title: Intestinal absorption of 5 chromium compounds in young black ducks (Anas rubripes).
abstract: An in vivo intestinal perfusion technique was used to measure the absorption rates of five Cr compounds in black ducks. Cr was absorbed from saline solutions of KCr(SO4)2 and CrO3 at a rate about 1.5 to 2.0 times greater than from solutions of Cr, Cr(NO3)3, and Cr(C5H7O2)3. These results suggest the ionic form of Cr in solution may be an important factor in determining absorption of Cr compounds from the small intestine.
