This study aimed at evaluating various fruit samples using atomic absorption spectrometry method, the content in mineral elements, macroelements (Na, K, Ca, Mg) and microelements (Cr, Cu, Mn, Fe, Cd , Pb, Zn, Co and Ni). Fruit samples were taken from supermarkets (imported products) and agricultural markets (domestic products) in the city of Timisoara, Romania. The results obtained by chemical analysis were evaluated statistically based on method of main components analyzed. Major influence in the group had evidence if macroelements potassium and sodium, iron and manganese where microelements. The results were compared with results obtained by other researchers in the world. The results fall within the legal limits set by law.

Cultivation of oat in the limiting areas of tailings pond might be regarded as one of the possibilities that could lead to the general amelioration of these places. In order to characterize the waste products, to determine and evaluate the components that may be leached from waste products and that can affect the limiting areas of tailings pond, leaching tests were performed. In this paper, we have observed the influence of eluate, obtained from leaching tests, on seed germination, radicle and coleoptyle development as well as on the amount of accumulated dry matter for Avena sativa L., genotypes. According to our researches, we may conclude that the studied genotypes of Avena sativa L. showed tolerance to eluate while values registered for seed germination, radicle and coleoptyle development as well as dry matter content were comparatively higher than those registered for the control variant.
