WebIn 1931 Root reported that the presence of CO 2 markedly reduced the oxygen content of the blood of toadfish, sea robin, and mackerel, and caused the oxygen dissociation curve of the hemoglobin to become “nearly asymptotic with respect to the abscissa before saturation is complete”, which is still a valid description of the Root effect (cf. Brittain 1987).
