Abstract In this study, muscle samples collected from Planiliza subviridis (Valenciennes, 1836) and Ellochelon vaigiensis (Quoy & Gaimard, 1825) caught on the Balochistan coast (Damb Harbor) between January and December 2015 (during the northeast monsoon, post-monsoon and pre-monsoon seasons, and the southwest monsoon) were analyzed to determine concentrations of heavy metals: iron, zinc, copper, manganese, cadmium and lead by an atomic absorption spectrophotometer, expressed per unit of dry weight of each sample. The average measured level of Fe, Zn, Cu, Mn, Cd and Pb for P. subviridis was 26.70 ± 11.49 μg g−1, 13.82 ± 4.56 μg g−1, 1.66 ± 0.84 μg g−1, 0.24 ± 0.10 μg g−1, 0.06 ± 0.07 μg g−1 and 0.17 ± 0.14 μg g−1, respectively. The average level of the same metals for E. vaigiensis was 29.26 ± 10.18 μg g−1, 18.85 ± 6.28 μg g−1, 2.18 ± 1.01 μg g−1, 0.32 ± 0.14 μg g−1, 0.25 ± 0.11 μg g−1 and 0.30 ± 0.12 μg g−1, respectively. The highest Pb accumulation (0.56 μg g−1 and 0.61 μg g−1) detected in P. subviridis and E. vaigiensis is above the limit value (0.50 μg g−1) reported by FAO, hence the accumulation of Pb in these two fish species should be monitored in the future.

巴基斯坦俾路支省 Damb 港的鲻鱼 Planiliza subviridis (Valenciennes, 1836) 和 Ellochelon vaigiensis (Quoy & Gaimard, 1825) 中重金属（Fe、Zn、Cu、Mn、Cd 和 Pb）的积累

摘要 在这项研究中，从 2015 年 1 月至 12 月（东北季风期间、季风过后和季风前季节和西南季风）通过原子吸收分光光度计测定重金属的浓度：铁、锌、铜、锰、镉和铅，以每个样品的每单位干重表示。P. subviridis 的 Fe、Zn、Cu、Mn、Cd 和 Pb 的平均测量水平为 26.70 ± 11.49 μg g-1、13.82 ± 4.56 μg g-1、1.66 ± 0.84 μg g-1、0.24 ± 0.10 μg g -1、0.06±0.07μg-1和0.17±0.14μg-1分别。E. vaigiensis 相同金属的平均水平为 29.26 ± 10.18 μg g-1、18.85 ± 6.28 μg g-1、2.18 ± 1。分别为 01 μg g-1、0.32 ± 0.14 μg g-1、0.25 ± 0.11 μg g-1 和 0.30 ± 0.12 μg g-1。在 P. subviridis 和 E. vaigiensis 中检测到的最高 Pb 积累（0.56 μg g-1 和 0.61 μg g-1）高于 FAO 报告的限值（0.50 μg g-1），因此 Pb 在这两个中的积累今后应监测鱼类种类。
