Resumo: | The objective of this paper was to determine nitrate and nitrite anions in toasted fish skin tea, which the population of southern Rio Grande do Sul believes to have pharmacological properties for trating asthma. Two methods were compared, an official and one described by Guozhen et al., that has the advantage of not needing reduction of nitrate to nitrite on a Cd column. The samples were the skin of the fish species Balistes capriscus (peixe porco) and Menticirrhus littoralis (papa-terra), both crude and toasted, as traditionally used. The method of Guozhen et al. was used due to its performance (detection limit 0.005 μmol/L NO3 - and 0.02 μmol/L - NO2 - and mean recuperation of 100 and 97% respectively for each anion) and results similar to those of the official methods under conditions used by the population, the estimated daily intake, of the teas is equivalent to 0.03 to 0.05 mg of nitrate and 0.007 to 0.014 mg of nitrite. These values are in accord with safety recommendations and don’t represent a health risk. |
