The development of registries for surveillance of adult lead exposure, 1981 to 1992.
OBJECTIVE
Since 1981, 15 states have established registries for surveillance of adult lead absorption, primarily based on reports of elevated blood lead levels from clinical laboratories. I review the status of the registries and recommend steps for further development.


METHODS
Companies reported to the New York registry are compared with those cited by the Occupational Safety and Health Administration (OSHA). I present data on US workers and plants with potential lead exposures and blood tests, as well as review registries' reporting requirements.


RESULTS
Registries identify many companies not cited by the Occupational Safety and Health Administration, but underreporting occurs because (1) reporting is usually not required from laboratories outside the state, (2) most registries use a blood lead reporting level of 1.21 mumol/L, which excludes many exposed workers, and (3) many companies with potential exposures do not have routine monitoring programs.


CONCLUSIONS
Registries' reporting requirements and procedures should be standardized, including a blood lead reporting level of 0.72 mumol/L. Elevated blood lead levels should be a reportable condition nationwide, and a comprehensive national surveillance system should be established: clinical laboratories should be required to report cases to those states with lead registries or directly to the national adult lead registry.
