Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfuric acid is a major component of acid rain. Acid rain can damage forests and crops, change the acidity of soils, and make lakes and streams acidic and unsuitable for fish.
The gas is also a lung irritant. The EPA regulates sulfur dioxide emissions along with five other so-called criteria pollutants, including lead and carbon monoxide. Who knew? Sulfur makes up almost 3 percent of the Earth's mass, according to Chemicool. That is enough sulfur to make two additional moons. Sulfur (as sulfur dioxide) has been used to preserve wine for millennia, and remains an ingredient in wine today, according to the Practical Winery & Vineyard Journal. It's not clear where the name sulfur comes from.
