The January 2024 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 5,390 towns and cities in 63 countries. Air quality in the database is represented by the annual mean concentration of particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 micrometers, respectively). [1 ...
On December 30, 2013, Hong Kong replaced the Air Pollution Index with a new index called the Air Quality Health Index. [17] 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; sulfur dioxide and particulate matter (including PM10 and PM2.5).
The total land area of Hong Kong is 1,076 square kilometres, but about 75% of this land is open countryside, [1] which contains more than 2600 species of vascular plants, about 450 species of birds, about 200 species of butterflies, about 100 species of dragonflies, 40 species of mammals, 80 species of reptiles and more than 20 species of amphibians, including some that are endemic to the ...

Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike.
In Hong Kong, there were two types of API: General API and Roadside API. The EPD reported the latest APIs hourly. The index and the air quality objectives were set in 1987; and pollutant levels are measured over varying periods, in μg/m 3. There are hourly, 24-hour and annual targets for sulfur dioxide and nitrogen dioxide, and 24-hour and ...
