What is Particulate Matter (PM)?

[ Exposure to Particulate Matter(PM)  Ranks 6th as the Leading Cause of Premature Deaths Globally. ]

  • Also know atmospheric particulate matter, can be either solid or liquid matter suspended in the Earth's atmosphere. 

  • Size of PM vary dramatically and correlates directly how it impacts human health from Ultrafine <0.1um, Fine Particles <2.5um to Coarse Particles 2.5-10um.

  • In addition to the particle aerodynamic diameter in micron measurement (um) PM is also classified as either primary or secondary, secondary created by precursor gases such as sulfur dioxide and nitrogen dioxide.

  • Most US government organizations monitor PM2.5 continuously also known as PARTICLE POLLUTION.

  • Particulate Matter can be either natural or anthropogenic. Natural sources come from sea spray, volcanic ash and forest fires.

  • Elevated PM2.5/10 cause significant health affects ranging from decreased lung function, triggering asthma, bronchitis, lung infection, lung cancer to heart disease.

  • Cooking without using a venting fan increases your indoor PM levels 10-20x above normal limits.

  • Using wood stoves, heat stoves, fireplaces, and other combustiblle appliances can increase your indoor PM2.5/10 levels.

  • People sensitive to PM2.5/10 are individuals with respiratory diseases, the elderly, pregnant women and children.
