☠️ Air pollution in Grogol keeps fluctuating

Check out the graph of air pollution levels in Grogol since June below!

From June to July, it seems that air pollution in Grogol often increases significantly and exceeds 100 µg/m3, causing the air in Grogol to be unhealthy. PM2.5 even reached 186.2 µg/m3 (Very Unhealthy) on June 18, 2023, or 37x above the WHO annual exposure limit! 😱

This is mainly caused by the presence of pollution sources (congenital and hyperlocal) in the neighborhood and the lower boundary layer at night which leads to the buildup of PM2.5 in the environment. This accumulation of PM2.5 concentration will be read as high pollution.

Let's sneak a peek at the air pollution data for last June and July! 👀

This is the air pollution data in Grogol for each hour from June to July 2023. According to the data, Grogol residents almost had no time with healthy air quality to breathe. In the last two months, Grogol residents breathed unhealthy air on average for the whole day 😷

The image above is hourly data showing the severity and horror of air pollution in Grogol Sutera in July. Almost every day, residents breathed in unhealthy air nonstop. Even beyond the red color, purple (the color that represents 'very unhealthy' air) is also visible at some times. Days with ‘Very Unhealthy’ air quality often occur in the early morning. Comparatively speaking, breathing the air in Grogol with such poor air quality is equivalent to smoking 455 cigarettes! 🚬

Furthermore, research jointly conducted by Nafas and a local telemedicine company in Jabodetabek from June to August 2022 stated that the number of consultations related to asthma attacks doubled in 10-17 hours when PM2.5 was in the Unhealthy category for Sensitive Groups 🚩

From the explanation of these data, it can finally be concluded that the level of air pollution in Grogol is worryingly high. The presence of pollution sources (hyperlocal and congenital) in the location can be one of the factors that affect the bad air in Grogol ☝🏻
