Sulphur dioxide

英文Sulphur dioxide

中文 (征集中)


This smelly substance, a gas with the distinctive odor of rotten eggs, is produced as a byproduct of burning sulphur-containing fossil fuels such as coal and natural gas. This substance changes into highly corrosive sulphuric acid when exposed to water vapor suspended in the air, and when it falls back to earth as acid rain, it can cause significant damage to virtually everything in the environment. Most airborne sulphur dioxide is produced by coal-fired generating plants
