Which of the following best describes sewage, fertilisers, and industrial effluents discharged into rivers?
Water pollutants
Sewage, fertiliser runoff, and industrial effluents, when discharged directly into rivers, introduce harmful chemicals, excess nutrients, and pathogens into the water body.
These contaminants degrade water quality, cause eutrophication, and harm aquatic life and human users of the water, making them water pollutants rather than merely biodegradable waste, soil nutrients, or air pollutants.
Hence, such discharges are best described as water pollutants.
