What is Eutrophication?
Eutrophication is when excessive nitrogen and phosphorous. Lakes are suffocated by plant growth and oxygen depletion would kill many animals living in that habitat. The algal bloom covers the water surface leaving no room for the sun to shine through, thus no photosynthesis.
What are the effects?
Environmental Impact
Plant and animal biomass increase
Pollution Algae outweighs clean water algae
Water losing transparency
Reduce water clarity
Impede water flow and navigation
Anoxic conditions
Human Impact
Taste or Odor in water; Injurious to health (to animals as well)
Fish farms are effected
Sewage
Harmful water quality
Where does this come from?
Drainage water and run offs (mostly partaking in fertilizers)
What are the causes?
Main cause: excessive nitrogen and phosphorous
Rate of sedimentation
Degradation of water
Human activity: Fertilized nitrogen compounds from agricultural lands; loss from atmospheric deposition
Human waste, Nitrate and Phosphates
Long term effects ?
The obvious long term effect of eutrophication is the algal blooms. When an algal blooms, the stream, river, lake or ocean becomes completely covered with algae, and most of the time is bright green substance with a gooey texture . Other than the fact that it is very ugly , eutrophication the algae blocks the sun from hitting the plants and fish in the water, this prevents the plants from photosynthesizing, this process has produces oxygen for marine life, like fish and crabs.
