Explanation

Sulphur dioxide is produced when sulfur impurities present in coal and diesel burn during combustion. It is a suffocating gas that causes respiratory distress and is also corrosive as it dissolves in moisture to form sulphurous/sulphuric acid, irritating and damaging respiratory tissues and eyes.
