Areas 9, 10, 23, 30 and 34 have two monitoring stations each. Values shown are the highest recorded at either station.

µg/m3 - Micrograms per cubic meter of air.
AAM - Annual Arithmetic Mean.
AGM - Annual Geometric Mean.
-- - Pollutant not monitored.
* - Less than 12 full months of data. May not be representative.
e) - PM10 samples were collected every 6 days using the size-selective inlet high volume sampler with quartz filter media. (PM10 refers to the finer suspended particles, consisting of particles with diameter less than approximately 10 micrometers.)
g) - Federal PM10 standard is AAM > 50 µg/m ; state standard is AGM > 30 µg/m .
