    Microorganism & Water Pollution - Presentation Transcript

    1. MICROORGANISMS & WATER POLLUTION MAJID MOHIUDDIN
      • IMPORTANCE:
      • Every thing originated in the water & everything is sustained by water.
      • All life on earth depends on water.
      • Man uses water for many purposes.
      • - drinking
      • - irrigation
      • - fisheries
      • - industrial processes
      • - transportation
      • - waste disposal
      • IMPORTANCE OF WATER
      • For life
      • Inorganic constituent of living matter.
      • Medium for Growth:
      • Second natural medium
      • Contain mineral nutrients and dissolved oxygen.
      • Organic matter = Microbial Population.
      • Microbial population higher in Rivers near thickly populated cities than village.
      • PH, Temperature range & inorganic phosphate & situation of the lake.
      • Availability of possible factors (Zinc & Coppers)- limits growth of Microbes. & Poor quantity of nitrate and nitrogen.
      • Calcium-harmful for algae.
      • Water in Nature
      • Water exist in 3 states
      Gas Solid Liquid Lithosphere Atmosphere Hydrosphere
    2. Ocean Polar Ice Caps Glaciers Ice fields Inland surface water – Lakes and River
    3. Ocean – 97% of the Hydrosphere .
    4. Polar ice caps Ice fields Glaciers 2% in the form of ice
    5. Inland surface water 0.02% Lake River
      • TYPES OF WATER
      • Atmospheric water: Rain water & Snow water (dust, soot & suspended particles & Air borne bacteria)
      • Surface water: Mountain, river water also. (organic matter, Soil microflora). Saprophytic Spp. & Protozoa .
      • Ground water: Water percolates (few bacteria & little amount of organic matter). (Microbes cannot multiply)
      • Stored water: Pounds, Reservoirs, Lakes & Ocean.
              • Microbial Population decreases
              • X Area
              • X Types of vegetation
              • X Seasons
              • X Individual chemical components
              • X Total inorganic Salt contents.
              • Protozoa Presents.
    6. Atmospheric water Rain water & Snow water (dust, soot & suspended particles & Air borne bacteria)
    7. Surface water: Mountain, river water also. (organic matter, Soil microflora). Saprophytic Spp. & Protozoa . Mountain water River water
    8. Ground water: Water percolates (few bacteria & little amount of organic matter). (Microbes cannot multiply)
    9. Stored water Pond Reservoirs Lakes Ocean
      • Classified Based on Suitability for support of living matter.
      • Stored Water:
      • Eutrophic Lake: Well nourished
      • Oligotrophic Lake: Poorly nourished
      • Dystrophic Lake: High Organic matter of special type – Lake dark and acidic.
      • Classified Based on Suitability for support of living matter.
      • Stored Water:

      • Stored Water:
      • 3.Dystrophic Lake: High Organic matter of special type – Lake dark and acidic.
      • Water Impurities
      • Sea water ( about 3% dissolved mineral impurities)
      • Connote water (Produced with some crude oils, sometimes 20 to 30% dissolved salts)
      • Brackish water ( Industrial waste water)
      • Measured in Parts Per Million (ppm)
      • - 10,000 ppm = 0.015%

      • 3. Periphyton (Biotecton)
      • are the organisms (both plant and animal) attached or clinging to the submerged plant or other surfaces projecting above the bottom
      • An organism may remain as periphyton throughout its life or during some period of its life cycle.
      • Animals may be an obligatory or a facultative periphyton.
    10. Periphytons
      • 4. Benthios (Zoobenthos)

      • mud water.
      • Saprophytism
        • Pleosaprophytic Zone: Heavily Polluted Zone of water reservoir and contains sufficient amount of Organic residues of plants and animals.
        • Mesosaprophytic Zone: Less polluted due to high rate of mineralisation and oxidation of organic matter.
        • Oligosaphrophytic zone: pure and clear water
      • Microorganisms in sea:

      • WATER POLLUTION
      • Change in quality or composition
      • By Waste disposal and other human activities
      • Less suitable or Harmful for drinking, domestic, agricultural recreational, fisheries or other purposes.
      • Water Pollution: The adding to water of any substance, or the changing of water’s physical and chemical characteristics in any way which interferes with its use for legitimate purpose.
      • It contain impurities of various kinds- both dissolved and suspended
