Sulfur dioxide is released into the air through volcanic eruptions and lava and can cause acid rain downwind of a volcano, according to the United States Geological Survey (USGS).

When active, Kīlauea pumps out thousands of tons of volcanic gases, namely water vapor, sulfur dioxide, and carbon dioxide.

Acid rain aside, there are much bigger risks on the Big Island right now, says Jacob, including the very high concentration of sulfur dioxide gas in the air. “SO2 exposure is not good for ...

Only deeper reductions in nitrogen oxide and sulfur dioxide emissions -- the pollutants which cause acid rain -- are likely to help the Northeast recover, scientists said in the report released ...

Acid rain is primarily caused when sulfur dioxide, released into the air by the burning of coal, high-sulfur oil, and smelting and refining of metals, interacts with rain or fog.

The amount of acid rain depends on the concentration of sulfur dioxide in the air, CNN's Guy says. Determining how acid rain affects human health is complicated, and Guy says the effects on the ...
