The concentrations of some heavy metals (Fe, Zn, Mn, Cu, Mo, Pb, Cd) were measured in river waters, macrozoobenthos, and fish (Kura scrapers) from one of the most developed mining areas in Armenia, the Debed River catchment basin. In order to assess heavy metal contamination and its hydro-ecological and health effects, the macrozoobenthos quantitative and qualitative parameters, geo-accumulation index, and hazard index were determined. Microalgal extraction experiments were conducted to assess the microalgal remediation efficiency for heavy metal removal from mining wastewaters. The results showed that the rivers in many sites were polluted with different heavy metals induced by mining activities, which adversely affected macrozoobenthos growth and caused human health risks in the case of waters used for drinking purposes. However, the river fish, particularly Kura scrapers, were determined to be safe for consumption by the local people, as per the conditions of the evaluated fish ingestion rate. The results have shown that microalgal remediation, particularly with M3456, can be used for the efficient removal ~(62-100%) of certain emerging contaminants (Mn, Pb, Cu, Zn, Cd) from mining wastewater discharged in the Debed catchment basin.
在亚美尼亚最发达的采矿区之一的德贝德河流域，测量了河水、大型底栖动物和鱼类（库拉刮削器）中的一些重金属（铁、锌、锰、铜、钼、铅、镉）的浓度。为了评估重金属污染及其水生态和健康影响，确定了大型底栖动物的定量和定性参数、地质累积指数和危害指数。进行了微藻提取实验，以评估微藻修复从矿山废水中去除重金属的效率。结果表明，由于采矿活动，许多地点的河流受到不同重金属的污染，这对大型底栖动物的生长产生了不利影响，并在用于饮用水的情况下对人类健康构成了风险。然而，根据评估的鱼类摄食率，河鱼，特别是库拉刮削器，被确定为可安全食用。结果表明，微藻修复，特别是使用 M3456，可以有效地去除德贝德流域矿山废水中的某些新兴污染物（锰、铅、铜、锌、镉）（62-100%）。
