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.

Chemometric evaluation of trace metals in Prunus persica L. Batech and Malus domestica from Minicevo (Serbia).

The samples of spatial soils and different organs of Prunus persica L. Batech and Malus domestica were analyzed by methods such as inductively coupled plasma optical emission spectroscopy (ICP-OES), Hierarchical Cluster Analysis (HCA), One-way ANOVA, and calculation of biological accumulation factors (BAFs) with the aim of investigating whether these methods may help in the evaluation of trace metals in plants, as well as in the estimation of plant bioaccumulation potentials. ICP-OES provided accurate data on present concentrations of Cu, Zn, Pb, As, Cd, and Ni which showed that most concentrations were in normal ranges, except in some cases for Cu, Zn, and As. HCA illustrated nicely various specifics in the distribution of metals in both investigated systems plant-soil. One-way ANOVA pointed successfully on the existing statistical differences between metal concentrations. Calculated BAFs showed that both plants had very low accumulation rates for all elements; they acted as metal excluders.

Plant parts of the apple tree (Malus spp.) as possible indicators of heavy metal pollution.

The content of Cu, Zn, Pb, As, Cd, and Ni was determined by ICP-OES in spatial soil and parts (root, branches, leaves, and fruit) of the apple tree (Malus spp.) from polluted sites near The Mining and Smelting Complex Bor (Serbia). The aim of this study was to examine if the obtained results can be used for biomonitoring purposes. Data recorded in plant parts, especially leaves, gave very useful information about the environmental state of the Bor region. Conveniently, these data described well the capability of investigated plant species to assimilate and tolerate severely high concentrations of heavy metals in its tissues, which may further allow the possibility for utilization of the apple tree for phytostabilization.

Assessment of the quality of polluted areas based on the content of heavy metals in different organs of the grapevine (Vitis vinifera) cv Tamjanika.

In this study, the samples of the spatial soil and organs of the grapevine (Vitis vinifera) cultivar Tamjanika were collected from the selected zones near the Mining and Smelting Complex Bor (East Serbia). They were analyzed by ICP-OES to determine the content of Cu, Zn, Pb, As, Cd, and Ni with the aim of ascertaining if these data may help in the assessment and improvement of the quality of environment in polluted areas such as Bor and its surrounding area. The results obtained from the calculated biological and enrichment factors, as well as from the Pearson correlation study and hierarchical cluster analysis confirmed that very useful information is recorded in plant organs: root, stem, leaves, and fruit. Yet, when the atmospheric pollution is the sphere of interest, the most informative data are found in unwashed leaves. The results of this study indicated also that the investigated plant species has some highly effective strategies involved in tolerance to the stress induced by heavy metals, which makes it an excellent candidate for phytostabilization purposes. Planting of this grapevine cultivar can be recommended in all areas that are severely polluted with heavy metals.

Influence of pyrometallurgical copper production on the environment.

In this paper the influence of pyrometallurgical treatment of copper sulphide minerals and pyrite on the environment from the aspect of ambient air pollutions is considered. Results of emission of SO(2) and particulate matter from the location with the most pollution are presented. According to the results it could be seen that the Bor's citizen were exposed to the high concentration of SO(2) and arsenic which were found to be multiple over the Serbian legislative limits during 2007. Also, the reasons and consequences of this pollution were analysed.
