Greenpeace, netizens express concern over hazier than usual skies in Metro Manila

Greenpeace Philippines and several netizens have expressed concern over "hazier than usual" skies around Metro Manila on Monday.

In a Facebook post, the environmental organization shared some photos taken in Makati and Mandaluyong where skies are seen covering the cities with a grayish hue.

In one of the photos, air quality application IQAir stated that the air in Manila is "unhealthy."

Netizens have also come forward with their own observation of dark skies in their areas. Some of the locations mentioned include Pasig, Antipolo, Muntinlupa, and Pateros.

"No wonder our indoor air quality indicates alarming signals," one wrote.

"So that's why! Our purifier's air quality reading went up to 388 a couple of hours ago," another added.

Earlier Monday, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said volcanic smog or vog was seen over the Taal Volcano caldera.

PHIVOLCS added that should more vog be formed, the public should take the necessary precautions.

"It can cause irritation of the eyes, throat, and respiratory tract in severities depending on the gas concentrations and durations of exposure," it said.

People with asthma, lung disease and heart disease, as well as the elderly, pregnant women, and children, are among those sensitive to such ill effects of vog.

The public is encouraged to protect themselves by covering their noses, drinking plenty of water, and seeking medical attention if needed.
