What are the harmful effects of water pollution on the aquatic ecosystem?

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

How does water pollution affect aquatic ecosystem?

Harm to any of these organisms can create a chain effect, imperiling entire aquatic environments. When water pollution causes an algal bloom in a lake or marine environment, the proliferation of newly introduced nutrients stimulates plant and algae growth, which in turn reduces oxygen levels in the water.

What are the harmful effects of water pollution?

EFFECTS OF WATER POLLUTION

This can cause fish and other aquatic organisms to die. Toxic elements dissolved in water can make their way to humans through fish or other aquatic organisms. Water pollution also leaches chemicals into the soil that may impact the growth of plants or other food crops.

What are the types and effects of water pollution?

Oxygen depletion pollution

They use up all the oxygen in the water. The depletion of oxygen leads to the death of aerobic microorganisms but promotes the thriving of anaerobic organisms. Certain anaerobic microorganisms contaminate the water by producing toxins such as sulphides and ammonia.

What is water pollution causes and effects?

Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste, petroleum, and disease-causing microorganisms.
