The presented results reflect the researches carried out over the last decade, having as their object the soil, water, vegetal raw materials, and wines from the Republic of Moldova. The analysis of the possible anthropogenic contamination (NAA method) demonstrated the absence of systematic soil pollution. A total of 30 elements were determined in soil samples and the soil-leaves-fruit transfer factors were calculated. Approximately 3000 samples of local wines have been analysed to determine the residual quantities of pesticides. POPs were not found in any of the wine samples. In most of the examined cases (> 60% of samples), the lack of organic pesticide residues was observed. The migration of phthalates into different solutions from polymeric materials (PVC, rubber) and the influence of the temperature on the extraction rate were investigated. It has been shown that the contamination with phthalate residues occurs predominantly at the stage of grape processing, technological treatment, and storage.

Active Substances

Three types of monofloral honey (rapeseed honey, buckwheat and lavender) from the Republic of Moldova were analyzed. The results of the palynological analysis showed that the samples had a dominant type of pollen (at least 45%). In the case of lavender honey, the pollen of the plant Lavandula angustifolia is present in an average value of 74.83 ± 0.3; in rapeseed honey - Brassica napus and for buckwheat honey -Fagopyrum esculentum in average values as follows: 56.07 ± 0.3 and 68.08 ± 0.2% respectively. The study of the content of biologically active substances showed that buckwheat honey is the richest in polyphenols (9.00 ± 0.11 mg gallic acid / kg) and carotenoids (4.24 ± 0.57 mg βcarotE / kg), and maximum content of flavonoids is in rapeseed honey (4.52 ± 0.28 mg catechin / kg). Thus, the obtained results confirm that the honey from the Republic of Moldova falls within the limits recommended by the international regulation assuming adequate working conditions, handling, collection and storage of honey by beekeepers from the Republic of Moldova.

The correct assessment of the presence of potentially contaminating elements in soil, as well as in fruits cultivated and harvested from the same places has major importance for both the environment and human health. To address this task, in the case of the Republic of Moldova where the fruit production has a significant contribution to the gross domestic product, the mass fractions of 37 elements (Na, Mg, Al, Ca, Si, K, Mn, Fe, Sc, Ti, V, Cr, Co, Ni, Zn, As, Br, Rb, Sr, Zr, Mo, Cd, Sb, Cs, Ba, La, Ce, Nd, Sm, Eu, Tb, Yb, Hf, Ta, W, Th, and U) were determined by instrumental neutron activation analysis in soil collected from four Moldavian orchards. In the case of three types of fruits, grapes, apples, and plums, all of them collected from the same places, only 22 elements (Na, Mg, Cl, K, Ca, Sc, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Rb, Sr, Sb, Cs, Ba, La, Th, and U) were detected. The enrichment factor, contamination factor, geo-accumulation index, as well as pollution load index were calculated to assess the soil contamination. At the same time, the metal uptake from the soil into fruits was estimated by means of transfer factors. Soil samples showed for almost all elements mass fractions closer to the upper continental crust with the exception of a slightly increased content of As, Br, and Sb, but without overpassing the officially defined alarm thresholds. In the case of fruits, the hazard quotients for all elements with the exception of Sb in fruits collected in two orchards were below unity. A subsequent discriminant analysis allowed grouping all fruits according to their type and provenance.

The aim of the study. The purpose of the article is to improve the methodological provisions for the development of medium-term forecast of exports of raw materials for the manufacture of glue and finished products based on the trend of exports of domestic enterprises, which will help solve problems of adapting statistical analysis methods to real economic activities. Methodology. In the study of the state and trends of foreign trade of Ukraine in raw materials for the manufacture of glue and finished products with all countries used tabular-graphical method and systematic analysis; when developing a medium-term forecast - the method of extrapolation. Results. The application of statistical methods allowed to identify patterns and trends in foreign economic activity (FEA), and to determine the optimal directions for entry into the foreign market Bristol Eco Group Ltd. technological renewal of production, expanding relationships with customers and suppliers, finding new customers, increasing traditional products , and active renewal of their range, expansion of markets through penetration into the markets of the Republic of Moldova, Belarus, Uzbekistan and Azerbaijan. The following directions of development of Bristol Eco Group LLC were identified: according to the optimistic scenario: formation of the strategy of market expansion - penetration into the markets of the Republic of Moldova and Belarus; optimization of the product "portfolio" of the enterprise; development of an effective competitive strategy (diversification); sales promotion (promotion of goods based on the ratio of "price / quality"); according to the pessimistic scenario: either complete reorganization and reorganization of the enterprise, or its sale to the main competitor. Prospects for further research. It is determined that for the effective functioning of the company LLC "Bristol Eco Group", it is advisable to create a department of foreign economic activity, which will contribute to the deepening of trade relations with foreign partners and will provide an opportunity to improve its export potential.

The questions of spatial development as a modernization driver (the Kazakhstan case) are considered in this article. The analysis of the regional economic differences makes possible to work out the development guidelines, based on the advantages combination of the basic goods specialization and the policy of transferring growth impulses from the raw materials sector to the industry and service ones. Current challenges and opportunities, which face the Kazakhstan economy, the questions of economic diversification drive up the importance of the connection between spatial development and the cluster priorities. The analytical scheme of macro-regions and diversification through the dynamic focal networks can settle up these challenges.
