Abstract

The utilization of fish bioindicators has become of crucial importance for ecosystem contamination assessment. Bleak (Alburnus alburnus) is a widely distributed epipelagic fish species characterized as very active with fast metabolism which can lead to a high accumulation of pollutants in tissues. Bleak is easy to sample, identify in the field by morphological characteristics, and easy to work within the laboratory. This study deals with the bleak sensitivity in detecting the pressure of the potentially toxic elements (PTEs) in the large lowland Great Morava River. The Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sn, and Zn were estimated in whole body composite (wbc) of bleak. The study was conducted at Great Morava River, near the city of Paraćin in Serbia. The highest concentrations of essential elements Zn and Fe were detected. The most toxic elements As and Hg were below detection limits. The metal pollution index (MPI) was 0.39. In large lowland rivers, point sources of pollution such as municipal wastewaters of smaller settlements usually have only local impact due to high dilution by the main watercourse. Since bleak is a site-specific species, results in this study indicated that this stretch of the Great Morava River is slightly affected by PTEs. None of the elements above the maximum permitted concentrations (MPC) in fish meat for use in the human diet, prescribed by the Official Gazette and European Commission Regulation, were not recorded.
低地大摩拉瓦河中潜在的有毒元素。暗淡的生物指示
鱼类生物指标的利用已成为生态系统污染评价的重要内容。萧伯纳(Alburnus Alburnus)是一种广泛分布的上层鱼类,其特点是代谢非常活跃,代谢速度快,可导致污染物在组织中大量积累。萧伯纳易于取样,在野外通过形态特征进行鉴定,并且易于在实验室内工作。本文研究了大摩拉瓦河大低地潜在有毒元素(pte)压力检测的低灵敏度。估算了白鲸全身复合(wbc)中Al、As、Cd、Co、Cr、Cu、Fe、Hg、Mn、Ni、Pb、Se、Sn和Zn的含量。这项研究是在塞尔维亚Paraćin市附近的大莫拉瓦河进行的。其中必需元素锌和铁含量最高。毒性最大的元素砷和汞均低于检出限。金属污染指数(MPI)为0.39。在大的低地河流中,点源污染,如较小定居点的城市废水,由于主要水道的高度稀释,通常只产生局部影响。由于萧伯纳是一种特定地点的物种,本研究结果表明,大摩拉瓦河的这段河段受pte的影响较小。官方公报和欧盟委员会法规规定的用于人类饮食的鱼肉中超过最大允许浓度(MPC)的元素均未被记录。
