The content of the potentially toxic elements, iron and manganese, in the grapevine cv Tamjanika growing near the biggest copper mining/metallurgical complex on the Balkan peninsula: phytoremediation, biomonitoring, and some toxicological aspects
Plants growing in areas polluted by heavy metals represent excellent models for the investigations related to their potentials for hazardous metals accumulation which further may help in the estimation of plant practical biomonitoring and phytoremediation potentials. In this study, the potentials of the grapevine cultivar Tamjanika from a highly polluted region in Eastern Serbia, with intensive copper mining and metallurgical activities, were estimated in regard to the potentially toxic elements such as iron and manganese; the potential danger from these metals through fruit consummation is also considered. Used methods were the following: ICP-OES analysis, calculation of biological coefficients, the Pearson correlation study, one-way ANOVA, and hierarchical cluster analysis. The results revealed that a great majority of the recorded concentrations in different plant organs were in the range of normal concentrations, as well as that the calculated accumulation rates for both metals were very low. The data also pointed to generally minimal to moderate enrichment by these metals which represents totally dissimilar situation in comparison with other heavy metals detected in the very same plant samples. The results of this study suggested that the investigated plants of the grapevine cv Tamjanika assimilated iron and manganese predominately according to their individual needs, and confirmed that the utilization of this plant species can be very effective in different biomonitoring procedures and also in the phytoremediation procedure known as phytostabilization. At the same time, it was obvious that even in aggressive circumstances its fruit was protected from some serious contamination and kept pretty safe for consummation.
