Pesch B, et al. - Among elderly men from an industrial area with steel production, the authors examined the association between former exposure to manganese (Mn) and fine motor deficits. Evidence was found that exposure to inhalable Mn could carry a risk for dexterity deficits. Since airborne Mn was strongly correlated with iron in metal fumes, and high ferritin was also correlated with errors in line tracing, determining if these deficits were exclusively attributed to Mn required further analysis. Furthermore, when testing for fine motor skills, hand training effects ought to be taken into account.
