COMPILING PROGNOSTIC MAPS OF FLUORIDE CONTAMINATION RISK OF SOILS (BY EXAMPLE OF MOSCOW OBLAST)

摘要

The experience of compiling prognostic maps of the ecological risk of fluoride contamination of soils is examined. The results of experimental studies of the dependence of the fluorine-fixing ability of soils on the soil-particle distribution and acidity can be used to group them according to this ability. The degree of the increase in the availability of organomineral components of soils under the influence of sodium fluoride increases with the decrease in the stability of humus binding in soil, which is used to group soils according to their resistance to the effect of alkaline fluorides.
