Effect of water pollution

EFFECT OF WATER POLLUTION
  • Oxygen Depletion
    • Due to organic compounds overloading the chemical oxygen demand (COD) increases. Consequently, the water contains less amount of oxygen to breach the living forms in water. This leads to death of many life forms to low dissolved oxygen (DO).
  • Nitrogenous and Phosphorous Compound
    • The nutrients nitrogen and phosphorous promotes the growth of algae which prevents other plant’s prosperity.
  • Pathogens
    • Water pollutants invariably encourage the ideal condition growth and proliferation of disease causing microorganism (pathogens). This spreads diseases like cholera, flu, etc.
  • Toxic Compounds
    • Heavy metals, pesticides, cyanides, lead, mercury, dyes, etc, are the ingredients of many industrial effluents discharged in water.
