Climatic conditions from areas where vine is cultivated or intended to be cultivated are essential and important to be acknowledged especially in the context of climatic changes that have taken place during the last 50 years. In this regard, prevention solutions are recommended to be implemented as well as solutions that decrease the damages caused...

The long-term use of copper in viticulture has caused great copper accumulation in vineyard soils, resulting in negative effects on the environment through toxicity to aquatic and soil organisms. The aim of this study was to investigate the copper content in vineyard soils, grapes and wines from Dealu Bujorului, Murfatlar, Tarnave, Iasi and Ştefăne...

The purpose of this study is to know better the concentration of chemical elements in the soil from Dealu Bujorului vineyard. The determination of the ten elements from the soil samples was performed using ICP-MS. The results showed diverse patterns of cadmium, lead, uranium, mercury, arsenic, strontium, cobalt, copper, nickel and chromium, all the...

The results showed diverse patterns of Pb, Cd, Zn, Co, Cu, Ni, Mn, Cr and Sn, in case of Pb in all areas exceeded the M.L.A (average 32.59 mg/kg while M.L.A. = 20 mg/kg), other elements shows high concentration that exceed the M.L.A. for Ferneziu and Săsar area. In the case of plant material also records exceedances of the M.L.A for Ferneziu and Să...

The ICP-MS technique was used to determine elemental composition (Pb, Sr, Cd, Ni, Co, Cu, Ni, Hg, As, Cr and Mn) of wines (Muscat Ottonel, Fetească Albă, Fetească Regală, Fetească Neagră, Merlot and Cabernet Sauvignon) wines produced in 2015, 2016 and 2017 from Bujoru, Smulti and Oancea wine-growing centers from Dealu Bujorului Vineyard. For all te...

The ICP-MS technique was used to determine elemental composition (Pb, Sr, Cd, Ni, Co, Cu, Ni, Hg, As, Cr) of wines (Muscat Ottonel, Fetească Albă, Fetească Regală, Fetească Neagră, Merlot and Cabernet Sauvignon) produced during three consecutive years (2014-2016) in Dealu Bujorului Vineyard. The determination of 206Pb/207Pb, 208Pb/206Pb, 206Pb/207P...

Contamination of vineyard soils with heavy-metals has been a worldwide concern, determination of these elements it is important for the wine industry. The aim of this research was to determine the concentration of different heavy metals (Cd, Pb, U, Hg, As, Sr, Co, Cu, Ni and Cr) from vineyard soil on different depths in an area of vineyard cultivat...

Establishing the geographical origin of wines is an issue of major concern for countries around the world, in order to protect quality of wine in case of false statements regarding their geographical origin.The goal of this research was to assess the potential of elemental composition and isotopic signature of lead (207 Pb/ 206 Pb, 208 Pb/ 206 Pb a...

Daily consumption, wine contributes to the requirements of essential elements, such as Ca, Fe, Mn, Mo, Co, Cr, K, Ni, Se and Zn for humans. However, the presence of significant amount of heavy metal in wine may harm the health of consumers. The present work is aimed at establishing the heavy metal content in red wines from Dealu Bujorului vineyard...

Geographical wine traceability is an important topic in the context of wine authentification. Therefore, many researchers have addressed this subject by developing different methodologies based on multivariate analysis of organic and inorganic parameters and also by isotopic signature. The goal of this research was to assess the potential of elemen...

Wine is a complex matrix, which, besides water, alcohol and sugar contain a great variety of components, organic as well as inorganic. Numerous studies have shown that a moderate consumption of wine, especially red wine, improves health and enhance longevity when it is combined with a balanced diet. Daily consumption of wine in moderate quantities...

Ecoclimatic conditions have a great influence on grapevine growth and development. Favourable conditions (solar radiation, temperature, humidity etc.) are important and have a positive effect on the growth and fruition. Critical conditions have negative influences resulting in low grape production and wine quality. The purpose of this research was...

Geographical origin of wine based on its chemical composition is one of the most challenging issues in relation to wine authenticity. In the last decade, many efforts have been made to identify the potential markers and develop reliable analytical methods to determine the wines authenticity. Among these " fingerprints " , the isotopic rations play...

The main objective of this paper is to present quality and uvologic parameters of two elites clonal 'Muscat Ottonel' 35-21, 'Şarbă 25-45' and two varieties 'Muscat Ottonel', 'Şarbă' for aromatic white wines cultivated in Dealu Bujorului vineyard. The highest weight of a grape was recorded in the 'Şarbă 25-45' (183 g) and the lowest was recorded in...

Wine is considered to be a hydro alcoholic solution with more than 1000 components associated in an extremely complex manner, some of them can pass from grapes in an unchanged state, and some are formed during alcoholic and malolactic fermentation, while others appear due to the reactions between substances in their natural state, or based on the e...

The highest values for the absolute fertility coefficient (Cfa) and relative fertility coefficient (Cfr) were recorded for the 'Fetească regală' variety (54.5±1.00% fertility; 1.60±1.00 absolute coefficient (Cfa) and 0.86±1.00 relative coefficient (Cfr). The results show that 'Bujoru' had the best values regarding the average weight of the grape bu...

The ecoclimatic conditions advantageous for the grapevine growth fall into two categories: indispensable conditions and critical natural conditions. The indispensable conditions have negative influences on the growth and fruition of grapevine, resulting in a decreased production both for quantitative and qualitative respects. The purpose of this pa...

Wine is a food product produced exclusively by partial/total alcoholic fermentation of fresh grapes. From a chemical point of view, wine is a complex mixture consisting of water, sugar, ethanol, amino acids, polyphenolic compounds, anthocyanins, organic/inorganic materials. Viticulture depends on meterorological conditions. The wine industry from R...

Abstract: Wine is a food product produced exclusively by partial/total alcoholic fermentation of fresh grapes. From a chemical point of view, wine is a complex mixture consisting of water, sugar, ethanol, amino acids, polyphenolic compounds, anthocyanins, organic/inorganic materials. Viticulture depends on meterorological conditions. The wine indus...

From the chemical point of view wine is a complex mixture of water, sugar, inorganic and organic materials. There are some factor which influence wine composition: grape varieties, soil type, the climate, type of culture, agrochemical product (fertilizers and pesticides) and the practices used for wine making. These factors are directly involved in...

There are some factors which influence the must and wine composition: grape varieties, soil type, the climate, type of culture, agrochemical products (pesticides and fertilizers) and the practices used for wine making. These factors are directly involved in wine quality and in wine characterization. The aim of this paper is to determine the micro-...

Heavy metals are naturally present in soils, and are predominantly inherited from the soil ̉sparent material but are significantly altered by anthropogenic activity which can pose bothenvironmentals and human health risks. The main soil pollution source is: mine entrances (mine openings) ore processing factories, metallurgical factories. Naturally...

An actual concern in wine production technology is the unwanted presence of heavy metals in both the stum and wine. Besides the quality issues that these heavy metals create in the wine, they also affect the health of wine consumers. Because of this situation it's necessary to improve the knowledge of the negative influence of heavy metals on wine...
