This index, reported by the Environmental Protection Department, is measured on a scale of 1 to 10+ and considers four air pollutants: ozone; nitrogen dioxide; sulphur dioxide and particulate matter (including PM10 and PM2.5).

The most harmful dose seems to be the first dose, up to about 25 or 50 micrograms. That should be motivation for even relatively clean cities like Hong Kong, Shenzhen, or even Chicago to keep working at reducing PM2.5. 2020-08-06 · Roadside PM10 pollution has reduced in the long-term and has been at a stable level since 2012 Average concentrations steadily declined to 17.2 µg/m 3 in 2015, a low since monitoring began in 1997. Technically, there isn’t a safe level of PM10, as any amount of particulate matter in your air isn’t a good thing. However, completely eliminating PM10 from your life isn’t a practical option. You will be exposed to coarse particles in some way during your day, but there are some guidelines you can follow to determine if the air is safe. The 1997 standards retained, but slightly revised, standards for PM 10, which limited PM 10 concentrations to 50 μg/m 3 based on an annual average, and 150 μg/m 3 based on a 24-hour average.

By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width. PM 10 and PM 2.5 are not used for any application. Currently, the WHO identifies safe levels of PM10 - particulate matter measuring under ten micrometres - as under 20 micrograms per cubic metre. This is much lower than the EU's safe particulate matter level, which stands at 40 micrograms per cubic metre.
