0 the addition of nutrients to water in lakes and rivers, which encourages plant growth that can take oxygen from the water and kill fish and other animals: --
Massive use of fertilizers contributes to the eutrophication of rivers and lakes.
These surveys have shown that evidence of eutrophication is confined to a handful of small, localised inshore locations.
However, nitrate as a cause of eutrophication is not insignificant.
However, as the committee has rightly pointed out, the causes of eutrophication are complex and other factors, such as phosphate, may also be limiting agents.
An ideal site for eutrophication would be created.
Where eutrophication has already damaged the aquatic ecosystem, there should also be an accompanying commitment to the restoration of those important natural waters.
In an ideal environment there is always a danger of eutrophication.
Designation requires phosphorus removal from sewage treatment works into the affected waters to combat eutrophication.
In hot summers, there will be problems of eutrophication.
