Carbon dioxide emission as affected by the properties of arable soils polluted with fluorides

Adverse changes in the physical and chemical properties of arable gray forest and soddy meadow soils (forest-steppe zone, Lake Baikal region) polluted with fluorides emitted by an aluminum smelter in Irkutsk are shown. The field experiments of the long-term (1997-2005) monitoring and laboratory incu...

Description
Summary:Adverse changes in the physical and chemical properties of arable gray forest and soddy meadow soils (forest-steppe zone, Lake Baikal region) polluted with fluorides emitted by an aluminum smelter in Irkutsk are shown. The field experiments of the long-term (1997-2005) monitoring and laboratory incubation experiments revealed that the CO2 emission from the gray forest soil was higher than from the soddy meadow soil. Its intensity depended on the soil properties and buffering capacity of the soils to fluorides, as well as on the content of water-soluble fluorides and the hydrothermal factors.
