Abstract

Introduction. The operation of the Teghut copper-molybdenum enterprise resulted in the man-made load on the environments in terms of concentrations of some heavy metals (autumn 2016), the migration of which continued even after the plant shutdown (autumn 2018). Methods. The authors studied changes in the concentrations of Mo, Zn, and Cu in samples of Shnogh River water and coastal soils near the tailing storage facility territory. Results. During enterprise operation, in water sampling points 1 and 2, a decrease in the concentrations of these heavy metals after the plant shutdown was noted. According to the analysis of coastal soil samples, in points 1 and 2, after the plant shutdown, the Zn concentration decreased by 75% and the Cu concentration decreased by 84% compared with the analysis of samples during enterprise operation. In samples of coastal soils from sampling points 3 and 4, a concentration reverse was observed. Conclusion. The calculation of the geo-accumulation coefficient for the studied heavy metals in soil sampling points 1 and 2 compared to sampling points 3 and 4 indicates a decrease in the man-made load on the environment, caused by plant operation.

尾矿库周边水域及沿海土壤重金属污染情况

介绍。Teghut铜钼企业的运营造成了一些重金属浓度对环境的人为负荷(2016年秋季)，即使在工厂关闭(2018年秋季)后，重金属的迁移仍在继续。方法。作者研究了Shnogh河水和尾矿储存设施附近沿海土壤样品中Mo、Zn和Cu浓度的变化。结果。在企业运营期间，在1号和2号水样点，注意到工厂关闭后这些重金属浓度有所下降。根据对沿海土壤样品的分析，在第1点和第2点，工厂停工后，Zn浓度比企业运营时的样品分析下降了75%，Cu浓度下降了84%。在采样点3和4的沿海土壤样品中，观察到浓度相反。结论。与3点和4点相比，1点和2点土壤重金属的地质累积系数的计算表明，工厂运行对环境造成的人为负荷有所减少。
