Following are the effects of Water Pollution

Pollutant                                 Effects

1. Heavy metals: These are toxic to marine life such as fish and subsequently to the humans who eat them. Heavy metals can slow development; result in birth defects and some are carcinogenic. 

2. Microbial pollutants: Often result in infectious diseases that infect aquatic life and terrestrial life through drinking water. Microbial water pollution is a major problem in the developing world, with diseases such as cholera and typhoid fever being the primary cause of infant mortality.

3. Organic matter and nutrients: Cause an increase in aerobic algae and depletes oxygen from the water column. This causes the suffocation of fish and other aquatic organisms.

4. Sulfate particles: From acid rain can cause harm the health of marine life in the rivers and lakes it contaminates, and can result in mortality.

5. Suspended particles in freshwater: Reduce the quality of drinking water for humans and the aquatic environment for marine life. Suspended particles can often reduce the amount of sunlight penetrating the water, disrupting the growth of photosynthetic plants and micro-organisms.
