Summary

[edit]
Description
  • English: Eutrophication is caused by the enrichment of an ecosystem with chemical nutrients, typically compounds containing nitrogen or phosphorus, here in a pond, with many dead leaves., under tree, in Lille (North of France). This sort of eutrophication is not abnormal if just for some days or weeks.
  • Français : L'eutrophisation est la modification et la dégradation d'un milieu aquatique, lié en général à un apport excessif de substances nutritives (azote provenant surtout des nitrates agricoles et des eaux usées, et secondairement de la pollution automobile, et phosphore, provenant surtout des phosphates et des eaux usées). Ce type d'eutrophisation n'est pas anormale dans les milieux eutrophes lors d'une période très chaude et si elle dûre seulement quelques jours. (Lille, Bois de la citadelle, nord de la France).
