The aim of this study was to determine dehydrogenases activity in the soil with the addition of NaCl in different concentrations and to identify whether the observed changes to be considered dangerous, tolerated, or insignificant for soil ecosystem. The study was carried out on samples of loamy sand, sandy loam and sandy clay loam. The aqueous NaCl solutions were introduced to soil in the doses of: 0; 0.05; 0.50; 5.00; 50.00 mmol > kg–1. Dehydrogenases activity was measured spectrophotometrically in 1, 3, 7, 14, 28, 56 and 112 day of incubation. The results are indicated in the graphs of ecological hazard zones (Domsch et al. 1983). The presence in soil of sodium chloride caused inhibition of dehydrogenases activity. The observed inhibition level of these enzymes was greatest in loamy sand and decreased with organic carbon and clay fraction C 0.002 mm. Soil salinity with largest doses of NaCl (5.00 and 50.00 mmol > kg–1), in relation to ecological significance of soil contamination could turn into its degradation.
