Heavy metal pollution of the marine environment has toxic implications for both the aquatic biota and human health. We examined the levels of Zinc (Zn), Lead (Pb), Copper (Cu), Cadmium (Cd), Arsenic (As) and Mercury (Hg) in muscles of caught from the coastal waters of Ghana using inductively coupled plasma mass spectrometry method. recorded the highest concentrations of all the metals (Cu:12.08 ± 1.46 µg/g, Zn: 19.20 ± 2.27 µg/g, As: 8.46 ± 2.42 µg/g, and Cd: 0.03 ± 0.01 µg/g) except Hg. Mercury was relatively high in (0.14 ± 0.03 µg/g). Apart from As, all metals were within globally permissible daily limits for consumption by human per meal. The estimated Target Hazard Quotient due to the intake of Hg through D. consumption exceeded the threshold value across all age categories. Carcinogenic risks due to As intake through consumption far exceeded the 10 threshold for all age groups in Ghana It is recommended that the consumption of these fish species particularly, the shrimp be done cautiously to avoid possible future health challenges.
海洋环境中的重金属污染对水生生物群和人类健康都有潜在毒性影响。我们使用电感耦合等离子体质谱法检测了从加纳沿海水域捕获的[具体生物名称未给出]肌肉中锌（Zn）、铅（Pb）、铜（Cu）、镉（Cd）、砷（As）和汞（Hg）的含量。[具体生物名称未给出]记录了除汞以外所有金属的最高浓度（铜：12.08±1.46微克/克，锌：19.20±2.27微克/克，砷：8.46±2.42微克/克，镉：0.03±0.01微克/克）。汞在[具体生物名称未给出]中相对较高（0.14±0.03微克/克）。除了砷之外，所有金属都在全球人类每餐可食用的允许每日限量范围内。通过食用[具体生物名称未给出]摄入汞导致的估计目标危险商数超过了所有年龄组的阈值。在加纳，通过食用[具体生物名称未给出]摄入砷导致的致癌风险远远超过了所有年龄组的10的阈值。建议谨慎食用这些鱼类品种，特别是虾，以避免未来可能出现的健康挑战。
