Jakarta's air quality on Thursday, October 26, 2023, at 9:00 AM WIB was recorded as unhealthy, with PM2.5 concentration 3.6 times the WHO's safe standard. This concentration is unhealthy for sensitive groups.
According to the Ministry of Environment and Forestry's (KLHK) Air Pollutant Standard Index (ISPU) page, Jakarta's average air quality index was 97, with an average PM2.5 concentration of 54.3 µg/m³ (micrograms per cubic meter) at 9:00 AM WIB.
According to the WHO, good air quality has an average 24-hour PM2.5 concentration range of 0 to 15 µg/m³.
Jakarta's lowest PM2.5 concentration was 51.6 µg/m³ at 3:00 AM WIB, while the highest was 60.2 µg/m³ at 2:00 AM WIB.
Quoting the Meteorology, Climatology, and Geophysics Agency (BMKG) website, PM2.5 are tiny airborne particles measuring less than 2.5 microns, or about 3% of the diameter of a human hair.
Sources of PM2.5 include emissions from the combustion of gasoline, oil, wood, and other fuels. Long-term effects of PM2.5 exposure on the human body include premature death, chronic heart and lung disease, and reduced lung function in children.
For information, BMKG categorizes PM2.5 air pollution levels as follows:
* Good: 0 - 15.5 µg/m³
* Moderate: 15.6 - 55.4 µg/m³
* Unhealthy: 55.5 - 150.4 µg/m³
* Very Unhealthy: 150.5 - 250.4 µg/m³
* Hazardous: >250.5 µg/m³
