Jakarta's air quality on Thursday, December 14, 2023, at 9:00 AM WIB was recorded as unhealthy, with PM2.5 concentrations 2.9 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 84, with an average PM2.5 concentration of 43.1 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.
Meanwhile, the development of Jakarta's air quality over the past 8 hours shows that the air was unhealthy for sensitive groups from 1:00 AM to 9:00 AM WIB.
The lowest PM2.5 concentration in Jakarta's air was 37.8 µg/m³ at 1:00 AM WIB, while the highest PM2.5 concentration was 43.1 µg/m³ at 9:00 AM WIB.
Quoting the Meteorology, Climatology, and Geophysics Agency (BMKG) website, PM2.5 are small airborne particles measuring 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 divides PM2.5 air pollution levels into several categories:
* 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
