John A. Serafin 1984 <p>1. Intestinal absorption of a polychlorinated biphenyl, dieldrin, and mercury (from HgCl₂) was measured in adult Northern bobwhites, Eastern screech owls, American kestrels, black-crowned night-herons and mallards <i>in vivo</i> by an <i>in situ</i> luminal perfusion technique.</p><p>2. Bobwhites, screech owls and kestrels absorbed much more of each xenobiotic than black-crowned night-herons and mallards.</p><p>3. Mallards absorbed less dieldrin and mercury than black-crowned night-herons.</p><p>4. Mercury absorption by kestrels was more than twice that in screech owls and eight times that observed in mallards.</p><p>5. Pronounced differences in xenobiotic absorption rates between bobwhites, screech owls and kestrels on the one hand, and black-crowned night-herons and mallards on the other, raise the possibility that absorptive ability may be associated with the phylogenetic classification of birds.</p> application/pdf 10.1016/0742-8413(84)90120-8 en Elsevier Avian species differences in the intestinal absorption of xenobiotics (PCB, dieldrin, Hg²⁺) article
