CCARPH-MO Scientists Release Latest Findings on Impact of Taal Volcano Eruption on Air Quality: Air Quality Measurements and Current Plume Conditions (Part 2)

Buod Pangkaraniwan (as of 17 January 2020)

Pagkatapos ng pagputok ng Bulkang Taal noong ika-12 ng Enero, naitala sa Kalakhang Maynila ang bahagyang pag-akyat ng lebel ng mga partikulong mapanganib sa kalusugan dahil kaya nilang manatili sa baga. Mas malaki ang karamihan ng abo na umabot sa lupa (ngunit maaari pa ring magdulot ng iritasyon). Mula noong umaga ng ika-13 ng Enero, balik-normal na ang kalidad ng hangin sa Kalakhang Maynila. 

Kung sakaling pumutok muli ang Bulkang Taal, minumungkahi ang maayos na pagsuot ng surgical masks,lalo na sa mga bata, matatanda, at mga may hika. Dapat rin mag-ingat sa paglilinis ng natitirang aboupang hindi ito malanghap.

Non-Technical Summary (as of 17 January 2020)

In Metro Manila after the 12 January Taal eruption, we measured only moderately elevated levels of dangerous particles small enough to remain in the lungs. Most volcanic particles that reached the ground were larger (though can still cause irritation). Since the morning of 13 January, air quality has been back to normal in Metro Manila.

In case of future eruptions, use of properly fitting surgical masks is recommended as a precautionary measure, especially for sensitive groups (children, the elderly, and people with respiratory problems). It is also recommended to carefully clean up any remaining ash to minimize future exposure.

Summary (as of 17 January 2020)

  1. Current conditions at the Manila Observatory, Quezon City are back to normal. Previous 24-hour PM2.5 concentration range at the Manila Observatory (5-27 μg/m3) is within “good” levels based on the United States Environmental Protection Agency (US EPA) hourly PM2.5 standard.
  2. Pollution levels measured from the Manila Observatory and Barangay Fortune (Marikina City) towards the end of the ashfall event on 12 January 2020 were elevated, reaching “moderate” (US EPA hourly PM2.5 standard) but still significantly lower than pollution levels associated with the 2020 New Year’s Day celebrations.
  3. Ash particles from the 12 January eruption in Quezon City were too large to get into the lungs, but caution is still advised as physical processes (grinding) may break larger particles into smaller, respirable particles. It is recommended to clean up any remaining ash to minimize future exposure.
