The concentrations of four trace metals (Cd, Cu, Pb, and Zn) were investigated for the first time in phytoplankton, zooplankton, and the seawater samples collected from the coast of Gabès, Tunisia, Mediterranean Sea. For over 40 years, this coast has witnessed significant anthropogenic impacts form fertilizer processing. Results obtained for Cd, Cu, Pb, and Zn in seawater far exceed the concentration reported for other Mediterranean coastal waters, highlighting the Gulf of Gabès as a pollution hotspot. The average metals concentration was in the order Zn > Pb > Cu > Cd in water, and phytoplankton, whereas Pb > Zn > Cu > Cd in zooplankton. The biomagnification in phytoplankton and zooplankton for Zn, Pb, Cu, and Cd was 116, 56, 38, 31, and 127, 157, 30 and 27. The biomagnification of Zn and Pb was higher in zooplankton than phytoplankton, while Cu and Cd were higher in phytoplankton.
首次对突尼斯加贝斯海岸采集的浮游植物、浮游动物和海水样本中的四种痕量金属（Cd、Cu、Pb 和 Zn）的浓度进行了研究。四十多年来，该海岸受到了来自化肥加工的显著人为影响。海水中 Cd、Cu、Pb 和 Zn 的浓度远远超过了其他地中海沿海水域的报道浓度，突出了加贝斯湾是一个污染热点。在海水中和浮游植物中，金属浓度的顺序为 Zn > Pb > Cu > Cd，而在浮游动物中则为 Pb > Zn > Cu > Cd。Zn、Pb、Cu 和 Cd 在浮游植物和浮游动物中的生物放大倍数分别为 116、56、38、31 和 127、157、30 和 27。Zn 和 Pb 在浮游动物中的生物放大倍数高于浮游植物，而 Cu 和 Cd 在浮游植物中的生物放大倍数更高。
