Due to Thursday's bloom of cyanobacteria, health services have begun to close the open water bathing areas in the province. Pomerania. Bathing in water contaminated with cyanobacteria can cause unwanted reactions of the body: rashes, hives and pruritus to redness and conjunctivitis, and in case of ingestion, – gastrointestinal discomfort, diarrhea, vomiting, abdominal pain and even fever, chills, shortness of breath and dizziness.
Although not all cyanobacteria are dangerous to humans, it is generally difficult to say what kind of cyanobacteria we are treating. Some cyanobacteria can even cause damage to the liver, kidneys or thymus. Some of their varieties also have carcinogenic properties. It is important to carefully check if the water in which we enter is clean.
Anna Obuchowska, Deputy Director of the Health and Epidemiological Station of Gdańsk Voivodeship, explains that the situation can change at any time. Winds and currents cause the rapid displacement of clumps of cyanobacteria. Some closed swimming areas can be opened on the same day. In other places, however, a bathing ban may be declared at any time:
"
Rescuers in individual bathing areas observe water and, depending on their condition, decide whether to close or open.

What is cyanobacter and how do they affect human health?
Cyanobacteria or cyanobacteria, are self-sufficient organisms belonging to the kingdom of bacteria. They are counted among one of the oldest bodies on Earth. They appear in many places, however, more often than not, we realize their presence when they attack the swimming area with increased strength.
Swimming in water in which cyanobacteria bloom in increased numbers is harmful. Their excess makes that water has a characteristic green color, sometimes a "quilt" of organisms resembling algae. The flowering period of cyanobacteria falls during the summer season. We can meet them both in the sea and in the lake or the river.

The conditions for such blooms of zinnia are as follows:
- water temperature above 16-20 ° C (although known to proliferate cyanobacteria and at lower temperatures),
- availability of biogenic salts (especially phosphates) ),
- weak wind,
- small waves / water stagnation,
- ] no rain
Contact with cyanobacteria present in water (usually rotten, irritating odor) can lead to many conditions. They are caused by microcystins – toxic substances that promote:
- skin irritation in the form of rashes or blisters,
- eye and conjunctival irritation,
- abdominal pain, vomiting and nausea,
- irritation of the throat and mouth,
- muscular and joint pains,
- fever
- pain and dizziness,
- deterioration of well-being,
- cough,
- pneumonia and respiratory problems,
- gastrointestinal irritation,
- 19659009] gastrointestinal burn, [19659009] liver and kidney injury
It should be noted that:
- to avoid contact with cyanobacterial fur and water of changed color and unpleasant odor,
- not to drink domestic animals with cyanobacteria,
- n. do not use water with cyanobacteria for economic purposes (eg If you come into contact with cyanobacteria toxins, you must:
- Rinse the body thoroughly with cold water, remove bathing suit or clothes that have been in contact with contaminated water (clothes must be washed), contact your doctor or ask for help. of medical aid
We have more and more cyanobacteria in the Baltic for a year. Why?
WWF Polska ecologists explain that although the proliferation of cyanobacteria is a natural phenomenon, the scale of this phenomenon in the Baltic Sea is increasing every year . The increase in the concentration of organic components such as nitrogen and phosphorus compounds has a significant influence on this point.
"
The blooming cyanobacteria makes the water cloudy and begins to look like a stinking soup, which may have a brownish, reddish, greenish or yellowish color.
When this happens too often and the cyanobacteria are very numerous, this can lead to the withering away of life in the Baltic Sea .
Decomposition of dead cyanobacteria absorbs a lot of oxygen. Most often, fish and other organisms found in the sea are lost due to lack.
"Toxic species of cyanobacteria that can kill fish, birds and mammals are particularly dangerous (they also harm humans) .
Even after the blooming cyanobacteria, the toxins that they produce remain in the water for a while. So be careful when you go in the water.
