If the heat does not recede, the threat of algae blooms in the Baltic sea will continue, and their concentration may be the highest for the entire history of observations Institute of meteorology and hydrology of Sweden, according to Sputnik Estonia.

According to experts, now cyanobacteria, or blue-green algae, attacking almost the entire Central part of the Baltic sea.

Previously, the Department of health of Estonia recommended that the inhabitants of the country to refrain from swimming at some local beaches. However, a marine microbiologist at the Institute of marine systems Tallinn technical University Kai, Kunnis-Beres told Sputnik Estonia, today the wind direction has changed, therefore, most of the blue-green algae back out to sea.

According to her, to inform people on the beaches in the water is blue-green algae, have members of the coast guard. Also before going to sea, you can contact the health Department and get all necessary info from them, says, Kunnis-Beres.

The specialist noted that blue-green algae are the oldest living organisms on the planet. These microorganisms can multiply quickly, but they need favourable conditions: the nutrient-rich water and high temperature. If it becomes colder, and cyanobacteria disappear from coastal waters.

Some species of cyanobacteria produce toxins that adversely affect humans and animals, and so the microbiologist recommends that in the period of their active flowering to take special care.
«In the case of mass bloom of cyanobacteria can cause people skin redness, itching or rash. Reaction to the algae at everyone, it all depends on skin sensitivity and the degree of allergiesthe particular person,» he said Kunnis-Beres.

It is necessary to limit the stay of children and animals in areas where there is a large concentration of blue-green algae, as the toxins these bacteria can cause poisoning. After contact with the water in which the algae bloom, you need to wash and change.

The world health organization klassificeret cyanobacterial toxins for their effects on the human body. Hepatotoxins affect the liver, neurotoxins on the nervous system, cyanobacteria species Cylindroapermopsis raciborski – can produce toxic alkaloids (organic compounds) that cause people gastrointestinal symptoms or kidney disease.

Symptoms of poisoning blue-green algae are similar to flu symptoms: fever, muscle pain, headache, nausea, diarrhea, chills, fatigue and runny nose.
