Acids and bases in natural water; alkalinity, pH and buffer capacity - Eutrophication - Effects in running waters
3 important questions on Acids and bases in natural water; alkalinity, pH and buffer capacity - Eutrophication - Effects in running waters
What are the main primary producers in running waters?
Ditches, streams and (small) rivers: water plants (macrophytes).
What is the good ecological quality characterized by in running waters?
Large diversity of aquatic vegetation species and fauna related to it.
What are the problems of eutrophicated running water types?
-increase of nutrient loading leads to shift in vegetation species composition
-deteriaration ecological quality
-macrophyte species will be dominated by a (or a few) fast grwoing species like waterweed (Elodea)
-dissapearance of all the submerged macrophytes and floating species like duckweeds (Lemna) will take over
