- Abstract
According to field surveys of arable soils in the zone of anthropogenic emissions of the cryolite plant, the levels of soil contamination with fluorine, depending on the distance to the source, were determined and the correlation of agrochemical soil indicators with the content of fluorine in them was identified. Soil 20 km away from cryolite plant, can be considered clean (fluoride content of 2.6 mg/kg). Evaluation of the productivity of plants at the sampling points demonstrated that the content of water-soluble fluorine in the soil above the MPC leads to a decrease in crop yields. In micro plot and small experiments, the effect of fluorine pollution on the productivity of plants was studied, the protective shields from fluoride contamination were tested. It was found that enhanced mineral nutrition contributes to the active plants resistance to oppression caused by fluoride pollution. Breakdowns in the anatomical structure and formation of generative cells under the influence of toxic effects of fluorine were revealed. The nature of chromosomal rearrangements after fluoride pollution resembles the effect of physical and chemical mutagens on plants.
