Trace metals were examined in the muscle tissue of flatfish species of flounder, Platichthys flesus (Linnaeus, 1758), sediments from two southern Baltic Sea sites (Gdańsk Bay and Ustecko-Łebskie as a reference) and in two areas of the Portuguese Atlantic coast (Douro River estuary and Atlantic fishing ground as a reference) to evaluate spatial differences in trace metals. Additionally, the accumulation of trace metals in flounder of different length classes was assessed. Flounder from the Gdańsk Bay area contained twofold more cupper (Cu), lead (Pb) and mercury (Hg) than did flounder from the Douro River estuary, but zinc (Zn) and cadmium (Cd) were at similar concentrations. The sediments from Gdańsk Bay contained significantly more Zn and threefold more Cd, while concentrations of Cu and Pb were twofold lower. The concentrations of metals in the sediments did not correlate with those in the flounder. Spatial differences were noted in metal concentrations in flounder from the southern Baltic Sea and the Portuguese Atlantic coast as well as within these regions, with higher concentrations in the flounder from the Baltic Sea Gdańsk Bay. The flounder in length class 25-30 cm from Gdańsk Bay contained metal concentrations comparable to those of class 40-45 cm specimens from the Atlantic coast. The accumulation of metals in flounder length classes differed in the two regions.
研究了比目鱼属鱼类（Platichthys flesus (Linnaeus, 1758）的肌肉组织、来自波罗的海南部两个地点（格但斯克湾和乌斯特卡-莱布日采湾作为参考）和葡萄牙大西洋沿岸两个地区（杜罗河口和大西洋渔区作为参考）的沉积物中的痕量金属，以评估痕量金属的空间差异。此外，还评估了不同长度类别的比目鱼中痕量金属的积累情况。格但斯克湾地区的比目鱼体内铜（Cu）、铅（Pb）和汞（Hg）的含量是杜罗河口的两倍，但锌（Zn）和镉（Cd）的含量相似。格但斯克湾的沉积物中 Zn 含量明显较高，Cd 含量高 3 倍，而 Cu 和 Pb 的浓度低 2 倍。沉积物中的金属浓度与比目鱼体内的金属浓度没有相关性。来自波罗的海南部和葡萄牙大西洋沿岸的比目鱼以及这些地区内部的金属浓度存在空间差异，波罗的海格但斯克湾的比目鱼金属浓度更高。格但斯克湾 25-30cm 长度类别的比目鱼体内的金属浓度与大西洋海岸 40-45cm 长度类别的比目鱼体内的金属浓度相当。两个地区的比目鱼在不同长度类别的金属积累情况不同。
