Dust and other particles from volcanic eruptions do have potential negative effects on human respiratory tracts. When a volcano erupts, large amounts of ash, gas and particulate matter are released into the atmosphere. Some of this material can make up volcanic ash, which is fine-grained material made up of tiny shards of glass, minerals and other compounds.
The effects of volcanic ash on the respiratory system depend on several factors, including the particle size and concentration of the dust, as well as the exposure time and health of the individual. Here are some of the major health risks:
Respiratory Irritation and Illness: Inhaling volcanic ash may cause throat irritation, coughing, difficulty breathing, and exacerbation of asthma symptoms. Long-term exposure may also increase the risk of chronic respiratory disease.
Eye problems: Fine particles in volcanic ash can irritate the eyes, causing pain, redness, conjunctivitis and blurred vision.
Skin problems: Volcanic ash can cause dry skin, itching and rashes.
To protect the respiratory tract from the effects of volcanic ash, recommended protective measures include wearing a dust mask, keeping indoor air clean, avoiding unnecessary outdoor activities, and using an air purifier. These protective measures are especially important for people with pre-existing respiratory conditions.
