The method of dynamic factors in bioindication and phytoremediation

Abstract

Bioindication and phytoremediation are applied aspects of the accumulation of chemical elements in plants. The fields of bioindication and phytoremediation have required evaluating the processes of the absorption of chemical elements by plants, in order to be able to compare plants by their capacity to absorb chemical elements and to compare the chemical elements by their possibilities to get into plants. However, besides the biochemical viewpoint towards getting of chemical elements into plants, the biogeochemical attitude is also of great importance. The latter is concentrated on the link between a plant and its environment, firstly the soil. In order to compare the changes in the process of uptake of chemical elements by different plants (by evaluating the geochemical changes in the area), to evaluate the influence of soil modification on chemical elements’ participation in the plants’ metabolism, and to provide a quantitative evaluation of the phytoremediation efficiency during a specific period of time, a quantitative method of evaluation is presented in this paper; the method is based on the dynamic factors of bioaccumulation, biophilicity, translocation, and phytoremediation.
