Abstract

This study was performed to investigate the contamination level of harmful metals in 4 species of freshwater fishes collected at the three sampling sites of Yeong san river from January to October in 1990. The levels of total mercury, lead, zinc, manganese, copper and cadmium were ditermined and the results were summarized as follows : The overall range(ppm) were Hg, 0.022~0.139 ; Pb, 0.666~0.984 ; Zn, 8.673~15.214 ; Mn, 2.751~5.049 ; Cu, 0.328~1.174 ; Cd, 0.017~0.052. Among the six heavy metals contents, the highest was zinc and the lowest was cadmium. The results showed that all the 4 species of freshwater fishes of Yeong san river studied have not yet dangerous levels enough to pose a health problem.
