Jakarta's air quality tonight is unhealthy for sensitive groups, with pollutant levels exceeding the WHO safe limit by 2.7 times.

Jakarta's air quality on Thursday, December 14, 2023, at 7:00 PM WIB was recorded as unhealthy, with PM2.5 concentration 2.7 times the WHO's safe standard. This concentration is unhealthy for sensitive groups.

According to the Ministry of Environment and Forestry's Air Pollutant Standard Index (ISPU) page, Jakarta's average air quality index was 81, with an average PM2.5 concentration of 40.8 µg/m³ (micrograms per cubic meter) at 7:00 PM WIB.

According to WHO standards, good air quality has an average 24-hour PM2.5 concentration range of 0 to 15 µg/m³.

Over the past 7 hours, Jakarta's air quality has been consistently unhealthy for sensitive groups from 11:00 AM to 7:00 PM WIB.

The lowest PM2.5 concentration in Jakarta's air was 33.1 µg/m³ at 3:00 PM WIB, while the highest was 43.5 µg/m³ at 12:00 PM WIB.

Quoting the Meteorology, Climatology, and Geophysics Agency (BMKG), PM2.5 are tiny 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 exposure to PM2.5 can lead to premature death, chronic heart and lung diseases, 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
