Chemistry of Bottom Sediments from Selected Karst Lakes in the Vicinity of Staszów (Nida Basin)

Abstract

The aim of this study was to reveal the chemical composition of bottom sediments in karst lakes located in the northern part of Połaniec Basin (eastern part of the Nida Basin, vicinity of Staszów municipality). A field investigation was carried out in 2010 on four lakes: Duży Staw, Donica, Dziki Staw and Łajba. The contents of a very wide range of chemical elements were determined, which is a rarity. On the basis of our research, it was found that the analysed lakes differed considerably between each other in spite of their close location. In general, sediments contained fair amounts of organic substances as well as Fe, Al, Ca and Mg due to the type of source rock and soligenic lake water supply. Increased concentrations of V, Cr and Ni might be explained by the weathering of rock material. In turn, higher contents of Zn, Pb, Cu and Co in the bottom sediments from Duży Staw indicated anthropopression. The measurement results obtained in this study will allow a future comparative analysis with bottom sediments from other lakes.

“…At the same time, hydroecological studies of lakes began [POLISHHUK et al 1977]. In 1983 the Shatsk National Nature Park was established, comprehensive monitoring and research of lakes were organised [CHOIŃSKI et al 2012;FESYUK 2020;ILYIN 2002;ILYIN et al 2010;KHOMIK 2013;MOROZOVA 2006;TIMCHENKO et al 1994;ZABOKRYTSKA et al 2006]. It should be noted that the study of Holocene lakes is relevant among scientists from other countries [CHOIŃSKI et al 2016;DAWIDEK et al 2013;GROCHOWSKA et al 2019;VLASOV, SZCZYPEK 2020;WOLANIN et al 2016].…”
