The land subsidence caused by underground mining results in the transformation of water relations in the Silesian Upland, which is located in southern Poland. Detailed studies were conducted in 25 water bodies formed in subsidence basins located on the Silesian Upland. The purpose of the study was to determine the temporal and spatial variability of electrolytic conductivity of the limnic waters retained in the water bodies studied. As part of field work, 12 specific electrical conductivity measurements were condu...

Situated in the central part of the country, Chott El Jerid is the largest periodic lake in Tunisia. The depression is a flat plain lined with Holocene lacustrine sediments, which mostly developed in the form of alluvia and evaporites. Geochemical properties of sediments were tested using the following methods: FUS-ICP, TD-ICP, INAA, Cold Vapour FIMS. As concerns the basic composition, the following substances were identified (average levels): loss on ignition (LOI) пїЅ 24.27%, SiO2 пїЅ 21.46%, CaO пїЅ 20.54%, Na2...
