Domestic pollutants are from noncommercial, everyday activities such as what?

• A. Industrial pollutants from factories.
• B. Noncommercial everyday waste such as human sewage or greywater.
• C. Pesticide residues from agriculture.
• D. Sediment from construction sites.

Answer: (B)

Domestic pollutants come from noncommercial, everyday activities inside homes. A clear example is human sewage or greywater, which is wastewater from sinks, showers, laundry, and toilets. These wastes bring organic matter, nutrients, and microbes into water bodies, and if released untreated they can deplete oxygen and pose health risks to both ecosystems and people. The other options point to pollution from industrial or agricultural activities, not daily household waste. So human sewage or greywater best illustrates domestic pollutants.
