Abstract

: This paper is focused on evaluating the quality of bottom sediments and water in the watershed of the Delˇna creek, where gold, antimony and mercury were mined in the past. The results showed that the biggest source of pollution was a heap of mining material, where the limit values of Sb, As, Hg and Pb concentrations in the sediments were exceeded. Other sources of pollution in the river basin were the right-hand tributaries. A comparison of the dependencies of the concentrations of potentially toxic metals in the water and sediments shows that while the concentrations of pollutants in the waters react to the current state of water quality in the basin and tributaries (pH
人类活动对德伦纳河流域底泥质量的影响
:本文的重点是评估德尔纳溪流域底层沉积物和水的质量,该流域过去曾开采过金、锑和汞。结果表明,最大的污染源是采矿材料堆,沉积物中的锑、砷、汞和铅浓度都超过了限值。流域内的其他污染源是右侧支流。对水体和沉积物中潜在有毒金属浓度的相关性进行比较后发现,水体中污染物的浓度与流域和支流目前的水质状况(pH 值、氨氮、砷、汞和铅)密切相关。
