Article

Summary

No difference was found between the nerve conduction velocities of the ulnar nerve of 32 lead exposed workers in the mill of a lead-zinc mine, compared to that of a control group of 14 persons. The lead exposure period was 2–37 months (mean: 12.9 months).

The blood lead of the exposed group was as an average (± SD): 53 ± 16 μg per 100 ml compared to 11 ± 4 μg per 100 ml for the control group.

Further studies are needed to establish a possible dose-time-response relationship for the possible, subclinical neuropathy found by some investigators.
