The aim of this study was identifying the mechanism through which granitoid intrusions can release their chemical pollutants into the environment. At the first step, all existing data combined into a GIS database to identify target areas for field observation and sampling. In order to compare element concentrations and determine probable overconcentration and chemical anomalies in studied samples, average element concentration values in rock, soil and herbs, element concentrations in testimonial sample and defined standard element concentrations in potable water were used as normalization and comparison values. The results of study indicate anomalies of the elements, which imply a direct relationship between element anomalies in granitoid bodies and adjacent soil through development of hydrothermal and consequent supergene alteration processes. High and abnormal concentration of heavy and toxic elements cannot be seen in water reservoirs, except for rare overconcentration of As, Se, Cu and Mo in several samples. Lack of element overconcentration in water is most probably due to basic pH and high current velocity of underground water. P. Harmala and E. Gerardiana species were selected to study. Overconcentration of Cu and Se is detected in both studied species comparing with the average chemical composition in herbs, while overconcentration of Mo, As, Pb, Cu, Se and Zn in P. Harmala and Se and Mo in E. Gerardiana can be seen in comparison with the testimonial sample. Overprinting of the highest element concentrations in herbal samples and alteration zones can be seen, which implies indirect and direct effect of chemistry of granitoid intrusions and soil, respectively, in chemical composition of herbal species.
