Abstract

Cartilaginous fish species have ecological importance. Besides, the ecotoxicological studies on these species are pretty insufficient. In this study, Al, Cr, Mn, Fe, Cu, Zn, As, Pb, Cd, and Sr levels were determined in muscle, liver, gill, kidney, spleen, stomach, and gonad tissues of Alopias superciliosus (Female, 240 cm TL) caught from Mersin Bay. Tissue metal analysis was determined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). A statistical difference was found among the tissues in terms of the metals. Fe was determined to be the highest level in all tissues (pGill>Spleen>Gonad>Kidney>Stomach>Muscle. Zn was detected at higher levels in the liver and stomach and As in other tissues after Fe. Al has the highest level after Zn and As and was mainly found in the gills. The tissue Cu and Zn levels were found in the same order from highest to lowest as Liver>Gonad>Kidney>Spleen≥ Stomach>Gill>Muscle. Sr was higher in the stomach, gonad, and kidney than in the other tissues. Cd levels were found in higher than Pb levels in the examined tissues. Liver Cd level was determined as 57.37 µg g-1 dw. Except for the liver, Mn levels were found low than Cr levels in the examined tissues. The distinction between the tissue levels of the investigated elements has changed depending on the functional differences between the tissues and metal metabolisms.

1841年地中海大眼长尾鲨Alopias superciliosus Lowe的元素组成首次报告

软骨鱼类具有重要的生态意义。此外，对这些物种的生态毒理学研究也相当不足。本研究对采自美尔新湾240 cm TL雌毛毛斑鹭(Alopias superciliosus)肌肉、肝脏、鳃、肾脏、脾脏、胃和性腺组织中的Al、Cr、Mn、Fe、Cu、Zn、As、Pb、Cd和Sr含量进行了测定。组织金属分析采用电感耦合等离子体质谱法(ICP-MS)测定。在这些组织中发现了金属含量的统计差异。各组织中铁含量最高(鳃>脾脏>性腺>肾脏>胃>肌肉)。肝脏和胃中锌含量高于铁，其他组织中砷含量高于铁。Al的含量仅次于Zn和As，主要存在于鳃中。组织Cu、Zn水平由高到低依次为肝脏>性腺>肾脏>脾脏≥胃>鳃>肌肉。Sr在胃、性腺和肾脏中的含量高于其他组织。在被检查的组织中发现Cd水平高于Pb水平。肝脏Cd水平为57.37µg g-1 dw。除肝脏外，在检查的组织中发现锰水平低于铬水平。所研究元素的组织水平之间的区别已经改变取决于组织和金属代谢之间的功能差异。
