| This can have a big effect, especially upon the situation regarding eutrophication and lack of oxygen in the Baltic. |
| A five-year research program will address the role of nitrogen in acidification and eutrophication. |
| In addition, samples are taken for research concerning eutrophication and algal blooms. |
| Particular attention is therefore given to the impact of excess nutrients in the Baltic Sea itself leading to eutrophication and algal blooms. |
| At present, the most common and serious anthropogenic perturbation of lakes is eutrophication due to increased nutrient availability. |
| Major environmental issues in the Narva River and Lake Peipsi basin are water eutrophication and management of the lake's fish resources. |
