IA2017 – Eutrophication is still a problem in some areas
18th September 2017 by Marine Scotland Communications
Eutrophication is the result of excessive enrichment of water with nutrients. This can cause accelerated growth of algae (phytoplankton) and plants. This may result in an undesirable disturbance to the balance of organisms present and ultimately to a decline in the overall water quality. Eutrophication is not always a local problem. Water masses continuously move...
