In view of this, filter samples of airborne particulate matter (particle diameter ?2.5 ?m, PM2.5) were collected between May 2008 and April 2010 at two sites
Particulate matter, one of six U.S. EPA criteria air pollutants, is a mixture that can include organic chemicals, dust, soot and metals. These particles can come from cars and trucks Indoor PM 2.5 is composed of indoor-generated PM 2.5 from sources such as smoking, cooking, and cleaning, and PM 2.5 that has infiltrated from the outside. In studies conducted by Health Canada in different Canadian cities, average indoor PM 2.5 concentrations were less than 15 µg/m 3 in homes without smokers, and less than 35 µg/m 3 in homes with smokers (Health Canada 2010). pm2.5予測情報の提供を維持するために寄附を募集しています → ご案内 sprintarsの解説も書かれている一般向け書籍「異常気象と気候変動についてわかっていることいないこと」発売中 PM2.5 exposure causes respiratory and cardiovascular disease and, ultimately, death. • The main sources of urban environment PM2.5 are traffic and domestic combustion. • Cooking, heating and particle re-suspension are the main indoor sources of PM2.5.
1 Due to its small size, PM2.5 can remain suspended in the air for long periods of time and can be absorbed deep into the bloodstream upon inhalation. What are the sources of PM2.5 pollution? PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometers, which is about 3% the diameter of a human hair. Commonly written as PM 2.5, particles in this category are so small that they can only be seen with a microscope.

If the PM 2.5 levels in your area are elevated, it's important to safeguard your system from excessive exposure by staying indoors, or wear a mask that can filter pm2.5 on high-pollution days.

Koncentrationen av PM2,5 har minskat sedan år 2000 och endast i södra Sverige överskrids miljömålets årsmedelvärde, 10 µg/m3.
I Sverige finns sedan 2014 ett miljömål på att PM2.5 ska vara under 10 μg/m3. Ett filter som klassas med PM2.5, 60 %, innebär att filtret tar bort 60 % av Luftkvalitetsindex (AQI) beräkning.
