Explanation

By removing sulphur from petrol and diesel, the emission of `SO_(2)` can be reduced in exhaust.` SO_(2)` is a very harmful air pollutant. It can damage the vegetation by causing chlorosis. It can cause acid rain (by forming `H_(2)SO_(3)` and `H_(2)SO_(4))`, damaging buildings and plants. In human beings it causes irritation in eyes and damage to respiratory system (e.g., bronchitis).
