Question

It is environmentally important to use unleaded petrol over leaded petrol.

• A. True
• B. False

Answer 1

The correct option is A True

Leaded petrol upon combustion emits more harmful gases into the atmosphere which contains lead as one of their constituents.
It contaminates air, dust, soil, drinking water and food crops. The excessive exposure to lead may cause a permanent loss of intelligence and disruption of behaviour. So, it is important to avoid this and use unleaded petrol.
