Title: Eutrophication


1
Eutrophication
  • The facts

2
What is Eutrophication you ask?
  • Eutrophication is when waterways, which are
    naturally low in nutrients such as phosphates and
    nitrates, are polluted with fertiliser run-off
    containing these nutrients.

3
What are the effects of Eutrophication?
  • Water plants reatly increase in biomass with the
    due to the increase in nutrients in the water.
  • This causes the death of other, smaller plants
    which are covered by these plants, increasing the
    amount of dead matter in the water.
  • Bacteria use the dead matter to respire, thereby
    using oxygen from the water.
  • Lack of oxygen leads to the death of sensitive
    organisms unable to carry out gas exchange

4
But what can I do to prevent Eutrophication from
happening?
  • Laws regulating the discharge and treatment of
    sewage
  • Riparian buffer zones an area of sediment
    between water and land to prevent Eutrophication
  • Nitrogen testing soil is tested for nitrogen
    content, allowing bare minimum necessary Nitrogen
    to be used.
  • Phosphorus removal measures (as used in Finland)
