volcanic gases
Eruption's toxic breath
Volcanic gases are the gases released during volcanic eruptions or emitted continuously from volcanic vents and hot springs.
The mixture typically includes water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide, among others.
These emissions can affect climate, create acid rain, and pose health hazards near active volcanic sites: Scientists monitored volcanic gases for signs of an impending eruption.
