(HealthDay News) -- Major volcanic eruptions like the one going on in Hawaii are rare, but they can lead to serious health concerns.
Volcanos produce gases mixed with water and tiny particles that form a type of pollution called vog. It can irritate the eyes and trigger heart attacks and respiratory problems such as asthma and wheezing.
Active volcanos also spew ash, which can lead to symptoms such as coughing, chest tightness and wheezing.
The American Lung Association suggests ways to deal with vog or ash:
