Particulate matter (PM) is a common air pollutant harmful to human health that is recognized for monitoring and mitigating by the <\/span><\/i>World Health Organization<\/span><\/i><\/a> and <\/span><\/i>Breeze Technologies<\/span><\/i><\/a>. Read on to find out more.<\/span><\/i><\/p>\n

What is particulate matter?<\/span><\/h2>\n

Particulate matter<\/span><\/a> consists of solid and liquid airborne particles and is<\/span> classified by the size of its particles<\/span><\/a>. <\/span>PM<\/span>10<\/span><\/sub> are coarse particles that have diameters that are less than or equal to 10 micrometres, while PM<\/span>2.5<\/span><\/sub> are fine particles with diameters less than or equal to 2.5<\/sub> micrometres. For scale, the human hair has a diameter of roughly 70 micrometres. There are also newer classifications such as <\/span>PM<\/span>0.1<\/span><\/sub>, PM<\/span>0.3<\/span><\/sub>, PM<\/span>0.5<\/span><\/sub>, PM<\/span>4<\/span><\/sub>, and PM<\/span>5<\/span><\/sub><\/a>, <\/span>but the aforementioned PM<\/span>2.5<\/span><\/sub> and PM<\/span>10<\/span><\/sub> are the main ones, as they are regulated.<\/span><\/p>\n

What are sources of particulate matter?<\/span><\/h2>\n

Primary particulate matter<\/span><\/a> is emitted from a direct source, such as power plants, factories, <\/span>diesel and petrol engines, vehicle braking, tire-wear<\/span><\/a>, construction sites, <\/span>forest fires<\/span><\/a>, volcanos, <\/span>dust storms<\/span><\/a>, stoves, heaters.<\/span><\/p>\n
