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.
f) - Total suspended particulates, lead, and sulfate were determined
from samples collected every 6 days by the high volume sampler method, on
glass fiber filter media. Federal TSP standard superseded by PM10 standard, July 1, 1987.
