Opisyal na Sukatan ng AQI ng DOH at DENR
Mga pamantayan mula sa DENR at DOH para sa kalusugan ng mamamayan.
Air quality is satisfactory and poses little or no health risk. Ideal for all outdoor recreational and sporting activities.
Air quality is acceptable. Exceptionally sensitive people may experience minor respiratory symptoms.
Children, elderly, and people with heart or lung disease should limit prolonged outdoor heavy exertion.
Everyone may begin to experience health effects. Sensitive individuals should wear protective masks outdoors.
Health alert: Risk of health effects is substantially increased for everyone. Close windows and stay indoors.
Emergency health warning: Entire population is more likely to be affected. Avoid all outdoor physical activity.
Taal Volcano Vog & Philippine Air Quality FAQ
What is Taal Volcano volcanic smog (vog)?
Volcanic smog, or vog, is formed when sulfur dioxide (SO2) gas emitted during degassing at Taal Volcano interacts with atmospheric moisture, oxygen, and sunlight. This reaction creates a toxic acidic aerosol haze that irritates the eyes, throat, and respiratory tract.
What are the health risks of volcanic sulfur dioxide (SO2)?
Exposure to sulfur dioxide can cause severe throat irritation, coughing, breathing difficulties, and aggravated asthma or chronic obstructive pulmonary disease (COPD). High concentrations can trigger burning eyes, headaches, and nausea, particularly among children, seniors, and pregnant individuals.
When do Philippine local government units (LGUs) suspend classes for vog?
LGUs in Batangas, Cavite, Laguna, and Metro Manila typically declare class suspensions when air quality drops into the Unhealthy or Very Unhealthy categories (AQI 151+), or when PHIVOLCS records elevated SO2 flux combined with thermal wind inversion that traps vog close to ground level.
What type of mask provides the best protection against vog?
The Department of Health (DOH) recommends well-fitted N95, KN95, or KF94 respirator masks to filter out acidic fine aerosol particles. Standard cloth masks do not block volcanic sulfur gas or fine PM2.5 particles effectively.
