Using potentilla bifurca l. As a possible indicator of pollution in industrial regions

Kanibolotskaya Yu. M.

Due to the significant impact of anthropogenic factors on the environment in man-made regions, Potentilla bifurca L. is considered as an indicator of pollution of industrial areas by some heavy metals (Ti, Mn, Cr, Fe, Ni, Cu, Zn, Pb and Sr). Their content in plant (P. bifurca) and soil samples selected in the suburbs of Pavlodar and Aksu (Pavlodar region, Kazakhstan) at various distances from existing industrial enterprises was analyzed; geobotanical studies have also been carried out. It was found that Zn and Cr accumulate in P. bifurca more actively than Sr and Mn, and Ni, Pb, Cu, Ti, Fe - in rather small quantities. There is no obvious negative effect on Potentilla bifurca of high concentrations of these metals. In this regard, Potentilla bifurca's accumulation capacity, for example, Zn and Cr, can be used (taking into account various factors) to determine the presence of environmental pollution in man-made regions, in particular in areas where metallurgical plants are located.
