Freshwater ecosystem improper operation

ALGAE BLOOM !!!

Turbidity increases Oxygen decreases Anaerobic process: malodorous gases Accumulation of reduced substances

(sulphides, ammonium, Fe, Mg...)

DECREASING WATER QUALITY:

Loss of natural balance between input nutrients and algae

Algal bloom

Relationship between nutrients and the algal community weight:

1P: 7N: 40C: 100 g dry weight: 500 g wet weight

(Vallentyne, 1978)

1 gram of phosphorus can produce up 500 grams of algal biomass
