Wastewater treatment boom changes nutrient balance in lakes A vast number of new wastewater treatment plants in developing countries has led to an imbalance between phosphorous and nitrogen in surface waters. The result could be excessive growth of potentially poisonous algae with a preference for nitrogen. A new study calls for better nutrient reduction in order to maintain ecosystem biodiversity.
Microplastics found in 4 of 5 bivalve species investigated in Nordic waters A new research project has looked at microplastics in marine bivalves from 100 sites spread throughout much of the Nordic waters. Microplastics were found in 4 of the 5 bivalve species investigated, and there was a huge variation in the occurrence and type of microplastics.

News Article 25.06.2020 FISHTREAT™: A novel, sustainable medicinal dosing system for fish farms Researchers at the Norwegian Institute for Water Research (NIVA) have developed a new dosing system for continual treatment of salmon lice directly in cages. The overall impact to the environment is expected to be minimal and the fish are relieved of the stress associated with handling during treatments.
Publication 09.07.2020 Ocean Acidification and Human Health While ocean acidification was initially perceived as a threat only to the marine realm, the authors of a new publication argue that it is also an emerging human health issue.
Publication 16.06.2020 Need for better approaches to tackle multiple stressors in European lakes and rivers A newly released Nature paper with several NIVA co-authors highlights a continued management need for reduction of nutrient stress in lakes. It also shows that river management requires more complicated approaches to tackle several stressors simultaneously.
