Abstract
Silver iodide, a cloud seeding agent, was administered orally to 15 yearling ewes (5/group) at dose levels of 0.1, 1.0, or 10 mg kg−1 day−1 for 86 days without clinical signs of toxicosis. Erythrocyte and leukocyte counts, packed cell volumes, hemoglobin concentrations, and circulating thyroid hormone levels (T 3 and T 4) were not altered significantly in AgI-dosed ewes. Silver at dose levels of I or 10 mg AgI kg-1 body weight for 86 days, was absorbed from the gastrointestinal tract and deposited in soft and hard tissues of the body. The maximum Ag residue found was 17 ppm in the liver of a ewe receiving 10 mg kg−1 day−1.
