Effects of road deicing salts on soil microorganisms
in this study, the effects of road salting on the quality of forest soils near the road were monitored in the Krkonoše Mountains (Czech republic). Physical, chemical properties and microbial parameters of soils were determined and the toxic potentials of soil water extracts were evaluated using the bacterial tests (Microtox and Pseudomonas putida growth inhibition test). increased concentration...
متن کاملEffects of soil treatments on the survival of soil microorganisms.
In biological control studies of plant-parasitic nematodes in field soil improved methods are needed for reducing or eliminating specific soil inhabiting microorganisms. Microwave heating of soil decreases soilborne fungi and bacteria, but not Pasteuria spp. Bacterial and fungal colony forming units were reduced to nondetectable levels in microwaved heated field soft (650 watts) at 5.2% moistur...
متن کاملPotential for local adaptation in response to an anthropogenic agent of selection: effects of road deicing salts on amphibian embryonic survival and development
The application of millions of tons of road deicing salts every winter in North America presents significant survival challenges to amphibians inhabiting roadside habitats. While much is known of the effects of NaCl on anuran tadpoles, less is known of effects on amphibian eggs, or any caudate life stage. In addition, little is known of the effects of MgCl2, which is now the 2nd most commonly u...
متن کاملEffects of elevated atmospheric CO2 concentrations on soil microorganisms.
Effects of elevated CO(2) on soil microorganisms are known to be mediated by various interactions with plants, for which such effects are relatively poorly documented. In this review, we summarize and synthesize results from studies assessing impacts of elevated CO(2) on soil ecosystems, focusing primarily on plants and a variety the of microbial processes. The processes considered include chan...
متن کاملAre Deicing Salts Necessary to Promote Scaling in Concrete?
The main purpose of the present study is to investigate the role of the material parameters such as permeability, thermal diffusivity, and pore size distribution on the mechanical behavior of cementitious structures submitted to frost action, such as surface scaling. An experimental device, in which a cement paste specimen is exposed to freezing-thawing cycles under a thermal gradient, has been...
