Abstract

This study assessed the concentrations of cadmium in the gills, livers and muscles of a commercially important tilapia fish (Sarotherodon melanotheron) from Aby Lagoon in Adiaké, Côte d'Ivoire, between January and December, 2010. The organisms were grouped into two composite samples (juvenile and adult) of five individuals. Levels of cadmium were determined in tissues using Perkin-Elmer (AAnalyst 200) Atomic Absorption Spectrophotometry (AAS) after a digestion method. Fish muscle appeared to have a significantly higher tendency to accumulate cadmium (1.19-5.18 µg/g dw) while gills and livers had minimum concentrations (0.07-1.32 and 0.12-1.25 µg/g dw). This study has revealed that the concentrations of Cd in Sarotherodon melanotheron muscle tissue were above the maximum acceptable concentrations for human consumption, thus precautions need to be taken in order to prevent future contamination.

摘要

本研究评估了2010年1月至12月间，取自科特迪瓦阿迪亚克阿比泻湖的一种具有重要商业价值的罗非鱼（黑罗非鱼）鳃、肝脏和肌肉中的镉浓度。这些生物被分为由五条鱼组成的两个混合样本（幼鱼和成鱼）。采用消化法处理组织样本后，使用珀金埃尔默（AAnalyst 200）原子吸收分光光度计（AAS）测定镉含量。鱼肉似乎具有显著更高的镉蓄积倾向（1.19 - 5.18微克/克干重），而鳃和肝脏中的镉浓度最低（0.07 - 1.32微克/克干重和0.12 - 1.25微克/克干重）。本研究表明，黑罗非鱼肌肉组织中的镉浓度高于人类食用的最大可接受浓度，因此需要采取预防措施以防止未来的污染。
