Reports that the Oder is heavily polluted and could lead to an ecological disaster appeared in the Polish media earlier this week. According to gazeta.pl, it is believed that the river was polluted in the Lower Silesian Voivodeship, in the vicinity of Olava, around July 26-17.
The water became cloudy, had an unpleasant smell, and thousands of dead fish floated to the surface.
Residents whose houses are near this river, as well as tourists, were constantly warned not only not to swim in the Oder, but also not to approach the water unnecessarily, as well as not to touch dead fish. It didn’t take long for reports to appear about other dead aquatic animals, a photo of a dead beaver was published on social networks.
The speculations that have been floating around for some time as to what could have contaminated the Oder are being dispelled by scientists.
Przemyslaw Daca, the director of “Polish Waters”, confirmed that the Oder was hit by a very serious ecological disaster. Thousands of fish died in Lower Silesia and Lubusz Voivodeships due to pollution.
German media reports that mercury has been found in river water samples. Rbb24.de writes that, according to the portal, the amount of this heavy metal was so high that it could not be determined, so it was decided to take new samples and repeat the tests.
However, it has not yet been confirmed whether mercury is the cause of fish spoilage.
“Mercury is toxic, especially harmful to children and pregnant women, damages the brain, kidneys, intestines,” warns Polish doctors.
According to them, if these data from German specialists are confirmed, this pollution of the Oder will pose a very serious threat to people. Mercury enters human bodies through the skin, respiratory tract, and digestive tract. Therefore, people are warned to be extremely careful.
Mercury is toxic, especially harmful to children and pregnant women.
Poles living near the Oder share their fears that the hot weather will not subside (in Poland, the temperature reaches +30 degrees and more), so the water in the river will start to evaporate, and dangerous substances will also evaporate at the same time. However, it is not known if anyone is testing groundwater and drinking water extraction sites.
According to Gazeta.pl, fishermen have already pulled out about 10 tons of dead fish from the Oder. Therefore, it is said that you can smell the river faster than you can see it – dead fish are there and give off a disgusting smell.
However, Grzegorz Witkowski, the Deputy Minister of Infrastructure, has already managed to cause indignation, who said that he would not be afraid to bathe in the river.
Polish Prime Minister Mateusz Morawiecki wrote in a tweet that he spoke with the leaders of the Lubusz Voivodeship about the situation in the Oder and obliged them to meet with the representatives of the municipalities. It is also indicated to check all water bodies both in this voivodeship and in others where the threat could also arise.
Who is responsible for the contamination has not yet been determined. However, it is feared that the pollution will soon reach the Baltic Sea.
The Oder, called Odra in Poland, is the second largest (after the Vistula) river in Poland, which flows through Poland (742 km, including the 187 km long border with Germany) and the Czech Republic (112 km). It flows into the Szczecin Lagoon, and then with three branches into the Baltic Sea.
