A multidisciplinary study was conducted on water from two rivers in the Abruzzo region of Italy. The study highlighted the importance of histopathological investigations in the evaluation of the environmental impact on fish. Brown trout (Salmo trutta fario) from the Aterno river and chub (Leuciscus cephalus) from the Vomano river were sampled in winter and then again in spring. Histopathological investigations of gills, kidneys and livers revealed inflammatory and degenerative lesions, early warning signals of environmental stress. Lesions were evaluated semi-quantitatively and findings were ranked. The histopathological features were compared with results obtained from the analysis of water samples and macroinvertebrates collected in the two rivers (extended biotic index). All results confirmed alterations of the environment.
对意大利阿布鲁佐地区两条河流的水进行了一项多学科研究。该研究强调了组织病理学调查在评估对鱼类的环境影响方面的重要性。冬季从阿泰尔诺河采集褐鳟（Salmo trutta fario），从沃马诺河采集雅罗鱼（Leuciscus cephalus），然后在春季再次采样。对鳃、肾脏和肝脏进行组织病理学调查，发现了炎症和退行性病变，这是环境压力的早期预警信号。对病变进行半定量评估并对结果进行排名。将组织病理学特征与两条河流中采集的水样和大型无脊椎动物分析结果（扩展生物指数）进行比较。所有结果均证实了环境的改变。
