Jakarta’s air quality has deteriorated for the past two weeks, achieving “unhealthy” and “very unhealthy” statuses, which experts say is the result of trans-boundary pollution from neighboring cities and as such is an issue beyond the capital’s borders. (Jakarta post)
BMKG’s Acting Deputy for Climatology, Urip Haryoko explained here on Tuesday that the concentration of PM2.5 rocketed to the level of 148 μg/m3 on June 15, 2022, which showed the air quality was unhealthy.
He noted that the guideline value (NAB) of PM2.5 concentration is 65 μg/m3. He explained that between 15-65 μg/m3, air pollution was at a moderate level, and at 0-15 μg/m3, the air quality falls into the good category. When the value is at a concentration of 66-150 μg/m3, it is unhealthy; 151-250 μg/m3 is very unhealthy; and when it is more than 250 μg/m3, it falls in the hazardous category.
He explained that the decline in air quality in the Jakarta area and its surroundings had been caused by a combination of emission sources from air pollution contributors and meteorological factors that were conducive to accumulating the PM2.5 concentrations.
Haryoko noted that the increase in PM2.5 concentration can negatively impact individuals, with a history of respiratory and cardiovascular illness, and can cause infections in the lungs if inhaled long-term.
Hence, he urged people to reduce outdoor activities and use personal protection equipment, such as proper masks, to lower their level of exposure to air pollutants.
