Explanation

Gases from household materials are not a direct cause of water pollution.

Water pollution is typically caused by the release of harmful substances into water bodies, such as:

• Sewage water from homes (containing human waste, chemicals, and other pollutants)
• Untreated water from industries (containing industrial chemicals, heavy metals, and other pollutants)
• Water runoff from agriculture (containing pesticides, fertilizers, and other pollutants)
