The results showed that although vapour recovery technologies are installed in the refuelling systems and benzene
emissions are significantly reduced compared to the past, filling station employees are still highly exposed to benzene
(52–15mgm
3
). Benzene exposure is strongly correlated to car refuelling (exposure levels up to 85mgm
3
), while activities
like car washing or working in cash machine inside an office contribute to lower exposure levels (up to 44 and 24 mgm
3
respectively)
