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.

首次调查了浮游植物，浮游动物中四种痕量金属（镉，铜，铅和锌）的浓度，以及从地中海突尼斯加贝斯海岸收集的海水样品。40多年来，这个海岸见证了肥料加工对人为的重大影响。海水中Cd，Cu，Pb和Zn的结果远远超过了其他地中海沿岸水域所报告的浓度，这突显了Gabès海湾是一个污染热点。水中和浮游植物中的平均金属浓度依次为Zn> Pb> Cu> Cd，而浮游动物中的Pb> Zn> Cu> Cd。浮游植物和浮游动物中Zn，Pb，Cu和Cd的生物放大倍数分别为116、56、38、31和127、157、30和27。
