What is Particulate Pollution?
There are a number of significant sources of particulate matter which occur during the winter, such as industry, vehicles and wood burning smoke. State and local permitting requirements control the amount of particles emitted from industry, vehicles, and forest and agricultural practices, while local residential home heating programs control particulate emissions from wood stoves and fireplaces. All smoke contains particles that range in size from coarse and very fine. Health studies have determined that very fine particles are more detrimental to health than larger particles. For this reason, the federal government has established 2 particulate standards PM10 and PM2.5. The PM10 standard measures respirable particles less than 10 microns in size, while the PM2.5 standard measures respirable particles less than 2.5 microns in size. LRAPA uses the PM2.5 standard with it's advisory program to better protect the community from the negative impacts of smoke.
