4. EFFECT OF WATER POLLUTION
Organic rubbish causes the decreasing of oxygen dissolved.
Anorganic rubbish cause sunray blocked & obstructs photosynthesis
Detergent and the overuse of fertilizer causes eutrofication.
If pesticide waste gets involved in food chain, its concentration will be higher and higher.

8. EFFECT OF WATER POLLUTION
Industrial wastes contain “B3 waste”
Dangerous metals, suck as mercury from metal industry, plastics, can cause acute damage of kidneys.
Mining wastes are usually polluted by sulfate acid and steels and it can cause hard water.
