“…Therefore, this anthropogenic influence exceeds permissible value of heavy metal content in soils caused major disruptions to their quality. The analysis of other authors of biochemical properties of the species from different polluted areas of Suceava County showed that the range of antioxidant responses to the pollution conditions at Tarnita and other sites was different, depending on the type of pollutant interference in the environment [9]. Thus, the metal ions resulting from polymetallic sulfide alteration in Tarnita were able to inhibit the activity of SOD in Picea abies L.…”

Heavy metals are destructive environmental stressors that greatly reduce plant growth and productivity. Here, the content of some heavy metals (Fe, Cu, Zn and Mn) and mineral nutrients (Ca, Mg and K) in silver fir (Abies alba Mill.) and European beech (Fagus sylvatica L.) wood from two sites in the Tarni�a mining area (North-Est Romania) was analyzed. The first site (no. 1) is located near a big tailings dump, whereas the other one (no. 2) is situated 6 km South, in a less polluted area. The purpose of this work was to evaluate the present-date levels of such elements in the investigated biological materials and to compare them. Measurements of heavy metal content in wood were performed with an AAS flame spectrometer, whereas an ICP-OES spectrometer was used for soil and tailings dump samples. The Mn content was higher in the site no. 1 located near the dump, for both species, but the difference was statistically significant only for the European beech trees. The Zn content of samples from the site no. 1 was lower than that corresponding to the second one (no. 2) for both species, but significant for the silver fir only. However, there was not found a significant difference in respect to both iron and copper in the samples collected from the two species and two different sites. Furthermore, the content of Ca and Mg of both species was found higher for the site no. 2, suggesting a better state of nutrition of the investigated trees than of those located near the tailings dump. The content of calcium and magnesium of silver fir was negatively correlated with the diameter of the trees collected from both sites.

“…Environmental pollution with heavy metals around the barite closed mine of Tarniþa does represent high risks to the public health in Eastern Carpathians, being also an intensively studied issue [6][7][8][9][10][11][12]. There are also some other similarly contaminated areas in Romania such as Copºa Micã, Baia Mare and Zlatna [13][14][15][16][17].…”
