Associations between blood lead, olfaction and fine-motor skills in elderly men: Results from the Heinz Nixdorf Recall Study

In this community-based cohort of elderly men, we could confirm indication of an influence of elevated PbB on odor identification. Small numbers of men with elevated PbB due to an on-going trend of decreasing PbB in the general population, strong covariates and multiple comparisons hamper the evaluation of adversity of these effects of PbB on olfaction and dexterity.
