Abstract:

In Romania, ponds tailings have expanded and started to be areas of deterioration of the environment and ecological unbalances, with a strong impact on the environment. The purpose of this study was to determine the influence of heavy metal contents of mine tailings on the composition and mineral matter of sea buckthorn fruit harvested from the waste dumps from New Moldova, and modeling econometric data. For the purpose it was useful to analyze the medium level, the variant, and the homogenization degree of the data. The needs for this research area arose because of the uniqueness and to identify the beneficial impact of sea buckthorn economic development of the area, by providing raw material for pharmaceutical industry. Sterile samples were collected at different depths (0-120 cm) and K, Cd, Cr, Ni, Zn, Fe and Mn were determined by atomic absorption spectrophotometry. Mineral elements (K, Mg, Ca, Fe, Mn, Zn and Ni.) of sea buckthorn fruits were determined by atomic absorption spectrophotometry. Taking statistical data was performed using econometric software EViews 7.0. Results show that up to a maximum depth of 20 cm to which roots can reach the sea buckthorn, contents of heavy metals cadmium, chromium, nickel, manganese and zinc were relatively low, these elements are leached relatively easily through layers of sand tailings. The sea buckthorn fruits harvested on dumps tailings showed no danger in terms of food safety. The chemical determinations have confirmed that minerals  accumulates especially in leaves and stems.
