Six white wines from Blaj vineyard obtained from clone and new created varieties of grapes, have been studied. Their volatile compounds, free amino acids, free fatty acids, content in polyphenols and flavonoid, antioxidant and antityrosinasic activity were compared. The results showed few differences among the analyzed wines. The volatile extracts of wines gave very similar compounds. The major compounds were phenylethyl alcohol. All the white wines of Blaj contained a large amounts of proline in comparison with the other amino acids and important essential amino acids. The fatty acids were found in very small quantities. Antioxidant activity and total content in polyphenols of wines showed that Muscat Ottonel have a very high antioxidant potential comparable with some red wines. The content in flavonoids is small in all white wines. Antityrosinasic activity of studied wine proved to be high to Blasius and Muscat Ottonel wine. The GC-MS method proved to be an excelent method for wine characterization.

Mineralogical and chemical characterization of soils is important in for the use of soils as agricultural land. The soil from downstream Bârzava River was characterized and existing geological features of this soil were presented and correlate with the size surfaces. pH measurements of soils samples collected from three different locations and from two different depths were performed. The soil samples were also analysed in order to assess the major and trace elements content. It is known that the pH and heavy metal concentrations are vital factors for plant growth and the obtained results could be use in future for elaboration of some soil bioremediation techniques.
