Figure 10: Incidence of Blood Lead Levels of ≥45 mcg/dL Among Children Under Age Six Years; 1998 to 2005 Blood Lead Test Data, New York State Excluding New York City.

Figure 10 shows the total number and rate of children under age six years newly identified with BLLs ≥ 45 mcg/dL by year of testing. In 2005, a total of 18 children were newly identified with BLLs ≥ 45 mcg/dL, corresponding to an incidence rate of 0.10 per 1,000 children tested for blood lead in that year (0.01% 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 33.3 % between 1998 and 2005, from 27 children in 1998 to 18 children in 2005. The incidence rate declined 40.0% over the same period, from 0.15 per 1,000 children tested in 1998 to 0.09 per 1,000 children tested in 2005.

Under current New York State 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 screening, 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.
