Assessment of population exposure to air pollution by benzene.

Biomonitoring is one of the methods that allow to identify population groups that have significantly higher exposures to a particular chemical than the general population. However, use of biomonitoring is particularly useful when applied in combination with other methods of pollution exposure assessment. The current study is focused on the developing of the modelling approach to estimate population exposure to benzene through inhalation. The model is based on a microenvironment approach and is adapted to be applied in urban areas where the pattern of exposure is complex. The results provided by the model may be used in combination with human biomonitoring in order to select who and where should monitoring be done, as well as for interpretation and extrapolation of biomonitoring results.
