Algal blooms

Algal blooms are rapid and excessive growth of algae in aquatic environments. These blooms can produce toxins that contaminate water sources and threaten aquatic life and humans. Understanding the causes, consequences and responses to algal blooms is essential to protect ecosystems and communities that rely on water sources.

Wastewater treatment boom changes essential 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.

BEDREVANN

In the BEDREVANN project, we will study the impact of cyanotoxin-contaminated irrigation water in agriculture and the risk to food producers and end users with Akersvannet in Vestfold as a pilot area. Akersvannet is a highly nutrient-rich lake with annual blooms of toxin-producing cyanobacteria. Water from the lake is used to irrigate surrounding agricultural areas where vegetables are largely grown, and this can pose a risk to safe food production.
