In this study, levels of 20 trace elements (Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Ag, Cd, Sn, Sb, Ba, Hg, Pb and U) and the respective biota–sediment accumulation factors (BSAF) were assessed for three marine species from the Eastern Mediterranean (Lebanese coast) belonging to different trophic levels in the food chain (algae, bivalves and shrimps). Multivariate analyses showed significant differences in trace element accumulation between seasons, sites and species thus highlighting the importance of a multi-species and seasonal approach to monitor trace metals in coastal areas. Biota–sediment accumulation factors (BSAF) showed limited transfer from sediments to marine organisms suggesting that the bioaccumulation of trace elements by marine organisms should be assessed by considering multiple sources of contaminants. Lead (Pb) levels (0.07–4.44​ mg.kg⁻¹) measured in algae and Cd (0.54–7.74 mg.kg⁻¹) and Zn (42.88–972​ mg.kg⁻¹) levels found in the oyster, were similar and sometimes higher than those found in other polluted areas indicating that the Lebanese coast is subject to environmental pollution.

在这项研究中，对20种微量元素（Al，Ti，V，Cr，Mn，Fe，Co，Ni，Cu，Zn，As，Se，Ag，Cd，Sn，Sb，Ba，Hg，Pb和U）的含量进行了研究并对来自地中海东部（黎巴嫩海岸）的三种海洋物种（食物，藻类，双壳类和虾类）的营养水平不同，分别评估了其生物沉积物累积因子（BSAF）。多变量分析显示季节，地点和物种之间痕量元素积累的显着差异，从而突出了采用多物种和季节性方法来监测沿海地区痕量金属的重要性。生物沉积物累积因子（BSAF）显示出从沉积物到海洋生物的转移有限，这表明应通过考虑多种污染物源来评估海洋生物对微量元素的生物累积。铅（Pb）含量（0。^-1）在藻类和Cd（0.54-7.74 mg.kg测量^-1）和Zn（42.88-972 mg.kg ^-1）的水平在牡蛎发现，是类似的，比其他污染地区发现有时更高指示黎巴嫩海岸受到环境污染。
