Heavy metal pollution of aquatic ecosystems is worldwide problem with consequences on the aquatic organisms. The concentrations of selected heavy metals (Fe, Mn, Zn, Cu, Cd and Pb) were determined in liver, kidney, gills, muscle and bone of barbel (Barbus rebeli) and chub (Squalius squalius) from the river Crn Drim in Macedonia. In general, liver and kidney in both fish species contained the highest concentration of the investigated metals, while muscle showed lowest bioaccumulation of heavy metals. Analyses supported significant seasonal differences in some organs for some metals: highest value in spring-summer compared to autumn-winter period. Generally, metal concentration was higher in the barbel than chub. The concentration of metals in muscle are bellow permissible value and do not constitute any threat for human health due to the consumption of metal loaded fish.
水生生态系统的重金属污染是一个全球性问题，会对水生生物产生影响。测定了马其顿Crn Drim河中的髯鲤（Barbus rebeli）和雅罗鱼（Squalius squalius）的肝脏、肾脏、鳃、肌肉和骨骼中选定重金属（铁、锰、锌、铜、镉和铅）的浓度。总体而言，两种鱼类的肝脏和肾脏中所含被调查金属的浓度最高，而肌肉中重金属的生物累积量最低。分析表明，某些金属在某些器官中存在显著的季节差异：与秋冬季节相比，春夏季节的值最高。一般来说，髯鲤体内的金属浓度高于雅罗鱼。肌肉中的金属浓度低于允许值，食用受金属污染的鱼类不会对人体健康构成任何威胁。
