Investigation of genotoxicity in river sediments

Investigation of genotoxicity in river sediments AbstractThe purpose of the present study was to develop a useful screening method to assess genotoxic effect of polluted bottom sediments from the water reservoir Ružin No.I. The Hornád and Hnilec Rivers drained a former mining area, have been polluted in the long-term by heavy metals (Cu, As, Sb, Hg), which significantly contributed to environmental degradation. Genotoxicity of bottom sediment was evaluated by test SOS-ChromoPadTM 3.0 for solid samples without extraction. The mentioned test represents simple, quick and direct sediment phase toxicity testing procedure. In this test bacterial strain Escherichia coli K12 PQ37 was used. The results of SOS-ChromoPadTM 3.0 showed that sample Hornád has low potential genotoxic effect on the environment. It was determined on the basis of slight blue colouration of chromogenic paper at the point of sediment application. The sample Hnilec was negative. This test allows significantly reduce the time for obtaining information about sediments genotoxicity and accept necessary security proceeding in time. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nova Biotechnologica et Chimica de Gruyter

Abstract

AbstractThe purpose of the present study was to develop a useful screening method to assess genotoxic effect of polluted bottom sediments from the water reservoir Ružin No.I. The Hornád and Hnilec Rivers drained a former mining area, have been polluted in the long-term by heavy metals (Cu, As, Sb, Hg), which significantly contributed to environmental degradation. Genotoxicity of bottom sediment was evaluated by test SOS-ChromoPadTM 3.0 for solid samples without extraction. The mentioned test represents simple, quick and direct sediment phase toxicity testing procedure. In this test bacterial strain Escherichia coli K12 PQ37 was used. The results of SOS-ChromoPadTM 3.0 showed that sample Hornád has low potential genotoxic effect on the environment. It was determined on the basis of slight blue colouration of chromogenic paper at the point of sediment application. The sample Hnilec was negative. This test allows significantly reduce the time for obtaining information about sediments genotoxicity and accept necessary security proceeding in time.
