This study is focused on the analysis of an accumulation of inorganic elements in muscles, liver and gonad of seven fish species from São Francisco River located in the Paraná state of Brazil. Concentrations of the elements were determined using the SR-TXRF technique. In the muscles of fish species, negative length dependent relationships were observed for chromium and zinc ion absorption. The obtained results showed that accumulated Cr ions values are above the limits defined in the Brazilian legislative norm on food.
本研究聚焦于对巴西巴拉那州圣弗朗西斯科河中七种鱼类的肌肉、肝脏和性腺中无机元素积累情况的分析。使用同步辐射全反射X射线荧光光谱技术（SR-TXRF）测定元素浓度。在鱼类肌肉中，观察到铬和锌离子吸收与体长呈负相关关系。所得结果表明，积累的铬离子值高于巴西食品立法规范中规定的限值。
