Resumo1. Chronic F− doses of NaF (40 and 80mg F−/kg per day) given to adélie penguins for 6–7 weeks led to a significant increase in F− concentrations of nasal salt secretions with 1.16 and 2.22μg F−/g (wet wt) respectively as opposed to 0.66 μg F−/g in controls. 2. Single oral administration of 6 mg fluoride as NaF to mallard ducks led to increased F− concentrations in the nasal salt secretions, with a mean of 0.67μg F−/g as opposed to 0.11 μg F−/g in controls. 3. In mallard ducks as well as in adélie penguins the amount of F− excreted via the cloaca was 103-104 times that excreted via the nasal salt glands.
