Volcanic smog, or vog, continues to affect the Philippines today, with the Philippine Institute of Volcanology and Seismology (Phivolcs) reporting that sulfur dioxide (SO2) emissions from Taal Volcano remain elevated.

Vog is the result of volcanoes emitting a blend of gases and particles, which then interact with atmospheric moisture, oxygen, dust, and sunlight, ultimately leading to the creation of a hazy condition. 

Cities located in the vicinity of Taal Volcano are on alert, and vog has spread over Metro Manila as well, causing the suspension of classes in some cities on Friday, Sept. 22. 

According to Phivolcs, the components found in volcanic smog have the potential to induce irritation in the eyes, throat, and respiratory passages, with the degree of discomfort varying based on the concentration of these gases and the duration of exposure.

Individuals who have asthma, lung ailments, or other respiratory disorders face a heightened susceptibility to experiencing severe health complications as a result of their exposure to volcanic smog.

Volcanic smog can also travel long distances, so it is possible that other cities in the Philippines may also be affected, depending on the wind conditions.

Manila Bulletin asks Vichka Sison M.D., DSBPP, and third step psychiatrist of Mindcare Club, a telemental health company, for advice, "It would be best to stay indoors and wear a mask, if it is a necessity to go outside. If the individual has a pre-existing respiratory disease, it could be exacerbated such as asthma or COPD (chronic obstructive pulmonary disease)."

Dr. Vichka also advised people to limit their exposure to vog by avoiding outdoor activities. Those who must go outdoors are advised to wear an N95 facemask to protect themselves from the harmful gases.

"If your coughing worsens and you feel like something is obstructed while you're breathing, please have a check-up," she continued. "It is also possible that the vog cause eye irritation. If the itchiness of your throat or eyes persist, then it is best seek medical attention immediately."
