| Abstract |
The gastrointestinal absorption of arsenic from soil samples collected from residential properties at the Butte Arsenic Superfund site was measured using young swine. Test materials include composite soil with arsenic concentrations of 234 ppm (TM1) and 367 ppm (TM2). Groups of animals (four animals per dose group) were given oral doses of reference material (sodium arsenate) or test material twice a day for 12 days. Urine excreted by each animal was collected on days 6-7, 8-9 and 10-11. The urinary excretion fraction (UEF) (the ratio of the amount excreted per 48 hours divided by the dose given per 48 hours) was calculated for each test material using linear regression analysis. |
