In quite waters, such as lake and lagoons, aquatic vegetation proliferate due to nutritious elements such as nitrates and phosphates that act as fertilizers . The principal source of nutrients are the black waters and agricultural drainage that originate massive growth of algae , which generate great quantities of vegetable mass on the waters and its further accumulations on the lake sides
The problems originate when man contaminate the lakes and rivers with excess nutrients that accelerate the process of eutrophication, that cause the accelerated process of growth
of algae , the death of fish and the rest of the aquatic fauna and flora, generating anaerobic conditions.
During warm times the overcharge of these chemical products that serve as nutrients , generate the accelerated growth of vegetation , sucxh as, algae, cianobacteria, aquatic lentils , which when they die, and decomposed by aerobic bacteria provoke the depletion of dissolved oxygen in the vegetable layer of the water and cause the death of different types of aquatic organisms that consume oxygen , the river and lake waters. An eutrophic lake, is such of low depth and poor dissolved oxygen content but rich in nutritive materials and organic matter.
-Considerable increase of Phytoplankton. The green blue algae that develop
spectacularly, while other types, disappear.
-Bacterial activity increases (ANAEROBIC)
- Aquatic animals get sick and die
all organisms are dead.
-There is a significant elevation of BOD.
-The concentration of nitrogenous compounds and phosphates increases, as well as those of other chemical elements
