Mining generates large volumes of waste, which, if not regulated, can release toxic metals, causing widespread environmental contamination. This study focused on heavy metal contamination in sediments and amphibians within a mining area at Charcas, San Luis Potosi, Mexico. The results revealed that the Lithobates berlandieri individuals inhabiting an area polluted with industrial waste, high levels of heavy metals and metalloids (As, Cd, Cr, Cu, Hg and Pb) were found in sediments and tissues compared to samples from a reference site. Furthermore, the levels of all metals and metalloids in these frogs were higher in the kidney, liver, and skin. Additionally, it can contribute to the proposed use of non-lethal biomarkers (e.g. skin) for medium and long-term monitoring and regulation at these sites.
采矿产生大量废弃物，若不加以管控，这些废弃物会释放有毒金属，造成广泛的环境污染。本研究聚焦于墨西哥圣路易斯波托西州查尔卡斯一个矿区内沉积物和两栖动物中的重金属污染情况。结果显示，与来自参考地点的样本相比，在受工业废弃物污染地区栖息的贝氏豹蛙个体的沉积物和组织中，发现了高含量的重金属和类金属（砷、镉、铬、铜、汞和铅）。此外，这些青蛙体内所有金属和类金属在肾脏、肝脏和皮肤中的含量更高。此外，这有助于提议使用非致死性生物标志物（如皮肤）对这些地点进行中长期监测和管控。
