PM2.5 refers to particles that have diameter less than 2.5 micrometres (more than 100 times thinner than a human hair) and remain suspended for longer. These particles are formed as a result of burning fuel and chemical reactions that take place in the atmosphere. Natural processes such as forest fires also contribute to PM2.5 in the air.

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.

Specific health problems due to PM2.5 include coughing, wheezing, shortness of breath, and aggravated asthma. PM2.5 is predominantly generated by traffic and domestic fuel combustion and has significant negative health impacts. The ever-growing urban population spends most of their time in indoor environments where it is exposed to PM2.5 that is brought in from the outdoor environment by ventilation airflow.
