摘要：Studies of physicochemical properties of polar environment waters were carried out in individual stages of water hydrological circulation in the north-west part of Wedel Jarlsberg Land on Spitsbergen. The aim of the research was estimation of changeability of physicochemical characteristics of waters during the polar summer in the rivers sup- plied from the glacier and from the permafrost. In the period of 15 July ¨C21 August 2005 there were taken up 290 water samples including 15 of precipita- tion, 9 from patches of melting snow, 39 from the gla- ciers Scott and Renard, 132 river samples 31 from streams on tundra, 56 from springs and 8 from small lakes. Time changeability was recorded from every- day observations of water levels and physicochemical analyses of the samples taken up from the river sup- plied from the Scottbreen and Wydrzyca Rivers, its tributaries and the springs draining the unglaciated area. In the water samples there ware signified: sus- pension, pH, electrolytic conductivity, BOD, COD, TOC, SiO 2 ,PO 4 , F, Cl, NO 2 ,SO 4 , Ca, Mg, Na, K, NH 4 , Li, Sr, Fe, Mn, Zn, Cd, Pb, Cu. The analyses were made based on potentiometric, spectrophoto- mertic, available in the Hydrography Department, Maria Curie-Sk.odowska University in Lublin.
