A survey of Chung-Kung sttream fish was undertaken on six occasions from March 1994 to August 1995. Tilapia (Oreochromis hybrid) and Liza macrolepsis were the major species found downstream and were chosen as the target species for metallothionein (MT) analysis of liver tissue. in total MT of 77 tilapia and 48 Liza macrolepsis liver samples were analyzed. Significantly higher values (p >0.05) were found for the August 1995 samples than for samples taken earlier at site B (6 km from the sea) for tilapia and at site A (estuary) for Liza macrolepsis. Liver zinc, copper and cadmium were analyzed for the 1995 samples. for tilapia, liver MT concentration was found to correlate well with zinc concentration (r = 0.84, p > 0.001). for Liza macrolepsis, good correlation was found for MT with both zinc (r = 0.89, p > 0.001) and copper (r = 0.90, p > 0.001). These results indicate that in the Chung-Kung stream, zinc and copper may be the major inducers of fish liver MT. Since these two species are ubiquitous in tropical areas, they would provide a good biomarker for evaluation of integrated metal exposure in the tropical aquatic environment. |
