Air Pollutant Index is calculated based on the 1-hour average of the concentration levels of PM 25 PM 10 sulphur dioxide SO 2 nitrogen dioxide NO 2 ozone O 3 and carbon monoxide CO. The Air Pollution Index API serves as a way to identify days when air quality is good or poor and it is primarily associated with human health.

Air Pollutant Index API or Indeks Pencemaran Udara IPU is the indicator of air quality status in Malaysia.
. Or let us find your nearest air quality monitoring station Air Quality Index AQI Values. Malaysia has worked with the Indonesian authorities to help curb peat fires. What is API Air Pollutant Index.
Air Pollutant Index of Malaysia APIMS Also known as the Index Pencemaran Udara IPU in Malay. The API value is calculated based on average concentration of air pollutants namely SO 2 NO 2 CO O 3 PM 25 and PM 10. Air Pollutant Index of Malaysia APIMS is the official application and website of the Department of Environment Malaysia DOE for reporting the air quality and level of.
Check out the real-time air pollution map for more than 100 countries. Air Pollutant Index API is an indicator for the air quality status at any particular area. The index values range from 0 to 500 with lower values associated with better air quality and lower health risks.
The air quality in Malaysia is reported as the Air Pollution Index API. APIMS is a website that provide information of the latest API readings at Continuous Air Quality Monitoring CAQM stations in Malaysia based on standard health classification. The readings of fine particulate matter or PM25 in the air that gave it this ranking came in at 215µgm³ putting it into the moderate rating bracket which requires a PM25 rating of between 121 to 354 µgm³ to be classed as moderate.
The air pollutant with the highest concentration dominant pollutant which is usually PM 25 will determine the API value. Malaysia - States Air Pollution Level Malaysia - Metro Cities AQI New York 97 AQI US 22C 59 Melbourn 16 AQI US 13C 72 New Delhi 56 AQI US 31C 63. Malaysia and Indonesia together with other members of the ASEAN community signed the ASEAN Agreement on Transboundary Haze Pollution in 2002 as a result of a.
A state of emergency was announced in 2005 at Port Klang as the Air Pollution Index API went above 500. Air Pollution Index Flowchart The ambient air quality measurement in Malaysia is described in terms of Air Pollutant Index API. A specific colour shape is assigned to each Air Pollutant Index API category to make it easier for the people with colour vision deficiency to understand the status of air quality.
The Air Pollution Index API is a simple and generalized way to describe the air quality which is used in MalaysiaIt is calculated from several sets of air pollution data and was formerly used in mainland China and Hong KongIn mainland China the API was replaced by an updated air quality index in early 2012 and on 30 December 2013 Hong Kong moved to a health based index. Good 0 - 50 Moderate 51 - 100 Unhealthy 101 - 200 Very Unhealthy 201 - 300 Hazardous Above 300 API Table Hourly. In August 2018 Malaysia added PM25 to the calculation of its Air Pollution Index which means it now bases its Air Pollution Index on the average concentrations of six air pollutants.
The air pollutants included in Malaysias API are ozone 03 carbon monoxide CO nitrogen dioxide N02 sulphur dioxide S02 and suspended. This scale below shows the health classifications used by the Malaysian government. Four of the indexs pollutant components ie carbon monoxide ozone nitrogen dioxide and sulfur dioxide are reported in ppmv but PM 10 particulate matter is reported in μgm 3.
The shapes are shown as below. Malaysia Major Air Pollutants in Malaysia PM25 The current PM25 concentration in Malaysia is below the recommended limit given by the WHO 24hrs air quality guidelines value. PM25 PM10 PM25 sulphur dioxide nitrogen dioxide carbon monoxide and ozone.
The air pollutant with the highest concentration dominant pollutant will determine the API value. Within this range there are 5 API categories which are defined based on a given. The API is developed in easily understood ranges of values as a means of reporting the quality of air instead of using the actual concentration of air pollutants.
