phthalates contamination, phthalates migration, sorption of phthalates, wine industry products, analytical procedure


Dissertation contents: introduction, 5 chapters, general conclusions and recommendations, bibliography - 176 references, 9 annexes, 118 pages of the main part, 57 pictures and 30 tables.

Number of publications: results are published in 13 scientific papers. Field of research:166.02. Environmental protection and rational use of natural resources.

The aim of the work: The purpose of research was to develop an efficient, reliable, available, economically viable procedure of analysis of the both wine industry final product, and any raw materials used in the production process; identifying the sources of contamination of wine products with phthalates; in addition, the study of the migration of phthalates in an aqueous- alcoholic solutions and determining the factors affecting on speed of this process; study of the phthalates content changes in alcohol-matrix under the influence of physical, physic-chemical and biological factors .

Scientific novelty and originality of the research is to determine the factors influencing the process of migration of phthalates from polymeric materials to water-alcohol solutions, such as temperature, time, mechanical impact, the components ratio in the binary system water-alcohol, and quantification of their impact;
The dynamics of phthalates content changes in processes of biological and abiotic sorption in alcohol-matrix was fixed;

The models of analytical approaches to the estimation of phthalates content in wine industry products were proposed.

In 2010 year the analysis procedure for the determination of phthalates’ content was the first document, formalized and approved at the national level document. The presented procedure is different from other theoretical approaches by its technical and economic availability.

Solved scientific problem: According to the study of natural sources of water, soil and plant materials, it was found that the objects of the environment are not sources of phthalate contamination of wine.

Theoretical and application value of the research: In this work there were studied aspects of evaluation of polymeric materials applicability in the wine industry;
Showing the factors contributing to the decline in natural phthalate contamination in the final products of the wine industry in the process of fermentation of the wort and physical-chemical treatment of raw wine.

The procedure, which was elaborated and approved in a national system National Accreditation Center of the Republic of Moldova (MOLDAC), is used by the National Center for Quality Testing of Alcoholic Beverages for the control of hygienic safety of the Moldovan wine industry products. protecţia mediului ambiant
