Epidemiological data has demonstrated that particulate matter (PM) with an aerodynamic diameter ≤ 2.5 µm (PM2.5) is associated with cancer incidence. However, the precise mechanisms underlying PM2.5‑mediated hepatocellular carcinoma cancer (HCC) migration and invasion remain unclear. The aim of the present study was to explore the response …

Other actions to reduce indoor PM 2.5 levels include ensuring there is adequate ventilation, especially when doing activities that may generate PM 2.5.The potential benefits of ventilation, however, may be reduced or eliminated, if outdoor PM 2.5 levels are high. There is also evidence that some in-duct air filters or portable air cleaners with filters may help …

Particulate Matter < 2.5 microns (PM2.5) - airborne particulate matter with a mass median diameter less than 2.5 µm. Numerous studies have linked PM to aggravated cardiac and respiratory diseases such as asthma, bronchitis and emphysema and to various forms of heart disease. PM can also have adverse effects on vegetation and structures, and ...
How to Read PM 2.5 Readings. Due to the many adverse effects fine particles can inflict on a large number of people, PM 2.5 is one of the major pollutants closely monitored by health authorities around the world. You will most likely come across a dedicated column for PM 2.5 alongside the Air Quality Index (AQI), Pollutants Standards Index (PSI) or the air …

Fine particulate matter (PM 2.5) is an air pollutant that causes serious health concern for people when levels in air are high. The particles are able to travel …
Ambient fine particulate matter (PM 2.5) is the world's leading environmental health risk factor. Reducing the PM 2.5 disease burden requires specific strategies that …
For particulate matter (PM), the NAAQS indicator evolved from total particle mass concentration, to PM 10 and PM 2.5 mass concentrations as defined by the PM …
The model was calibrated with daily PM 2·5 concentrations measured at 2156 monitors—data obtained from the US Environmental Protection Agency's Air Quality System database and IMPROVE monitoring network—and had excellent performance (10-fold cross-validated r 2 of 0·86 for PM 2·5 predictions across the USA, ranging from 0·77 in the ...
•Particulate matter (PM), also called particle pollution, is a general term for extremely small particles and liquid droplets in the atmosphere •PM 2.5 (fine particles): d ≤ 2.5 m •PM 10 (coarse particles): d ≤ 10 m •Primary sources: –Incomplete combustion –Automobile emissions –Dust –Cooking •Secondary sources:
미세먼지 (fine particles)는 부유분진 (Suspended particles), 입자상물질 (Particulate matter) 등으로도 불리며 명칭에 따라 약간씩 다른 의미를 가지고 있다. 입자상물질은 지름이 100μm에서 10나노미터 정도이며, 이보다 지름이 크면 …

PM 2.5 particles are small enough for you to breath them deeply into your lungs. Sometimes particles can enter your bloodstream. People who are sensitive to air pollution might experience symptoms when PM 2.5 levels are high. This includes people with heart or lung conditions. Symptoms can include: wheezing. coughing.
