Biological half-lives of chlorinated dibenzo-p-dioxins and dibenzofurans in rainbow trout (Salmo gairdneri) [electronic resource] / A.J. Niimi and Barry G. Oliver. Burlington, Ont. : National Water Research Institute, Canada Centre for Inland Waters, [1985]. 7, [5] p. NWRI contribution ; 85-35 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "This paper indicates that chlorinated dioxins and dibenzofurans are poorly assimilated by fish from fish food. The large molecular size of these chemicals is likely the reason for the difficulty in transport across the stomach membranes. The small portion of these chemicals that are assimilated are quickly eliminated by the fish. These results help explain why the concentration of dioxins and dibenzofurans is so low in field fish (parts per trillion) even from sites which are fairly heavily contaminated with these chemicals. The low bioaccumulation potential of these compounds is indeed fortunate because of their extreme toxicity"--Management perspective.
