Figure 8: Incidence of Elevated Blood Lead Levels ≥ 45 mcg/dL Among Children Under Age Six Years; 1998 to 2007 Blood Lead Test Data, New York State Excluding New York City

Figure 8 shows the total number and rate of children under age six years newly identified with BLLs ≥ 45 mcg/dL by year of testing. In 2007, a total of 16 children were newly identified with BLLs ≥ 45 mcg/dL, corresponding to an incidence rate of 0.08 per 1,000 children tested for blood lead in that year (0.008 percent of children tested).

Trend data show the dramatic improvement since 1998 in both the number and rate of children identified with incident BLLs ≥ 45mcg/dL. The total number of children newly identified with BLLs ≥ 45mcg/dL declined 40.7 percent between 1998 and 2007, from 27 children in 1998 to 16 children in 2007. The incidence rate declined 46.7 percent over the same period, from 0.15 per 1,000 children tested in 1998 to 0.08 per 1,000 children tested in 2007.

Under current NYS Public Health Law and regulations and CDC guidelines, children newly identified with BLLs ≥ 45 mcg/dL receive risk reduction education, a detailed lead exposure assessment, nutritional assessment including iron status, developmental testing, environmental management and follow-up testing to track blood lead levels. Environmental management includes detailed assessments of all dwellings where children spend significant time and remediation of suspected sources of lead exposure identified through those assessments. In addition, children with BLLs ≥ 45 mcg/dL require special medical treatment called chelation to help remove lead from their bodies. This treatment is performed under the supervision of a licensed health care provider.
