Metals, whether essential (Cu, Zn, Cr, Fe, Mn) or non-essential (Al, As, Cd, Ni, Pb, Hg) for organism metabolism, occur naturally in the marine environment and their abundance can increase due to the presence of human activities. In this study, fish were used as bio-indicators, to determine a correlation between the bio-accumulation of metals in muscle and gill tissues and the health status of fish. The study area was the Gulf of Tigullio (north-western Italy), which is impacted by various sources of metal contamination. Histopathology served as a significant tool to investigate possible alterations in gills, one of the main organs involved in fish physiology. Results highlighted some correlations between certain metals (e.g. Pb, Ni) and gill alterations (e.g. epithelial hyperplasia, epithelial lifting), providing baseline data from a pool of different fish species, which can be used for comparison purposes in further studies.
金属，无论是对生物体代谢必需的（如 Cu、Zn、Cr、Fe、Mn）还是非必需的（如 Al、As、Cd、Ni、Pb、Hg），都自然存在于海洋环境中，并且由于人类活动的存在，它们的丰度可能会增加。在本研究中，鱼类被用作生物指示剂，以确定肌肉和鳃组织中金属的生物积累与鱼类健康状况之间的相关性。研究区域是位于意大利西北部的蒂格利奥湾（Gulf of Tigullio），该地区受到多种金属污染来源的影响。组织病理学是研究鱼类生理学主要器官之一的鳃部可能发生变化的重要工具。研究结果强调了某些金属（如 Pb、Ni）与鳃部变化（如上皮细胞增生、上皮细胞隆起）之间的一些相关性，为不同鱼类物种提供了基线数据，可在进一步的研究中用于比较目的。
