Sediment constitutes an interesting and valuable material for observation of human impact on the environment. Based on the sediment core samples in two Tatra Mountains lakes, determination of the selected elements (including cesium 137 radionuclide activity and heavy metals' concentrations) and dating of the obtained layers by the lead 210 method, chemometric analysis of the resulting data set was done. It was established, as a result of Cluster Analysis, that the variability of the determined parameters was distinct in the lakes with much higher concentrations of heavy metals in Smreczyński staw lake. Also, the influence of human activity (long distance transport of contaminants) is notable on the north slopes of the Tatras (Smreczyński staw lake) comparing to Popradske pleso lake. The examined elements can be divided into two groups –natural to the site origin (iron, manganese, and magnesium), and elements whose accumulation in the sediments can be related (at least in part) to human activity (¹³⁷Cs, zinc, copper, cadmium, lead, and chromium). The results confirm the existence of the so called “screen effect”, meaning that the Tatra Mountains’ crest delimits to a considerable extent further transport of pollutants to the south side of the Tatra Mountains slopes.

沉积物是观察人类对环境影响的有趣且有价值的材料。根据两个塔特拉山湖泊的沉积物岩心样品，通过铅210法确定所选元素（包括铯137放射性核素活度和重金属的浓度）并确定所获得层的年代，并对所得数据集进行化学计量分析。通过聚类分析，可以确定所确定参数的变异性在Smreczyński秸秆湖中重金属浓度高得多的湖泊中是不同的。此外，与波普拉德斯克普莱索湖相比，人类活动（污染物的长距离运输）的影响在塔特拉山（Smreczyński斯托湖）的北坡上尤为明显。¹³⁷ Cs，锌，铜，镉，铅和铬）。结果证实了所谓的“屏蔽效应”的存在，这意味着塔特拉山的山顶在很大程度上限制了污染物向塔特拉山斜坡南侧的进一步输送。
