In October 2005, Task Force on Air Pollution criticised the Government for deluding itself with a pollution index that is a "meaningless" indicator of health risks. [4] Professor Wong Tze-wai, at the Chinese University of Hong Kong commented that the current air pollution index "gives a false sense of security". [4]
Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike. Air pollution is a particularly big problem in emerging and developing countries, where global environmental standards often cannot be met. The data in this list refers only to outdoor air quality and not indoor air quality, which ...
Clean Air Network (CAN, traditional Chinese: 健康空氣行動; simplified Chinese: 健康空气行动) is an independent non-governmental organisation exclusively focused on the issue of air pollution in Hong Kong. CAN aims to educate the public about the health impacts of air pollution and to mobilise public support for cleaner air in Hong Kong.
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 ...
For instance, some places like Africa and South America lack air pollution reporting tools, so their pollution levels are probably not reflected in this list. Moreover, many cities from a certain country are featured in the list may only mean that they have large and wide air pollution monitoring networks, which may or may not be an indicator ...
In the 2024 “State of the Air” report by the American Lung Association, despite decades of progress cleaning up air pollution, 39% of people living in America (131.2 million people) still live ...
On 8 March 2012, the department started reporting data on fine suspended particulates in the air on an hourly basis, that are a leading component of smog. It began regular monitoring of PM2.5 levels, which measure 2.5 micrometres in diameter or less, at three stations since 2005, but the data were never publicised.
The Southeast Asian haze is a fire-related recurrent transboundary air pollution issue. Haze events, where air quality reaches hazardous levels due to high concentrations of airborne particulate matter from burning biomass, [1] have caused adverse health, environmental and economic impacts in several countries in Southeast Asia.
