The general population is exposed to the genotoxic carcinogen glycidol via food containing refined edible oils where glycidol is present in the form of fatty acid esters. In this study, internal (in vivo) doses of glycidol were determined in a cohort of 50 children and in a reference group of 12 adults (non-smokers and smokers). The lifetime in vivo doses and intakes of glycidol were calculated from the levels of the hemoglobin (Hb) adduct N-(2,3-dihydroxypropyl)valine in blood samples from the subjects, demonstrating a fivefold variation between the children. The estimated mean intake (1.4 μg/kg/day) was about two times higher, compared to the estimated intake for children by the European Food Safety Authority. The data from adults indicate that the non-smoking and smoking subjects are exposed to about the same or higher levels compared to the children, respectively. The estimated lifetime cancer risk (200/105) was calculated by a multiplicative risk model from the lifetime in vivo doses of glycidol in the children, and exceeds what is considered to be an acceptable cancer risk. The results emphasize the importance to further clarify exposure to glycidol and other possible precursors that could give a contribution to the observed adduct levels.

This paper deals with the analysis of risks which threaten the future sustainability and operations of agricultural museums in the Czech Republic. In the section on methodology, an applicable risk model has been proposed regarding the condition of museums in the Czech Republic. Using this model, the directors of agricultural museums can assess the most significant risks which may jeopardize the sustainability of museum operations over a three-year period. The greatest risks, according to museum directors, are a lack money for investment, the inability to retain high-quality staff, and issues with technical support for exhibitions. Assessing the importance of risk is positively associated with previous experiences of a particular type of risk, whereas the association of the importance of risk with previous managerial practice is rather inconclusive.
