Question

Which of the following is not a main cause of pollution in rivers like the Ganga ?

• A. Industries dumping wastes into rivers
• B. Releasing untreated sewage into rivers
• C. Pesticide and fertilizer run off from farms
• D. All of the above

Answer 1

The correct option is D

All of the above

Pollution in rivers is primarily caused by:

• The release of waste chemicals and raw untreated sewage into rivers.
• Fertilisers and pesticides when used in excess can seep into our waterways, making them uninhabitable for the aquatic creature to live in.

Usage of leaded petrol primarily causes air pollution leading to various health hazards such as high blood pressure, brain damage, etc. It is a serious cause of air pollution and not water pollution.
