AI Article Synopsis
- - The study analyzed the presence and movement of Polonium-210 (Po) in 16 brands of oral smokeless tobacco products purchased in Europe, using alpha spectrometry to measure its activity concentration.
- - Polonium-210 was found in all samples, with concentrations ranging from 3.46 to 14.8 Bq/kg, averaging 7.45 ± 3.82 Bq/kg, with the highest levels in chewing tobacco.
- - Despite low extraction rates (12.8 ± 8.96%) into artificial saliva during sucking or chewing, the findings indicate that Po is not entirely retained in the products, posing potential health risks for users.
Article Abstract
The occurrence and mobility of Po in oral smokeless tobacco products (STPs) were determined because its effects on human health must be taken into account. This research was subdivided into two parts: determination by alpha spectrometry of the Po activity concentration in 16 oral smokeless tobacco products of different brands purchased in local specialty stores in Europe and evaluation of its percent extraction into an artificial salivary gland during sucking or chewing operations. Polonium-210 was detected in all samples, and its concentrations ranged from 3.46 to 14.8 Bq kg (mean value of 7.45 ± 3.82 Bq kg). The highest concentration was found in chewing tobacco. The samples showed no significant difference in the content of Po level. The data obtained in this study show that the polonium, although poorly extracted (12.8 ± 8.96%) by artificial saliva, is not totally retained within the smokeless tobacco products, with a consequent potential health hazard associated with oral use of these products.
