To comply with Rhode Island law, health care providers in Rhode Island must screen children between nine months and six years of age for lead annually. About 3/4 of children have had one test by 18 months, and about 40 percent have had two or more blood lead tests by 36 months of age.
In this report, you can compare the percent of childhood lead exposure for Rhode Island's cities and towns over time. Use the time slider tool to change the year of the data in the map and the table. Select a subset to limit the results to a RI county or the core cities.
The map uses the current CDC reference value of 5 micrograms of lead per deciliter of blood (µg/dL), while the table allows you to view the percents and numbers for 5 and above, 10 and above, and 20 and above. The CDC reference level (5 µg/dL) indicates that a child's blood lead level is much higher than most children in the country, falling in the top 2.5 percent. Previously, the CDC used a blood lead "level of concern" of 10 µg/dL.
All children under age six with confirmed blood lead tests and valid addresses are included. Rates are calculated based on the maximum test per child. The denominator is all children tested for lead by town by year. Each child's address was determined by taking the first address of his or her maximum test.
Data are suppressed (represented by a value of -1) for cities and towns with 1-4 cases of lead exposure in the given category and for cities and towns with less than 30 children tested in a given year.
