Jakarta's air quality on Tuesday, October 31, 2023, at 9:00 AM WIB was monitored as unhealthy, with PM2.5 concentrations three times the WHO's safe standard. This concentration is unhealthy for sensitive groups.
According to the Air Pollutant Standard Index (ISPU) page of the Ministry of Environment and Forestry (KLHK), Jakarta's average air quality index was 86, with an average PM2.5 concentration of 44.6 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 generally unhealthy for sensitive groups from 1:00 AM to 9:00 AM WIB.
The lowest PM2.5 concentration in Jakarta's air was 29.1 µg/m³ at 1:00 AM WIB, while the highest PM2.5 concentration was 44.6 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
