We have presented a study to determine the possibility for the usage of Cladophora fracta as bioaccumulator of the metals (Au) and silver (Ag) both have characteristics of pollutant and precious in mine water. The highest concentrations accumulated by C. fracta were determined as 5.8 ± 0.3 and 5323 ± 75 µg/kg for Au and Ag, respectively. The results showed that the accumulation of the metals measured followed the order of Ag > Au. The Metal Pollution Index (MPI) values calculated between 39.37 × 10 and 175.7 × 10 were used to determine the pollution degree of C. fracta. As a result, it was determined that C. fracta highly accumulated the precious metals from the gallery water. Therefore, C. fracta was a good bioaccumulator for the remediation of Au and Ag in mine gallery waters. In this way, it is possible to minimize or eliminate the environmental risks of the precious metals in the gallery waters.
我们进行了一项研究，以确定石莼是否可以作为矿区水中具有污染物和贵金属双重特性的金（Au）和银（Ag）的生物蓄积体。C. fracta 积累的最高浓度分别为 5.8±0.3 和 5323±75μg/kg。结果表明，金属的积累量按 Ag>Au 的顺序排列。计算得出的金属污染指数（MPI）值在 39.37×10 和 175.7×10 之间，用于确定 C. fracta 的污染程度。结果表明，C. fracta 从矿坑水中高度积累了贵金属。因此，C. fracta 是修复矿坑水中 Au 和 Ag 的良好生物蓄积体。通过这种方式，可以最小化或消除矿坑水中贵金属的环境风险。
