QUANTITATIVE AND QUALITATIVE CHEMICALANALYSIS OF SMOKELESS TOBACCO NASVAY

Abstract

Introduction. Nasvay is one of the smokeless tobacco, which is very popular in Central Asia.
Sublingual use of which reinforces the effect of the toxic ingredients, primarily on the heart, blood
vessels, the nervous system, and then accelerates addictive.
The purpose of the study. To conduct a quantitative and qualitative chemical compositional
analysis of a smoke-free tobacco nasvay, one kind of a smokeless tobacco and to compare it with
GOTHIATEK standard.
Materials and methods. The study of the chemical composition nasvay one of the types of
smokeless tobacco was held at the Laboratory Research & Development, Chemical Analysis,
Swedish Match Scandinavia Division SE-118 85 Stockholm Sweden. Nasvay had been bought on the
market of Karaganda. Multiple and batch method of analysis of pesticides in tobacco and tobacco
products has been conducted. Theoretical probability of the occurrence of substances concentration
in the compared specimen with GOTHIATEK standard has been researched through z-test. Critical
level of distinction has been revealed on the level no less than (<) 0,05. The calculation has been
conducted in SAS software.
Results. In the study we found no pesticide residues. Bacterial inoculation showed us the high
dissemination of bacteria in two batches of nasvay that indicates a lack of sterile (clean) conditions
during manufacture, transport and storage nasvay. In tobacco nasvay we found a large number of
nitrite ions in comparison with indicators of the standard GOTHIATEK. Level of Tobacco-specific Nnitrosamines (TSNA) was either just above or consistent with GOTHIATEK, like Swedish snus, which
indicators are within the normal standard GOTHIATEK. In the study of different samples of impurities
nasvai, we found the same elements, such as benzo (a) pyrene, chromium, nickel, cadmium, lead
and arsenic. This suggests that they were made in one way. But due to the fact that the amount of
these elements between samples differs dramatically from one another, this means that the
production of nasvai occurred with handicraft methods and ingredients for its production were added
without accurate accounting. The number of chromium, nickel, cadmium, lead and arsenic are
overstated of standard GOTHIATEK.
Conclusions. Nasvay is dangerous to human; according to literature data the revealed by us
components have toxic or carcinogenic activity.
