The Children’s Environmental Health Initiative (CEHI)

Map demonstrates how the GIS model might shape preventive intervention programs. The intersections of Enterprise Street with South Street and Fayetteville Street with Dunbar Street (note the highlighted stars) represent two neighborhoods with high risk for lead exposure. The detail provided by these maps allows for block or even house-level planning for intervention programs.

The Nicholas School of the Environment and Earth Sciences at Duke University houses a program called The Children’s Environmental Health Initiative (CEHI), which is a research, education, and outreach program committed to fostering environments where all children can prosper. CEHI projects focus on incorporating innovative spatial analysis in combination with field-based sampling into children’s environmental health research.

An example of CEHI’s application of GIS technology is the Mapping for Prevention project, which uses GIS spatial analysis of county tax assessor, U.S. Census, and North Carolina blood lead screening data to categorize housing risk levels in multiple North Carolina counties. The map above is a sample priority mapping drawn from the Durham County GIS project to demonstrate how spatial analysis can help identify children at high risk for exposure to lead. Dark blue areas represent Priority One parcels, estimated to be most likely to contain lead paint hazards. Priority Two and Three parcels are colored medium and light green, respectively, and are less likely than Priority One parcels to contain lead paint hazards. Priority Four parcels are yellow and least likely to contain lead paint hazards. White areas represent commercial or industrial properties.
