Abstract :In this study, the presence of heavy metals (Fe, Cu, Mn, Zn, Cd, Co and Pb) in the muscle tissue of Hemiramphus archipelagicus Collette & Parin, 1978 and Hemiramphus far (Forsskål, 1775) caught in the Ibrahim Hyderi Fish Harbor, Karachi, Pakistan was investigated. The concentration ranges of trace elements in muscles tissue of Hemiramphus archipelagicus and Hemiramphus far were found as follows, respectively: Fe: 19.570 - 62.140 µg g-1; Cu: 0.120 - 1.770 µg g-1; Mn: 0.001 -0.080 µg g-1; Zn: 7.230 - 36.450 µg g-1; Cd: 0.001 - 0.008 µg g-1; Co: 0.001 - 0.008 µg g-1; Pb: 0.002 - 0.080 µg g-1; Fe: 16.320 - 63.250 µg g-1; Cu: 0.130 - 1.220 µg g-1; Mn: 0.010 -0.080 µg g-1; Zn: 7.260 - 20.160 µg g-1; Cd: 0.000 - 0.008 µg g-1; Co: 0.000 - 0.001 µg g-1; Pb: 0.010 - 0.080 µg g-1. Metal concentrations in muscle tissues of Hemiramphus archipelagicus and Hemiramphus far were decreased as follows, Fe>Zn>Cu>Mn>Pb>Cd>Co. All metal accumulations in muscle tissues of Hemiramphus archipelagicus and Hemiramphus far samples collected from Ibrahim Hyderi Fish Harbor were not to be exceeding the limit and all values are under the permissible range. Therefore, it is important to continue to protect the Ibrahim Hyderi Fish Harbor against possible dangers that may increase heavy metal pollution, to ensure that the measures taken are maintained in the same way and to carry out regular controls.
