Any factor that causes increased nutrient concentrations can potentially lead to eutrophication.

The external nutrient concentrations are extremely important to proceeding through the Start checkpoint.

At the same time a different study found high nutrient concentrations linked to sewage effluents.

As already mentioned, the deep-water aeration can reduce nutrient concentrations significantly.

A wide range of turbidities and nutrient concentrations can be tolerated.

They noted that the nutrient concentrations were much higher deeper in the ocean, where it's too dark for photosynthesis to take place.

However, long-term nutrient concentrations show a high inter-annual variability and have declined during recent years.

Mineral nutrient concentration in roots may be 10,000 times more than in surrounding soil.

The lake body generally has low nutrient concentrations, good water clarity and excellent dissolved oxygen levels.

The distribution of individual species of fen plants is often closely connected to water regimes and nutrient concentrations.
