Blue-green algae (cyanosis) are quickly taking over all Polish seaside resorts. Within only a few days red flags have been placed on beaches from Rewa to Stogi and Sobieszewo in Gdańsk. There are no-bathing signs in towns along the Hel peninsula as well.
The toxic blue-green algae have attacked almost all of bathing areas in and around the Tri-City.
The following beaches in the Tri-City area are closed:
- Gdańsk Jelitkowo
- Molo Gdańsk Brzeźno
- Dom Zdrojowy Gdańsk Brzeźno
- Gdańsk Stogi
- Gdańsk Sobieszewo
- both beaches in Sopot
- Gdynia Babie Doły
- Gdynia Śródmieście
- Gdynia Redłowo
- Gdynia Orłowo
Blue-green algae, unfortunately, also appeared on the Hel peninsula which, as experts argue, does not happen often. Bathing is prohibited on four beaches in Jastarnia, beaches in Jurata and Kuźnice and bathing areas No. 4, 6, 9 and 10 in Władysławowo, and 12 and 13 in Chłapowo. All the beaches on the bay side are also closed (Rewa and Mechelinki).
According to the Polish Board of Health (Sanepid) the situation is really serious, because there have not been so many algae for a very long time, and they are quite dangerous. The cyanosis is a bacteria that can cause abdominal cramps, vomiting, rashes, ulcers, and also intensify allergies. It blooms mainly in high temperature. Lack of waves and wind is also favourable. Board of Health warns that bathing in water infested by cyanobacteria can cause skin irritation and respiratory and digestive problems.
Experts take samples of water every few days and check its condition. The situation changes dynamically, and it is possible that soon more beaches on the Baltic coast might get closed.
