Study on the presence of toxic substances in waters from disaffected industrial areas

Abstract

The paper presents aspects regarding the water quality coming from drillings carried out in disused industrial areas, from the Brăila - Galați area. The studied parameters include the analysis of salts such as sulfates, nitrates, phosphates and
carbonates and the analysis of toxic compounds such as phenols, copper, lead, iron and aluminium. The experiments revealed the presence of some of the studied toxic substances. Finally, the results obtained and the classification of the studied indicators within the admissible limits were discussed and potential methods and techniques for depollution of drilling waters and soil in derelict industrial areas were proposed.
