Abstract
|
The purpose of this study was to determine the
concentrations of metals, cadmium, chromium, lead and
nickel in Liza vaigiensis and Johnius carutta, in order to:
compare metal concentrations between two species with
different gender, and to determine the significance between
metal concentrations in the gill, liver and muscle. The
highest mean concentrations of cadmium, chromium, lead
and nickel in different tissues of these two fish species were
found in the liver of L. vaigiensis at 0.68, 0.83, 0.37 and
1.42 lg g-1, respectively; while the lowest mean concentrations of cadmium, chromium, lead and nickel were
observed in the muscle of J. carutta at 0.16, 0.16, 0.03 and
0.29 lg g-1, respectively. The results showed that the
metal concentrations in both species were higher in the
females than in the males (except chromium in gill and
cadmium in muscle of J. carutta). Also, the results indicated that the metal concentrations were different among fish tissues (one-way ANOVA, p<0.001), but there was no difference (except lead in gills of J. carutta) between sex (male vs. female).
