Jakarta Air Quality Unhealthy for Sensitive Groups at Night: Last 8 Hours (Friday, November 3, 2023)

Jakarta's air quality on Friday, November 3, 2023, at 7:00 PM WIB was recorded as unhealthy, with PM2.5 concentrations 3.2 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 91, with an average PM2.5 concentration of 48.4 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 34.6 µg/m³ at 2:00 PM WIB, while the highest PM2.5 concentration was at 4:00 PM WIB with a value of 49.2 µg/m³.

Quoting the Meteorology, Climatology, and Geophysics Agency (BMKG) website, PM2.5 are small 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
