PROGRAM
Abby J. Greenberg, MD, FAAP

David Forte, Sanitarian
Overview
• One of the most preventable childhood health
problems
• Children susceptible due to rapid G & D and hand
to mouth behavior
• ¼ of the nation’s children are exposed at home
• 400,000 children nationwide are lead-poisoned
each year
• Principle source: lead-based paint
• NYS Physicians are required to test
• Current emphasis: primary prevention
History of NCDOH CLPPP
• 1970’s-CDC grant to identify children with lead
poisoning, 9 positions, assigned to community
testing
• 1980’s -  funding, 1 employee, case management
• Late 1980’s - grant from NYSDOH-case
management and Head Start testing
• 1990’s – present - expanded grant from NYSDOH
– expanded case management, education,
environmental assessment
• 1992 – Public Health Campaign – laboratory
development for lead testing
CDC Acceptable BLL
Table 1. Changing definitions of acceptable blood lead levels
in the United States
Year Level of Concern
1960 60 mcg/dL
1970 40 mcg/dL
1975 35 mcg/dL
1985 25 mcg/dL
1991 10 mcg/dL
2004 Discussions underway at CDC to determine if level
should be further decreased to 5 mcg/dl, in light of growing
body of research demonstrating no "safe" threshold of exposure
