Childhood Lead Poisoning Prevention in the 21st Century

In 2000, childhood lead poisoning remained a major environmental public health problem in the

United States, affecting children from all geographic areas and social and economic levels. Black

children and those living in poverty and in old, poorly maintained housing were disproportionately

affected. In 1990, five states had comprehensive lead poisoning prevention laws; by 2010, 23

states had such laws. Enforcement of these statutes as well as federal laws that reduce hazards

in the housing with the greatest risks has significantly reduced the prevalence of lead poisoning.

Findings of the National Health and Nutrition Examination Surveys from 1976-1980 to 2003-2008

reveal a steep decline, from 88.2% to 0.9%, in the percentage of children aged 1-5 years with

blood lead levels 10 g/dL. The risks for elevated blood lead levels based on socioeconomic

status and race also were reduced significantly. The economic benefit of lowering lead levels

among children by preventing lead exposure is estimated at $213 billion per year
