Data from the Adult Blood Lead Epidemiology and Surveillance program of the Centers for Disease Control NIOSH study for the third quarter of 1995 were presented. During July through September of 1995 there were 5,410 reports of blood lead levels exceeding 25 micrograms/deciliter (microg/dl), representing a 14% decrease from the third quarter in 1994. Compared with the third quarter of 1994, the number of reports for the same period in 1995 decreased 11% at the 25 to 39microg/dl level, 29% at the 40 to 49microg/dl level and 11% at the 50 to 59microg/dl level. They increased 23% at the 60microg/dl level. For the first three quarters of 1995 the cumulative reports of blood lead levels greater than 25microg/dl decreased by 4% from those for the same period of 1994. The number of reports increased only at the lowest reporting level, 25 to 39microg/dl, and decreased at all higher reporting levels. Compared with quarterly data from 1994, the number of reports increased at the highest blood lead level by 4% in the second quarter and again by 23% in the third quarter of 1995. In both quarters the reports at all lower blood lead levels decreased. An editorial note suggests that the variation in national quarterly reporting totals may result from changes in the number of participating states, timing of receipt of laboratory blood lead level reports by state based surveillance programs, changing in staffing and funding in stage based surveillance programs, and interstate differences in worker blood lead level testing by lead using industries. The findings still document the continuing hazard of work related lead exposures as an occupational health problem in the United States.
