Trace elemental analysis, besides its ability to determine stable isotopes ratios, represents a possible complementary tool useful to differentiate wines based on their regional origins. Wines and their provenance soils from two major wine producing areas in Southeast Romania ('Valea Calugareasca' and 'Murfatlar'), and also wine from the region of Moldova (Eastern Romania) were analyzed by inductively coupled plasma mass spectrometry (ICP-MS), and statistical data of elemental composition was used to differentiate these wines according to grape type and geographical origin. Moreover, this study gathers relevant elemental trace composition of wines produced in most important Romanian vineyards, thus offering a useful wine differentiation tool by their production district. The results show that the differentiation of Romanian wines according to their provenance is based on the following main elements: Ni, Ag, Cr, Sr, Zn, and Cu for Valea Calugareasca, Rb, Zn, and Mn for Murfatlar, and Pb, Co, and V for Moldova. © 2012 Elsevier Ltd.

Fishery and aqua culture is an important segment of activity in the south-eastern area of Romania. This fact is already related to the nuclear activities on the both sides of the Danube river and every new contribution to accomplish the database is welcomed. This independent surveillance exercise is based on the unique set of services offered by LRPM at IFLN-HH. Magurele to measure tritium as tritiated water, one of the most important nuclear radioactive effluents. The results obtained from April to October 2009 demonstrate that there is a measurable difference between the areas, even for the low level range of radioactivity, depending on the type and distance from de nuclear objectives. All values are placed well below the maximum permitted by applicable law and demonstrate that nuclear activities were conducted without incident during the research period (April-September 2009).

Trans-resveratrol (3,5,4'-trihydroxy-trans-stilbene) is naturally present in the skin of grapes and therefore is expected to occur in grape products. Recently, there has been a renewal of interest in wine as medical treatment for various disorders. In this study, berry skins of five red grape varieties were analysed at weekly intervals for trans-resveratrol production, during 2012 and 2013 harvest. The obtained wines were also evaluated. Quantifi- cation of trans-resveratrol in grape skin extracts and wines was carried out by high-performance liquid chromatography. Favourable viticultural climate during harvest in 2012 resulted in a higher content of trans-resveratrol. The highest trans-resveratrol content was in Pinot Noir and Feteasca Neagra grape varieties, both in berry skins and wines, while the lowest amounts were identified in Cabernet Sauvignon variety. We can conclude that there was a significant correlation between the content of trans-resveratrol in grape skins and that in the respective wine.

At the Research Station for Viticulture and Enology Murfatlar, beginning with the 2006 was registered a surfaces in conversion - 34 ha of vine planted with Columna variety - designed for to obtain white quality wines and Feteasca neagra variety, an autochthon, ancient vine variety designed for to obtain red high quality wines. The surface in conversion is tucked in observation by I.C.E.A. - an international organisation for certification of the quality 'BIO' (Reg. CEE 2092/91). The climatic conditions of the years 2006-2008 were different face of those from the registered data of the last 40 years, the known dryness present in each summer in this vineyard being in this period excessive. This climate stopped the evolution of the cryptogammic diseases (manna, botrytis) but determining the development of the main pest of vineyard - the grape moth. The management of the weeds was simplified, using the manual works for removing. The quality of the grapes obtained in the BIO-breeding system in the climatic condition of the Murfatlar vineyard was analysed.
