Understanding the health hazards of volcanic ashfall

Mount Kanlaon, one of the 24 active volcanoes in the Philippines erupted and spewed a  voluminous ash column up to 3,000 meters on December 09. The second eruption of  Kanlaon this year, the volcano in Negros released 4,638 tons of sulfur dioxide prior to its  eruption. 

Sitting on the Pacific “Ring of Fire,” The Philippines is no stranger to volcanic activity. Another active volcano, the Taal volcano has recorded at least 38 eruptions in the last  450 years. The 2020 major eruption of Taal volcano blasted heavy ashfall into the air,  which reportedly reached as far as Metro Manila, Calabarzon, and Central Luzon. The  Department of Health has continuously warned the public about the health risks that are  associated with ashfall. 

In light of recent events, Barangay BK, an online health platform with an advocacy to  inform and educate about medical issues and concerns of interest to Filipinos breaks  down the health risks of volcanic smog and ashfall on Bell-Kenz Pharma Facebook  page  

According to Dr. Johnson See, a medical specialist on Adult Pulmonary and Critical  Care, inhalation of ash can cause nasal irritation and discharge, sore throat, coughing,  wheezing, and breathing difficulties, especially among children, the elderly, and people  with asthma. The featured medical expert on Barangay BK’s Breaking News, Dr. See  

cites long term exposure to volcanic ashes is linked to other health issues such as  bronchitis, Chronic Obstructive Pulmonary Disease, and other respiratory disorders.  

Volcanic particles have health risks on the eyes according to the Department of Health.  Common eye concerns include irritation, acute conjunctivities, and corneal abrasion.  Volcanic ash can trigger reddening, skin irritation, and secondary infections due to  scratching.  

Dr. See advises individuals with pre-existing pulmonary conditions like asthma, bronchitis, and emphysema to take extra precaution measures and avoid exposure to  the ash particles. Staying indoors, closing the doors and windows, and putting damp  towels at thresholds can minimize exposure to ash particles. Adjust air conditioners and  air purifiers on the recirculation settings to prevent outside air from entering the room,  and circulate clear air in your homes.

If adults have to go outside, wearing respiratory protection such as medical or surgical  masks, goggles, eyeglasses, or wet handkerchiefs can reduce the chances of exposing  oneself to ashfall. Hydrate, and drink plenty of fluids to ease throat and nasal irritation.  Keep medications handy such as asthma inhalers, and COPD medicines. 

Monitor the news, remain vigilant and prepare your emergency bag for necessary  evacuation. And if you are experiencing discomfort while breathing, or bronchitis-like  illnesses, seek immediate medical attention.
