Relations between individual and neighborhood-based measures of socioeconomic position and bone lead concentrations among community-exposed men: The Normative Aging Study

Article Abstract:

It appears that influence of individual socioeconomic class on cumulative lead exposure is affected by geographic area conditions. The relationship between individual and neighborhood-based measures of socioeconomic position and bone lead concentrations in community-exposed men has been investigated using data from the Normative Aging Study in 1960s Boston, MA. Measures of education, poverty and social class were used by linking records to 1990 US Census block group data. Tibia lead concentrations were higher in men who were not high school graduates than in those with 4 of more years of college. For non-hghi school graduates in an undereducated area tibia lead level was higher vs a non-undereducated locale.

The independent contribution of bone and erythrocyte lead to urinary lead among middle-aged and elderly men: the normative aging study

Article Abstract:

Researchers studied the influence of bone and erythrocyte lead on plasma lead levels to determine methods for measuring lead toxicity. The effect of bone lead on plasma lead appears to be a better indicator of toxicity than blood lead. Urinary lead measurement, instead of plasma lead, is considered useful in studies of lead toxicity.
