Bioavailability of soilborne lead in adults, by stable isotope dilution.

Using stable isotope dilution, we determined the bioavailability of soilborne lead (Pb) in
human adult volunteers. Soil from a residential yard at a mining-impacted federal Superfund
site that had negligible amounts of other priority pollutants was dried and screened through
a 25-micron mesh sieve. The< 250-micron fraction, which likely represents that ingested via
hand-to-mouth activity, was then sterilized by exposure to radiation. Ten replicate samples
yielded a mean (SD) soil Pb concentration of 2924+/-36 ppm, and a mean 206Pb/207Pb …
