Press releases

In both sea areas and lakes cyanobacteria has been observed more than during the last week. Although, when comparing this week to the previous summers’ same period of times, the cyanobacteria occurrences have been still reported less than usual. The cyanobacteria blooms are typically as their strongest in late July and early August.

The load of active pharmaceutical ingredients released into the environment can be reduced by treating waste water at primary sources, such as hospitals, healthcare institutes, households and pharmaceutical industry, and by boosting waste water treatment at municipal waste water treatment plants.

Less cyanobacteria have been observed at national algae monitoring sites as compared to last week. Windy and cloudy weather has restrained the occurrence of cyanobacteria both in the Finnish sea areas and in lakes.

This week, in both Finnish sea areas and in inland waters, greater amounts of cyanobacteria have been observed as compared to last week. The warm weather period in June has promoted the growth of cyanobacteria, as is typical of heatwaves. With the continuing warm weather, the number of surface accumulations may still increase in the next few days.
