The air quality in Malaysia is reported as the Air Pollution Index (API). Four of the index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) are reported in ppmv but PM 10 particulate matter is reported in μg/m 3. This scale below shows the health classifications used by the Malaysian government. 0-50 Good
An air quality index (AQI) is an indicator developed by government agencies [1] to communicate to the public how polluted the air currently is or how polluted it is forecast to become. [2][3] As air pollution levels rise, so does the AQI, along with the associated public health risk. Children, the elderly and individuals with respiratory or ...
The air quality in Malaysia is reported as the API (Air Pollutant Index) or in Malay as IPU (Indeks Pencemaran Udara). Four of the index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) are reported in ppmv but PM 2.5 particulate matter is reported in μg/m 3.
Air pollution is among the biggest health problems of modern industrial society and is responsible for more than 10 percent of all deaths worldwide (nearly 4.5 million premature deaths in 2019), according to The Lancet. Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike.
The Air Pollution Index (API) is used by the government to describe the air quality in Malaysia. The API value is calculated based on average concentrations of air pollutants, namely sulphur dioxide, nitrogen dioxide, carbon monoxide, ozone and fine dust (PM 10). The air pollutant with the highest concentration is the pollutant that will ...
Deforestation in Malaysia is a major environmental issue in the country. British colonial deforestation efforts began in 1880 and were rapidly driven by commercial rubber and palm oil cultivation. Between 1990 and 2010, Malaysia lost an estimated 8.6% of its forest cover, or around 1,920,000 hectares (4,700,000 acres). [ 4 ]
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 ...
A trans-national air pollution crisis affected several countries in Southeast Asia from February to September 2019, including Brunei, Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam. Thailand began to experience a haze in February that lasted until May, peaking in March and April. Indonesia began to experience haze ...
