The major feature of the lake ontario eutrophication model (which used the eutrophication kinetic structure known as lake 1) that differed from the lake erie model was the incorporation of vertical segmentation to represent the epilimnion and hypolimnion of the lake. Eutrophication eutrophication is the process by which a body of water becomes enriched in dissolved nutrients (as phosphates), stimulating the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen. Eutrophication can have serious, long-term effects the most notable effect of eutrophication is algal blooms when a bloom occurs, the stream, river, lake or ocean becomes covered with algae.
Introduction eutrophication is the direct result of non-point nutrient pollution, specifically phosphorous, in freshwater sources that leads to excessive algal growth, and lowers overall water clarity and quality (kung 1991.

Eutrophication can also lead to hypoxia, or low dissolved oxygen concentrations, leading to fish kills and decreased biodiversity adverse impacts from nitrogen and phosphorus pollution occur in 65% of the nation’s major estuaries (bricker et al 2007) and there are 166 coastal hypoxic dead zones in the us (diaz and rosenberg 2008.

An integrated approach to eutrophication abridged version- a student's guide today, more and more freshwater bodies have become polluted by nutrients originating from agricultural, domestic and industrial sources.
Introduction eutrophication is generally understood to refer to enrichment of biological systems by nutrient elements, notably nitrogen and phosphorus, and to the enhanced production of algal and higher. Introduction phase 4: laboratory analysis i'll go into this more in the background section, but basically eutrophication is a process that causes algal blooms and possibly even dead zones in waterways associated with these algal blooms these blooms can kill fish and other organisms that inhabit these waters, and. Human-induced eutrophication is occurring throughout the world eutrophication reduces water quality and alters ecological structure and function of freshwaters biological impacts of eutrophication are well understood, however degree and costs are not.
