Resumo
The characterization of edible tissues of fishes consumed by humans is very important
for determination of several toxic and potentially toxic elements, ensuring
the food safety. The Instrumental Neutron Activation Analysis (INAA) comparative
method allows the determination of several of these elements, as well as others, for
example of nutritional character. This study is part of the International Atomic Energy
Agency (IAEA) technical cooperation project of Latin America and Caribbean
countries to ensure the quality of food and biomonitoring of contaminants in molluscs
and fishes. Ten specimens of 5 of the most consumed fish in São Paulo
city: whitemouth croaker (Micropogonias Furnieri), smooth weakfish (Cynoscion
learchus), common snook (Centropomus undecimalis), Brazilian sardine (Sardinella
brasiliensis) and bluefish (Pomatomus Saltatrix) were analyzed. Complete procedures
for analysis, which includes purchase in the largest warehouse in Latin America,
transport to the laboratory, storage, freeze-drying, milling, weighting and other
preparations of the subsamples, and the short irradiation parameters for the determination
of Br, Cl, K, Mn and Na are reported. Results obtained for macro and
microelements are presented and are in agreement with analysis of oyster tissue and mussel tissue certified reference materials under the same irradiation conditions, with
zscore values ranging from -3.0 to 2.2.
