Notice to Readers Adult Blood Lead Epidemiology and Surveillance -- United States, Second Quarter, 1994

CDC's National Institute for Occupational Safety and Health (NIOSH) Adult Blood Lead Epidemiology and Surveillance program (ABLES) monitors elevated blood lead levels (BLLs) in adults in the United States. Blood lead data from laboratory reports are transmitted to state-based lead surveillance programs and are compiled by NIOSH for quarterly reporting (1).

The cumulative number of BLL reports for the first and second quarters of 1994 increased 29% over those of the same period for 1993 Table_1. This finding is consistent with a previous ABLES report describing the increasing number of reports of elevated BLL cases among U.S. workers during 1992-1993 (2).

Reports of elevated BLLs represent new, ongoing, or recurrent exposures and illustrate the extent and ongoing nature of elevated BLLs in workers in lead-using industries. Factors that help explain the increase in reports include increased testing of workers in construction trades (3), improved case ascertainment by state-based surveillance programs, and increased numbers of participating states. Finally, during this quarter, the number of persons reported apparently exceeded the number of reports in one reporting category (25-39 ug/dL) because one large industrialized state reports only numbers of persons on a quarterly basis and compiles overall numbers of reports only annually Table_1.
