Air pollution levels in Manila's Freedom Park drop by 42% after ECQ

The air pollution level at Freedom Park, Manila City Hall has dropped by more than 40 percent in comparison to levels before the implementation of the enhanced community quarantine (ECQ).

According to the Manila PIO, based on the air quality monitoring performed under the Asia Blue Skies Program, officials found that PM2.5 (atmospheric particulate matter) levels dropped by 42 percent.

This week's data, however, is reportedly 12 percent higher compared to last week's data.

PM2.5 is a particulate matter, with an average size of 2.5 micrometers, which is bad for the environment and health.

"The air quality monitoring data that is being collected, along with the emissions inventory and health mapping results, will be used to better understand the state of air quality in the city," the Manila PIO said.

"All of these will be used as the basis for the development of Manila City's Clean Air Action Plan which will be completed by end of 2020," it added. —Joahna Lei Casilao/LDF, GMA News
