Uptake and elimination of naphthalene from liver, lung, and muscle tissue in the leopard frog (Rana pipiens).

The effects of a 0-12-hour naphthalene exposure on pulmonary CO(2) excretion and bioaccumulation in the leopard frog, Rana pipiens, were investigated. The data showed that naphthalene transport occurred from the aqueous phase into the frog tissue. The first-order rate constant (k in day-1) for the entry of naphthalene from the water into the frog was 0.
