The CO2 emission from technogenic fluoride-polluted soils of agroecosystems

The long-term investigations (1996–2002) of the gray forest soils in the agroecosystems of the Lake Baikal basin, including technogenic soils that are fluoride-polluted by emissions of the Irkutsk aluminum (SUAL) plant, revealed the specificity of the seasonal and long-term dynamics of the CO₂ emission. The fluoride pollution is shown to activate the mineralization of soil organic matter and, thus, to increase the gaseous carbon losses.
