Effects Of Road Deicing Salts On Soil Microorganisms

Popis výsledku v původním jazyce

The use of road deicing salts in winter was many times reported to result in negative effects on surrounding terrestrial ecosystems. In our study, effects of deicing salts (mostly NaCl) on soil properties were evaluated and risk for soil microorganisms was assessed by two different approaches: 1) soil microbial biomass and its respiration activity was measured, 2) soil extract toxicity was tested in bacterial tests. Three similar mountain forest stands were chosen along the contour road and soil was sampled on the slope above the road (control) and 1m, 10m, and 30m below the road (along the runoff). Overall salinization was recorded as main effect on soil properties: Na+ concentrations increased toward the road up to 100mg/L; soil pH(water) was increased below the road with maximum pH 8 in 1m distance; exchange pH was near zero nearby the road; base saturation steeply increased to 100% toward the road.
