This paper presents the results of a seasonal survey of heavy metals accumulated in sediments and in the soft parts of the body of the mussel Perna perna at four stations in the Gulf of Annaba (Algeria). Pooled soft tissues from 10 mussels representing the entire range of sizes were digested in nitric acid. Statistical analysis reveals a significant seasonal effect on all the measured metals, the highest values being recorded in winter. With the exception of Cr, the levels for all metals were significantly higher in the east, at the outlet of the Seybouse River, than at all other monitoring stations. The study also shows that north-western waters are subject to a significantly lower degree of heavy metal pollution than elsewhere in the gulf. Levels were nevertheless within the limits of public health standards. The results confirm the usefulness of P. perna as a bioindicator for heavy metal pollution.
本研究报告介绍了在阿尔及利亚安纳巴湾（Gulf of Annaba）的四个站位，对贻贝 Perna perna 体内沉积物和软体组织中重金属积累情况进行季节性调查的结果。对 10 只代表所有大小范围的贻贝的软体组织进行混合，在硝酸中进行消化。统计分析显示，所有测量金属均具有显著的季节性影响，冬季的浓度最高。除了 Cr，所有金属的含量都明显高于东侧，即塞布河（Seybouse River）的出水口，而其他监测站的含量则较低。该研究还表明，与海湾其他地区相比，西北部水域的重金属污染程度要低得多。但含量仍在公共卫生标准范围内。结果证实了贻贝 Perna perna 作为重金属污染生物指示剂的有用性。
