Abstract

The gravel pits in the area of Bratislava arose after the Second World War, because of use of large amounts of gravel for building purposes. Water in gravel pits originates in infiltrated Danube water, rainfall water and inflows from Malé Karpaty Mts. At present, gravel pits are used for recreational purposes, water sports and for fishing. The aim of the paper is to estimate and evaluate the oxygen regime of the gravel pits water in the area of Bratislava. Oxygen regime was evaluated using limits of Slovak Technical Standard STN 75 7221, Quality of water, Classification of surface waters. Chemical analyses of the period 2000–2005 were used as the input data.

Key words: gravel pits, surface water, oxygen regime, water quality
