Jakarta Air Quality Unhealthy for Sensitive Groups at Night: KLHK's Latest 8-Hour Data (Thursday, November 2, 2023)

Jakarta's air quality on Thursday, November 2nd, 2023, at 7:00 PM WIB was recorded as unhealthy, with PM2.5 concentration 2.9 times the WHO's safe standard limit. 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 85, with an average PM2.5 concentration of 43.6 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.

Meanwhile, the development of Jakarta's air quality over the past 8 hours shows that the air was generally unhealthy for sensitive groups from 11:00 AM to 7:00 PM WIB.

The lowest PM2.5 concentration in Jakarta's air was 26.7 µg/m³ at 12:00 PM WIB, while the highest PM2.5 concentration was 45.3 µg/m³ at 3:00 PM 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 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
