MANILA, Philippines — The haze seen over Metro Manila is from pollution caused by human activities and not because of emissions from Taal Volcano, the Philippine Institute of Volcanology and Seismology said Tuesday in response to public concerns about volcanic smog, or 'vog'. Phivolcs on Monday warned people living near Taal Volcano to take precautions against volcanic smog formed because of atmospheric conditions and sulfur dioxide emissions from the volcano, where Alert Level 2 remains raised. IQAir recommends wearing a mask outdoors, closing windows to keep dirty outdoor air out and running an air purifier. It said people at risk of exposure to sulfur dioxide should wear N95 face masks or gas masks and drink plenty of water to help alleviate irritation and difficulty in breathing. They should also stay away from the source of volcanic gas and stay indoors with the windows closed to minimize exposure.
