What about the Vog?
Vog is created when volcanic gases (specifically oxides of nitrogen) react with sunlight, oxygen and moisture. It is made up of a mixture of gases and aerosols, which makes it hard to study and potentially more dangerous than either on their own. Although vog has not been as extensively studied as it could be, it has been found that most of the aerosols are acidic and of a size where they can remain in the lungs where they can damage the lungs and impair function. People who have been exposed to vog report headaches, breathing difficulties (including inducing asthma attacks), flu-like symptoms, and general lethargy. These effects are especially pronounced with children. Most studies of vog have been in areas where vog is present, and not of the effects of vog itself (in controlled conditions).
