Toxic gold algae threatens the Oder: Measures to save the fish
Toxic gold algae threatens the Oder: Measures to save the fish
in Poland significant efforts are currently being made in order to curb the spread of the poisonous gold algae Primnesium Parvum. After the worrying incident in the side waters of the Oder, where the tons of dead fish were discovered, the authorities try to prevent fish deaths similar to in 2022
The Polish environmental minister Paulina Hennig-Kloska personally dealt with the situation and visited the Gleiwitzer channel at the weekend. The first measures to combat the algae blossom were taken with hydrogen peroxide, a chemical means that has already been used in the past to combat damage.
Environmental Authority express concerns
However, the campaign is viewed skeptically by environmental organizations such as Greenpeace. Katarzyna Bilewska, a spokeswoman for the organization, expressed that the use of hydrogen peroxide was nothing more than a "drop on the hot stone". She fears that without fundamental changes in industrial policy and the termination of the introductions of salt -containing wastewater into the waters, the problems cannot be solved sustainably.
The truth is that the poisonous gold algae is not just a local but also a far-reaching environmental problem. Their spread can extend over rivers and lakes and has direct consequences for water quality and biodiversity in the region.
Significant quantities of dead fish
Since the beginning of August alone, over 100 tons of dead fish have been recovered in the Dzierżno-Stausee. These alarming numbers show that the situation is serious and there is an urgent need for action. Environment Minister Różyk reported that the water is contaminated by industrial waters, which further worsens the living conditions for the fish.
Despite the challenge, the Polish government suggests proactive measures. It is indicated that the first test situation on the Kłodnica River has achieved promising results and that environmental protection measures are continuously checked. "We have stopped the inflow of the water with gold algae," says the minister optimistically.
As part of their research, the scientists also decrypt the genetic material of the gold algae, which could be important for future control strategies. Such scientific breakthroughs are necessary in order to understand and target the repeated natural disasters.
Gleiwitzer channel remains affected and continues to fight with high concentrations of the gold algae, which not only endangers the fish stocks, but also the entire water ecology. "We do not assume that there will be a mass die of fish like 2022," Różyk assures, but many experts agree that this is no reason for the all -clear.
The discussion about environmental policy in Poland continues, while the government is trying to take effective measures in the face of an ecological crisis. With the increasing pressure of environmentalists, it becomes clear that new solutions and possibly also investments in sustainable methods are necessary.
New handling of local water resources
It remains to be seen which long-term strategies the Polish authorities will develop in order to maintain the fight against the gold algae and its catastrophic consequences for the orcast. The topic remains highly up to date and is of central importance for the health of regional waters and the quality of life of the residents.
background of the problem with the gold algae
The toxic gold algae Primnesium Parvum has been a serious problem in the waters of Oder and their inflows for years. This algae blossom is primarily favored by increased nutrient pollution from agricultural fertilizers and industrial waste water. Especially in summer, at high temperatures and little water, the algae reach dangerous concentrations that endanger not only the ecosystem but also the fish population. In 2022 there was already a massive fish death that rang the alarm bells in both Poles and in Germany. Measures to reduce nutrient entries have so far been insufficiently implemented, which explains the recurring problems.
In 2021, a similar algae blossom led to an ecological disaster and an enormous loss of living beings. Historical data show that the ecosystem of Oder suffers from the influence of human activities. Pollution caused by industrial wastewater, in particular mines, contributes to salt and creates optimal conditions for the algae. These challenges require a comprehensive and cooperative strategy of the adjacent states to secure the long -term state of health of the waters and their residents.
Current measures and challenges
The Polish authorities have tackled various strategies to combat the gold algae. The use of hydrogen peroxide represents a short -term solution, which should show success, especially in the initial phase of algae management. While the minister speaks of success, environmental protection organizations like Greenpeace see the situation skeptical. Long -term solutions such as the desalination of industrial wasters and a strict regulation of the nutrient entry into the waters are essential.
The creeping but continuous pollution from salt -containing waste water is one of the main causes for the ongoing algae growth. Despite the experimental measures, the question remains open how effective these strategies are with regard to combating the causes and not just the symptoms. Some experts advocate that the parties have to pull together to renaturate the inflows and to reduce industrial introductions together.
relevant statistics and data on algae flower
Numerous scientific studies have shown a significant increase in algae flowers in recent years. Especially at temperatures above 20 degrees Celsius and excessive fertilization, there is an exponential growth of gold algae. According to the international commission to protect the or the number of algae flowers has doubled in the past five years.
A survey among residents and fishermen in the region showed that more than 70% of the respondents observe a deterioration in water quality. The quality of the fresh water is not only crucial for regional biodiversity, but also for human health, since many communities rely on the or as a source of drinking water. The excessive algae blossom has already led to fishing and swimming in certain areas to minimize health risks.
The challenges related to the gold algae underline the need for integrated water management and a sustainable handling of resources, not only in Poland, but also in the adjacent countries. This requires robust cooperation at European level to develop common standards and effective measures.
