Two separate databases are maintained within the Public Health Toxicology Program. The first database contains information on children, age 15 years or younger, with an elevated blood lead level of greater than or equal to 10 micrograms of lead per deciliter of whole blood (µg/dL). The information is reported to the Virginia Department of Health by physicians, laboratories, hospitals, and medical facilities. Statistical analysis is performed on the number of reported cases by race, sex, age, range of elevation, population rates, locality, and health district.
The second database contains information on adults whose diagnostic test results indicate a possible exposure to a toxic substance. Examples of the reports include blood or urine test results for exposure to lead, cadmium, mercury, or arsenic. Information is also provided on individuals diagnosed with asbestosis or pneumoconiosis. The data is collected from physicians, laboratories, hospitals and other state agencies.
