The concentrations of nine heavy metals (Cr, Cd, Pb, Ni, Cu, Zn, Mn, As and Fe) in the muscle tissue of four fish species (Oreochromis niloticus, Clarias gariepinus, Poecilia latipinna and Aphanius dispar dispar) collected from Wadi Hanifah were detected in two different seasons. The concentrations of the studied heavy metals, except for Cd, Pb, Ni and Cu in A. d. dispar and P. latipinna, were found to be below the safe limits recommended by various authorities and thus provide an indication of the extent of pollution of these metals. The present study also demonstrates that Zn and Cr were the most and least accumulated metals, respectively, in the studied fish muscle tissues. From the standpoint of human health, this study suggests that there is a possible health risk to consumers due to the current consumption rate of A. d. dispar and P. latipinna in Saudi Arabia.
在两个不同季节检测了从哈尼法河采集的四种鱼类（尼罗罗非鱼、埃及胡子鲶、帆鳍花鳉和阿拉伯溪鳉）肌肉组织中九种重金属（铬、镉、铅、镍、铜、锌、锰、砷和铁）的浓度。除了阿拉伯溪鳉和帆鳍花鳉中的镉、铅、镍和铜外，所研究的重金属浓度均低于各权威机构推荐的安全限值，从而表明了这些金属的污染程度。本研究还表明，在所研究的鱼类肌肉组织中，锌和铬分别是积累最多和最少的金属。从人类健康的角度来看，这项研究表明，由于沙特阿拉伯目前对阿拉伯溪鳉和帆鳍花鳉的消费率，消费者可能面临健康风险。
