Annual mean benzene concentrations

The map shows the annual mean benzene concentrations in 2011, based on annual averages with percentage of valid measurements >= 50% in μg/m3

Units

μg/m3

Additional information

Dark green dots correspond to concentrations under the WHO reference level (1.7 μg/m3).
Pale green dots correspond to concentrations under the lower assessment threshold (2 μg/m3).
Orange dots correspond to concentrations between the lower and the upper assessment threshold (3.5 μg/m3).
Red dots correspond to concentrations under the limit value of 5 μg/m3 but higher than the upper assessment threshold.
Dark red dots correspond to concentrations exceeding the limit value of 5 μg/m3.
The data coverage criterion has been set to 50 % by an European Commission working group on benzene (Mol et al., 2011).
