eutrophication

 [u″tro-fĭ-ka´shun]
the accidental or deliberate promotion of excessive growth (multiplication) of one kind of organism to the disadvantage of other organisms in the same ecosystem.

eutrophication

(ū-trŏf″ĭ-kā′shŭn) [Gr. eutrophein, to thrive]
Alteration of the environment by increasing the nutrients required by one species to the disadvantage of other species in the ecosystem, esp. in an aquatic environment.

eutrophication

a process by which pollutants cause a body of water to become over-rich in organic and mineral nutrients, so that algae, CYANOBACTERIA and other microorganisms grow rapidly and deplete the oxygen supply.

eutrophication

the accidental or deliberate promotion of excessive growth (multiplication) of one kind of organism to the disadvantage of other organisms in the same ecosystem.

2009) was applied in this study to assess the impact in four different categories: i) global warming potential, ii) marine water eutrophication, iii) freshwater eutrophication, and iv) fossil fuel depletion.

Knowledge of the spatial and temporal distributions of estuarine phytoplankton offers insights into the potential effects of eutrophication and provides a tool for establishing relevant management strategies (Conley 2000; Olsen et al.
03 mg/L is commonly used as a lower level at which algal growth and eutrophication occur (SPEA 2006).
In this study, five impact categories relevant to the defined study objective were taken into consideration, including global warming, acidification, eutrophication, nonrenewable resources depletion, and human toxicity.

Nitrogen- and phosphorus-driven freshwater and marine eutrophication has major socioeconomic consequences that include lost livelihoods, reduced property values, damage to fisheries, loss of recreational opportunities, and several health risks.
However, where the combination of nitrogen and phosphorous supply to waterways is very high, as in rich agricultural areas, the receiving rivers, lakes, and estuaries exhibit extreme eutrophication.
Eutrophication is the enrichment of an ecosystem with chemical nutrients, typically nitrogen, phosphorus or both.
The relationship between the metrics and selected eutrophication variables was documented in the Gulf of Finland, Gulf of Riga, and Western Archipelago.
Eutrophication is the ecosystem's response to the addition of artificial or natural substances, mainly phosphates, through detergents, fertilisers, or sewage, to an aquatic system.
The project also plans to investigate the causes of the increase of jellyfish populations such as the introduction of non-indigenous species, construction of breakwaters, which constitute the necessary substrate for the development of polyps (sessile stage of jellyfish life cycle), overfishing and eutrophication.
