The red dots indicate stations reporting exceedances of the 2005 annual limit value (40 μg/m3), as set out in the Air Quality Directive. The orange dots indicate stations reporting exceedances of a statistically derived level (31 μg/m3) corresponding to the 24–hour limit value, as set out in the Air Quality Directive. The pale green dots indicate stations reporting exceedances of the WHO air quality guideline for PM10 of less than 20 μg/m3 but not in exceedance of limit values as set out in the Air Quality Directive. The dark green dots indicate stations reporting concentrations below the WHO air quality guideline for PM10 and implicitly below the limit values as set out in the Air Quality Directive.
