Answer:

Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.

The contamination of the water bodies due to pollutants is called water pollution. It can be caused due to non-chemical pollutants, like salt and sediments.

What are non-chemical pollutants?

Non-chemical pollutants are the substances that contaminate and degrade the water quality but are not have a chemical composition and elements that are harmful.

Non-chemical sources are salt from irrigation lands, and sediments from the rocks that travel down the surfaces and reach the water body to contaminate them.

Therefore, salts and sediments are non-chemical pollutants.
