Transcript of "Water pollution (Sociology)"

  1. 1. WATER POLLUTION • Greatest cause of human disease • Any physical, biological, chemical change in water quality • Water becomes unsuitable for use • Global water scarcity • Earth – 20% area land, 80% area water • Man consumes 2 liters water every day
  2. 2. • Body weight – more than 80% by water • Water as natural resource limited • 70% of water in India polluted • Water is never pure in chemical sense • Chief water pollutants – oxygen demanding wastes, disease causing agents, radio-active wastes, thermal discharges
  3. 3. Sources of water pollution • Point and non-point sources
  4. 4. Point Sources • Factories, power plant, sewage treatment plant, underground coal mines, oil wells
  5. 5. Non-point sources • Farm fields, lawns, gardens, construction sites, agricultural chemicals, industries
  6. 6. Other Sources • Industrial effluents, agricultural dischargers, oils, plastics, metallic wastes, acids, insecticides, fertilizers, pesticides, chemicals, wastes pumped into rivers, lakes streams.
  7. 7. Water Quality • Oxygen dissolved in water • Water with oxygen content support aquatic life • Oxygen level reduced, when sewage wastes discharged in water • Human activities introduce toxic, inorganic chemicals into water • Inorganic chemicals pollute water • The chemicals are heavy metals such as mercury, lead, tin.
  8. 8. Water Pollution • Water contaminated by sewage, chemicals, effluents of water from factories, automobiles, flow in river waters, well waters. • Three sources – sewage, industrial waste, agricultural waste • Rivers are dumping grounds for poisonous substances, insecticides and acids
  9. 9. • Polluted water cause damage to human beings, cattle, fish, plants, trees etc. • It causes diseases like cholera, typhoid, dysentery, jaundice, viral diseases.
