Acids and bases in natural water; alkalinity, pH and buffer capacity - Eutrophication - Effects in lakes
3 important questions on Acids and bases in natural water; alkalinity, pH and buffer capacity - Eutrophication - Effects in lakes
What is/are major problem(s) of eutrophicated lakes?
Primary production by algae and the subsequent decay of organic matter. See equation: the production and respiration of algae.![]()
How does a lake with a good ecosystem state and good quality look like?
A lake with clear water and rich submerged vegetation
What does the lake look like at different nutrient loads?
Higher nutrient loads mostly have a negative effect on the state of the ecosystem.
Low nutrient load: clear water, low biomass / high diversity of aquatic plants, low phytoplankton (nutrient limited)
Medium nutrient load: clear water, high biomass / low to moderate diversity of aquatic plants, low pytoplankton (grazer controlled) to high (N or P limited)
High nutrient load: turbid water, no aquatic plants, high cyanophyte rich (phytoplankton), grazer resistant phytoplankton (CO2 limited)
