Air Pollutant Index (API) is an indicator for the air quality status at any particular area. The API value is calculated based on average concentration of air pollutants namely SO2, NO2, CO, O3, PM2.5 and PM10.
What is the API in Malaysia?
Air Pollution Index
The Air Pollution Index (API) is a simple and generalized way to describe the air quality, which is used in Malaysia. It is calculated from several sets of air pollution data and was formerly used in mainland China and Hong Kong.
What is the air quality in Malaysia?
In accordance with the World Health Organization’s guidelines, the air quality in Malaysia is considered moderately unsafe – the most recent data indicates the country’s annual mean concentration of PM2. 5 is 16 µg/m3, which exceeds the recommended maximum of 10 µg/m3.
Does Malaysia have haze?
Haze has been a major issue for the country, driven by slash and burn practices by farmers and peat fires blown by the wind from Indonesia. Malaysia has worked with the Indonesian authorities to help curb peat fires.
What is the difference between air pollution index and air quality index?
Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.
What is normal air pollution?
“Good” AQI is 0 – 50. Air quality is considered satisfactory, and air pollution poses little or no risk. “Moderate” AQI is 51 – 100. “Unhealthy” AQI is 151 – 200. Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.
How is API calculated?
#API score is calculated by dividing the actual score by 10 which is 1.5 API score.

Why is Kuala Lumpur so hazy?
Kuala Lumpur also has a long history of large fuel subsidies and large investment into road infrastructure, whilst leaving the public transport industry in the dust behind it. The fallout from this is a huge reliance and overuse of personal cars, contributing heavily to the smoke and haze in the city.
What AQI is unhealthy?
An AQI over 150 is considered unhealthy for the general population. AQI over 101 can be unhealthy for sensitive groups and some workers with asthma and other conditions may feel unhealthy when the AQI is below 150.
What are the 6 levels of air quality?
These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
