Sulfur dioxide is a gas consisting of oxygen and sulfur. It is produced in natural phenomena such as volcanic eruptions and also as a result of various industrial activities. The gas irritates the lungs and has a smell reminiscent of rotting eggs. The presence of sulfur dioxide in the air has negative health impacts and the production of acid rain as a result of the presence of the gas in the atmosphere has contributed to environmental degradation. Industrial processes release sulfur dioxide into the air and produce acid rain in remote locations, owing to atmospheric circulation.
