The Algerian coast receives significant inputs of metallic pollutants. To assess the accumulation of potentially toxic elements (Pb, Cd, Hg) by benthic fish and the consequent health risks for consumers, red mullet specimens (Mullus barbatus barbatus, Linnaeus, 1758) were sampled (n=424) in 3 sites along the Algerian coast (Algiers, Bejaia and Dellys) and analysed for Pb, Cd and Hg in muscles and liver. Spatio-temporal and biological variations were highlighted. The highest concentrations were observed in the liver for the three elements. Mean Pb and Cd concentrations are higher in Algiers specimens. However, the specimens from Dellys are more contaminated by Hg in the liver (0.35$\pm 0.0001\mathrm{\mu }$g/g). Medium and large specimens show higher concentrations of the three metals. There was no clear seasonal pattern in concentration of Pb, while Hg concentrations are higher in autumn, and Cd in summer, spring and winter. No impact of the three metal elements on Fulton’s K and the hepato-somatic indexes was observed. Despite the average concentrations of Pb and Cd exceeded the recommended regulatory values, few risk related to the consumption of contaminated M. barbatus barbatus inhabiting the Algerian coasts were demonstrated.

阿尔及利亚海岸接收大量金属污染物输入。为了评估底栖鱼类潜在有毒元素（Pb、Cd、Hg）的积累以及随之而来的消费者健康风险，我们在沿河的 3 个地点采集了红鲻鱼标本（Mullus barbatus barbatus，Linnaeus，1758）（n=424）。阿尔及利亚海岸（阿尔及尔、贝贾亚和德利斯）并分析肌肉和肝脏中的 Pb、Cd 和 Hg。强调了时空和生物变异。在肝脏中观察到三种元素的最高浓度。阿尔及尔标本的平均铅和镉浓度较高。然而，来自 Dellys 的标本在肝脏中受到更多的汞污染（0.35$\pm 0.0001\mathrm{\mu }$克/克）。中型和大型样品显示出更高浓度的三种金属。Pb浓度没有明显的季节性规律，秋季Hg浓度较高，夏季、春季和冬季Cd浓度较高。未观察到三种金属元素对富尔顿 K 值和肝-体细胞指数的影响。尽管 Pb 和 Cd 的平均浓度超过了推荐的监管值，但几乎没有证明与食用生活在阿尔及利亚海岸的受污染M. barbatus barbatus相关的风险。
