Effect of cadmium on the extracellular Na⁺, K⁺, and Ca²⁺ in the gill and small intestine of goldfish Carassius auratus.

Abstract:

:In this study, the toxic effect of cadmium on extracellular Na(+), K(+), and Ca(2+) in the gill and small intestine of goldfish Carassius auratus was determined with the technique of ion chromatograph. Two-way ANOVA indicated that the two factors (Cd(2+) treatment and time) and the interaction factor had significant effect on the level of Na(+), K(+), and Ca(2+) in the small intestine and gill. 1.0 mg/L Cd(2+) significantly increased Ca(2+) level in the small intestine, but Ca(2+) level in the gill was significantly decreased by 1.0 and 5.0 mg/L Cd(2+) at 24, 48, and 72 h. Na(+) and K(+) level in the small intestine and gill was increased by 1.0 mg/L Cd(2+) at three time points, but increased by 5.0 mg/L Cd(2+) at a certain different time. In addition, Na(+) level was significantly decreased by 5.0 mg/L Cd(2+) at 24 or 48 h in the small intestine and gill. The results indicated that Cd(2+) played an important role in regulating the level of Na(+), K(+), and Ca(2+) in the small intestine and gill of goldfish C. auratus. A method was constructed to investigate the extracellular Na(+), K(+) and Ca(2+) in the tissues of gold fish with ion chromatography.
