Summary
Blood lead concentrations of male subjects presenting for preemployment examination during the period 1967–1969 have been compared with those obtained during the period 1978–1980. A statistically significant reduction of the geometric mean value from 20.2 μg Pb/100 ml whole blood to 16.6 μg Pb/100 ml whole blood has been found.
