In this paper, the authors aim to realize an in-depth analysis of the current characteristics of the globalization phenomenon from the viewpoint of the European Union and Romanian economy. The study will pursue some of the globalization indicators published by Eurostat, their status and a multidimensional perspective on their evolution. Namely, the foreign trade, the foreign direct investments, the employment, value added shall be subjected to analysis. The authors will apply statistical and econometric techniques to outline the behavior of economic globalization, depending on the values and dynamics of the support indicators. The structural and dynamic evaluation shall consider the main aspect of the multi-dimensional perspective, the geographical dimension. Both statistical and econometric tools applied lead to a set of conclusions, either general or subject-oriented, which show the present impact and trends of globalization in the European Union and Romanian economic activity. The research question was focused on how strong is the influence of globalization indicators on the economic growth for European Union and Romania. The results outline the behavior of the globalization indicators in the recent period, with focus on the effects of the economic crisis. The main indicators considered were the net export, import, export and the foreign direct investments, and their impact of the Gross Domestic Product is also revealed.

People can be exposed to PAs by consuming phytotherapeutic products, food from crops contaminated with seeds of some species with high content of PAs, and/ or contaminated animal products like bee products. For this reason we developed and validated a method for quantitative determination of PAs, from the most frequently contaminated food sources, honey and flour. Colorimetric Ehrlich reagent method was used with standard addition (1mg/kg senecionine). The extraction solvent was methanol 50% acidified with citric acid to pH 2-3, as this solvent can be used for alkaloids and N-oxides. We found that, in extracting the alkaloid only once from the dietary sources, the percent of recovery is low (52.5% for honey, and 45.75% for flour). Using successive extractions, three times with the same solvent, the senecionine retrieval percentage increased to 86.0% for honey and 76.0% for flour. The method was validated using the following parameters: selectivity, linearity (0,25-20 mg/ mL senecionine), accuracy (average recovery 93.5 -107.93%) and precision (RSD 3,26-4.55%.). The calculated limit of quantification (0.174 mg/ mL) makes this method applicable for determining Pas occurring at toxic levels for consumers.
