Abstract

This study evaluates the effectiveness of Total Reflection X-ray Fluorescence for multi-element analysis in mussels, focusing on sensitivity, precision, and detection limits. Additionally, it offers a cross-regional comparison of elemental composition in mussels from aquaculture farms in Italy, Spain, and Chile. TXRF, using suspensions of mussel samples, proved effective in detecting minor and trace elements, with recovery rates over 80% for Fe, Cu, Zn, As, and Sr. The research offers a chemical element comparison of and mussels, revealing significant variation based on geographic origin. Correlation matrices demonstrated variable associations between elements, indicating that regional environmental conditions influence bioaccumulation. These findings deepen our understanding of how mussels accumulate elements in different environments. However, further research is needed to develop comprehensive elemental databases and to account for seasonal and temporal variations in mussels' elemental composition. This study may bring insight for food safety and public health monitoring.

摘要

本研究评估了全反射X射线荧光光谱法在贻贝多元素分析中的有效性，重点关注灵敏度、精密度和检测限。此外，还对意大利、西班牙和智利水产养殖场的贻贝元素组成进行了跨区域比较。使用贻贝样品悬浮液的全反射X射线荧光光谱法被证明在检测微量元素方面是有效的，铁、铜、锌、砷和锶的回收率超过80%。该研究对[未提及的两种情况]贻贝进行了化学元素比较，揭示了基于地理来源的显著差异。相关矩阵表明元素之间存在不同的关联，表明区域环境条件会影响生物累积。这些发现加深了我们对贻贝在不同环境中如何积累元素的理解。然而，需要进一步研究以建立全面的元素数据库，并考虑贻贝元素组成的季节性和时间变化。本研究可能为食品安全和公共卫生监测提供见解。
