particulate matter (residue materials, <materials by origin>, ... Materials (hierarchy name)) |
|
Note: Extremely small particles and droplets suspended in air. They may include organic chemicals, acids, metals, and dust or soil particles. Also known as particle pollution, particulate matter is used as a measure of air pollution. The EPA groups inhalable pollutants which pass through the throat and nose and enter the lungs into two categories: “inhalable coarse particles” (between 2.5 micrometers and 10 micrometers in diameter); and “fine particles” (2.5 micrometers in diameter and smaller).

Additional Notes: |
|
| Dutch ..... Uiterst kleine deeltjes en druppeltjes in de lucht. Het kunnen organische chemicaliën, zuren, metalen of stof- of bodemdeeltjes zijn. De hoeveelheid fijnstof wordt gebruikt als maat voor luchtvervuiling. Het Amerikaanse Environmental Protection Agency groepeert inhaleerbare vervuiling die via keel of neus in de longen komt, in twee categorieën: 'inhaleerbare grove deeltjes' (PM10) met een diameter tussen 2,5 en 10 micrometer en 'fijne deeltjes' (PM2,5), van 2,5 micrometer en kleiner. |
