Metals such as arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), nickel (Ni), lead (Pb), vanadium (V), have been determined in species of Mediterranean marine organisms collected from areas supposed to be at background contamination levels. The Inductively Coupled Plasma Mass Spectrometry (ICP-MS) approach was adopted for the determination of all the metals. Arsenic, Cd and Pb determined in the 42 samples, do not exceed the pertinent maximum level except a sample of hake. In wild fish, the concentration range for Cr, Ni, V and Cu was, respectively: 0.07-0.09, 87.6-124, 0.022-0.075 and 0.79-1.74 μg/g fresh weight (fw). The farmed fish samples show concentration levels below the wild fish ones, except for Cr which range at the same levels. Cadmium and Pb show a high sample number under the quantification limit. The elements do not bio-magnify among the species considered and appear to show low variations in relation to organisms' position in the food chain and at sampling sites.
已在从疑似背景污染水平地区采集的地中海海洋生物物种中检测到砷（As）、镉（Cd）、铜（Cu）、铬（Cr）、镍（Ni）、铅（Pb）、钒（V）等金属。采用电感耦合等离子体质谱法（ICP-MS）测定所有金属。在 42 个样本中，除了一个鳕鱼样本外，砷、Cd 和 Pb 的含量均未超过相关最高限量。在野生鱼类中，Cr、Ni、V 和 Cu 的浓度范围分别为：0.07-0.09、87.6-124、0.022-0.075 和 0.79-1.74μg/g 鲜重（fw）。养殖鱼类样本的浓度水平低于野生鱼类，除了 Cr 处于相同水平。Cd 和 Pb 的数量有很大一部分低于定量限。这些元素在考虑的物种之间没有生物放大，并且似乎与生物在食物链中的位置以及在采样点的位置相关的变化较低。
