Sulfur dioxide is one of a group of highly reactive gasses known as “oxides of sulfur.” The largest sources of SO2 emissions are from power plants. When sulfur dioxide combines with water, it forms sulfuric acid, which is the main component of acid rain.

Chemical contamination

Sulfur dioxide can affect the respiratory system, the functions of the lungs and irritate our eyes. When sulfur dioxide irritates the respiratory tract it causes coughing, mucus secretion, aggravates conditions such as asthma and chronic bronchitis and makes people more prone to respiratory tract infections.

Factoids [2]

Car exhausts contribute 3 percent of the total sulphur dioxide gas in the air.

Sulfur dioxide is sometimes used as a preservative for dried apricots and other dried fruits owing to its antimicrobial properties, and it is sometimes called E220 when used in this way. As a preservative, it maintains the appearance of the fruit and prevents rotting.
