Blue-green algae observations in lakes and coastal areas have increased slightly since last week, said Finnish Environment Institute (SYKE) in a press release on Thursday.

However, the situation is normal for the season and, in lakes, even better than usual.

In sea areas, blue-green algae close to the surface have been observed mainly in the eastern parts of the Gulf of Finland. Elsewhere in the open sea, blue-green algae are mixed with water.

SYKE observes the cyanobacteria occurrence as part of the monitoring of the state of the environment in Finland.

The national cyanobacterial monitoring is carried out as part of the monitoring of the state of the environment in cooperation with the Centres for Economic Development, Transport and the Environment, municipal environmental and health authorities, and the SYKE. Finnish Rotary Clubs are also actively involved in nationwide cyanobacterial monitoring.

The cyanobacterial monitoring is based on the monitoring of cyanobacterial deposits in surface water. The intention is to provide an overview of the cyanobacterial situation in different water bodies.

The monitoring includes about 400 permanent observation sites across the country on inland and coastal waters and in the archipelago.
