of the lead is found in the existing 18.4 million homes constructed prior to 1960. Federal Mandates

The Lead-Based Paint Poisoning Prevention Act, as amended (LBPPPA, 42 U.S.C. 4822), is the basis for federal regulation of LBP hazards. It directs HUD to establish procedures to eliminate "as far as practicable" LBP hazards in all public housing and private housing constructed prior to 1978 that receive federal financial assistance. There are no federal mandates related to LBP in privately owned housing unless it receives federal financial assistance in some form. Federal Grants

The Residential Lead-Based Paint Hazard Reduction Act of 1992 (Title X of the Housing and Community Development Act of 1992) authorizes federal grants to state and local governments that choose to establish LBP poisoning prevention programs targeted at low-income residents in private housing.

Poor children are at special risk because elevated blood-lead levels are more prevalent among children from families with lower incomes, and inadequate nutrition can increase lead absorption by the body. Many sources of lead exposure have been eliminated or reduced, but an important remaining source of lead exposure today is house dust containing lead-based paint (LBP) from deteriorated or abraded surfaces of walls, door jambs, and window sashes, or from home renovations that release LBP. Many buildings constructed prior to 1978, when the lead content of interior paint was restricted to current levels, still contain LBP, but most LBP is found in homes constructed prior to 1960.
The federal Lead-Based Paint Poisoning Prevention Act (LBPPPA), as amended, directs the Department of Housing and Urban Development (HUD) to regulate, and authorizes funding for, the detection and control of LBP hazards in housing that receives federal assistance. There are no federal mandates related to LBP in privately owned housing unless it receives federal financial assistance in some form. However, the Residential Lead-Based Paint Hazard Reduction Act of 1992 (Title X of the Housing and Community Development Act of 1992; P.L. 102-550) directs the U.S. Environmental Protection Agency (EPA) to require training and certification in LBP safe work practices for contractors engaged in home renovations and repairs of homes constructed prior to 1978. In addition, Title X authorizes federal grants through HUD to state and local governments for LBP hazard reduction in privately owned housing that does not receive federal assistance. Congress annually considers funding for these lead hazard reduction grant programs, all of which target older (pre-1978) housing for low-income residents.
