“…Reviewed articles indicate that surveillance and screening practices have extended considerable amount of importance in targeting "at-risk" populations. However, the literature shows that some health departments failed to account for "at-risk" populations [7][8][9]. This issue can be resolved through the implementation of GIS in health departments.…”

“…Identification of environmental risk factors and understanding of the distribution of the lead in the environment is important for health departments in better targeting at risk populations [6][7][8][9]. Ecological studies modeling risk factors are also valuable because they give insight to public health intervention strategies [10][11][12][13][14][15][16][17][18].…”

“…Public health departments recognized the advantages of GIS in screening, exposure prediction, and mapping cases. Using BLL data for lead poisoning, an increasing number of GIS-based ecological studies have identified risk factors as socioeconomic status (SES) [9][10][11][12][13][14][15][16][17][18]21], year built of housing [7][8][9][10][11]13,[15][16][17][18]20,21,23,28], race [11,13,14,16,17,21,23,27,28] and ethnicity [15,16,18].…”

“…At the data preparation stage, address geocoding is the most used tool to transfer tabular data sets, such as screened children addresses, into GIS [7][8][9][10][11][12][13][14][15][16][17][18][19]23]. Various GIS functions were used for multivariate mapping of BLLs and risk factors in a limited custom such as linking SES data with screened data records [49,50], map overlays [51,52], distance calculations [53], and hyperlinks to demolishing sites' photos and city maps for mapping dust-fall lead loadings [54].…”

Childhood exposure to lead remains a critical health control problem in the US. Integration of Geographic Information Systems (GIS) into childhood lead exposure studies significantly enhanced identifying lead hazards in the environment and determining at risk children. Research indicates that the toxic threshold for lead exposure was updated three times in the last four decades: 60 to 30 micrograms per deciliter (µg/dL) in 1975, 25 µg/dL in 1985, and 10 µb/dL in 1991. These changes revealed the extent of lead poisoning. By 2012 it was evident that no safe blood lead threshold for the adverse effects of lead on children had been identified and the Center for Disease Control (CDC) currently uses a reference value of 5 µg/dL. Review of the recent literature on GIS-based studies suggests that numerous environmental risk factors might be critical for lead exposure. New GIS-based studies are used in surveillance data management, risk analysis, lead exposure visualization, and community intervention strategies where geographically-targeted, specific intervention measures are taken.
