eutrophication
eutrophication Process by which a stream or lake becomes rich in inorganic nutrients by agricultural run-off or other artificial means. Compounds of nitrogen, phosphorus, iron, sulphur and potassium are vital for plant growth in water; in excess they overstimulate the growth of surface
algae or
cyanobacteria producing
bloom that can consume all available dissolved oxygen with devastating effects on marine life.
