pollutants of water give 2 wards example​

Answer 1

Answer:

Pathogens, Inorganic Material

Explanation:

Pathogens can be bacteria, protozoa or viruses. Bacteria, for example, are commonly found in water; it is when they start to increase in numbers that are above safe levels that water contamination occurs.

Inorganic materials — in particular heavy metals like arsenic, mercury, copper, chromium, zinc and barium — though harmless in very small concentrations, act as pollutants when they end up concentrated in water.

A second category of water pollutants is oxygen-demanding wastes; wastes that can be decomposed by oxygen-requiring bacteria.
