Abstract |
The influence of long-term exposure to lead on perceptual-motor performance was studied in 109 workers of a copper smelter in the Land of Saxony-Anhalt, Germany (ex-GDR). The workers had been exposed throughout a 10-year period to permissible lead concentrations of somewhat above 0.025mg/m3, which amounted to somewhat more than one quarter of the exposure limit. The average blood lead level amounted to 31.2µg/dL which was less than half the biological threshold limit. The performance of the lead-exposed workers in 7 computer-aided psychometric tests was compared to that of a non-exposed control group of 27 workers of a mechanical engineering plant. No statistically significant relationship between the blood lead levels and the perceptual-motor performance was found for the exposed group. It is concluded that perceptual-motor performance is not a good indicator of the latent effects caused by a long-term sub-clinical exposure to lead. |
