Effects of increased lead absorption in lead workers.
NIOSH 1979 Aug; :1-3
The effects of increased lead (7439921) (Pb) absorption on lead smelter workers were surveyed. Sixty nine lead workers with blood Pb concentration between 60 and 80 micrograms per deciliter were given a comprehensive baseline physical examination and then evaluated longitudinally for 12 to 18 months. There were no significant differences between lead workers and comparisons on audiometric tests, nerve conduction measurements, or frequency of minor neurologic signs. Lead workers reported more symptoms than comparison workers, but no pattern of symptoms was found among Pb workers. On initial test and retest, saccade eye movements were generally less accurate in the Pb exposed workers. The author concludes that there is no evidence of subclinical effects in smelter workers with blood Pb concentrations less than 80 micrograms per deciliter.
