Abstract

This study assessed total selenium concentrations in the muscle tissues and liver samples of three fish species and also in the soft tissues of a bivalve. The samples were digested with concentrated acid and analyzed by GF-AAS using Zeeman background correction. Concentrations of selenium in the muscle tissue samples were higher in carnivorous fish. The liver samples of all studied fish species presented the highest total selenium concentration. The fish species presented a high positive correlation (Spearman) between their total lengths and total selenium concentration. A significant correlation was observed between the selenium concentration in the mussel soft tissues and the condition index (IC). All studied species presented the selenium concentrations in the muscle tissue and in the soft tissue below the safety limit established by WHO for human consumption (1.5 μg.g–1 in wet weight).
