How does the DOH monitor air quality?
The DOH maintains stationary ambient air quality monitors that measure particulate levels in Hilo, Kona, Pahala and Mountain View stations on the Island of Hawai`i. Air quality monitors are also located on Maui and O`ahu. The DOH has monitoring stations for sulfur dioxide (SO2) on the island of O`ahu and Hawai`i where the majority of industrial and volcanic SO2 sources are.
