Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sulfur dioxide is a major air pollutant and has significant impacts upon human health. In addition, the concentration of sulfur dioxide in the atmosphere can influence the habitat suitability for plant communities, as well as animal life. Sulfur can also be removed from fuels before burning, preventing formation of $SO _2$ when the fuel is burnt. The Claus process is used in refineries to produce sulfur as a byproduct.
