Comparative Health Risk Assessment of Heated Tobacco Products versus Conventional Cigarettes.

BACKGROUND: Smoking is the largest preventable cause of death in the world with around eight million estimated premature deaths per year. In response to the harmful effects of conventional tobacco products the tobacco industry has launched a new type of products called Heated tobacco products (HTP) and e-cigarettes, which are considered safer for human health than conventional cigarettes. MATERIALS AND METHODS: The research was conducted by searching the scientific literature using platforms "Google scholar," "PubMed" and "Science Direct." To compare the non-carcinogenic and carcinogenic risk of HTP products and conventional cigarettes, margin of exposure and lifetime excess cancer risk were calculated using data obtained from a scientific literature search.HTP products have shown a reduced risk to human health compared to the conventional cigarettes, although they still contain compounds that can be dangerous to human health. There is not enough data obtained from independent studies that could safely indicate that these reduced amounts of toxic chemical entities in the composition of HTP do not induce any harmful effect. CONCLUSION: Further research is needed to determine the harmful effects of HTP aerosol, as well as to tighten the legislation that would limit the production, import and distribution of these products worldwide until their safety for human health is confirmed with a sufficient number of transparent and representative results obtained in independent scientific studies.

Health risk assessment of ethyl carbamate in fruit spirits.

Alcoholic beverages are multicomponent mixtures containing several carcinogenic compounds, including ethyl carbamate, which was evaluated in fruit spirits against the limit proposed by the International Alliance for Responsible Drinking (IARD) and then in terms of associated health. It was above the limit in 40% of the samples and statistically higher in stone fruit spirits. The MOE values below the limit were obtained for 49% and 98% of the samples at average and chronic heavy consumption by men, while for women the limit was reached by 19% and 96% of the samples, respectively. The lifetime cancer risk (LCR) approach based on the oral slope factor indicated risk concern for 96% of the samples at average consumption, regardless of gender, while LCR based on virtually safe dose indicated 25% and 69% of the samples posing a risk to women's and men's health, respectively. Preventive measures during spirit production and legal regulation of ethyl carbamate should be considered.
