Concentrations of Cu, Zn, Pb, Cd, Fe, Cr, Mn, As, and Hg were analyzed in muscle of ten fish species collected from the Chishui River, China. The results showed that mean concentrations of Cu, Zn, Pb, Cd, Fe, Cr, Mn, As, and Hg in the ten fish species were 0.363 +/- 0.106, 8.538 +/- 3.877, 0.340 +/- 0.233, 0.035 +/- 0.036, 8.450 +/- 4.959, 0.273 +/- 0.088, 0.351 +/- 0.110, 0.097 +/- 0.035, 0.058 +/- 0.033 mg/kg, respectively. There were no identical correlations between metal concentrations and fish length. The target hazard quotient (THQ) and hazard index (HI) exhibited higher potential risks in fishermen than that in general population. Compared with the maximum permissible levels according to China and European Commission, The results of metal concentrations in present study indicated that several kinds of fish from this study area could be not totally safe for human consumption.
