Turkey’s 5th largest lake Eznik has been temporarily banned from entering the lake due to the growth of cyanobacteria. Istanbul University Faculty of Aquaculture Professor. Dr. Following statements made on social media by Merik Cornell and Rehan Aksalan, a faculty member at Istanbul University’s Faculty of Aquatic Sciences, the provincial health department has put up warning signs to temporarily ban swimming in Eznik Lake.
In a statement on social media about the bacteria that make the lake green, Istanbul University Faculty of Aquatic Sciences Professor Dr. Dr. “High levels of cyanobacteria have been growing in Lake Eznik in the last few days. As a precaution, the use of the lake needs to be limited, as in many countries, especially for swimming,” said Merich Colonel. No entry into the lake after shouting.
“We think we’re doing something wrong.”
Rehan Akchalan, a faculty member at Istanbul University’s Faculty of Aquatic Sciences, said: This is especially true of areas where people go swimming in the lake. Since the growth of this process can be toxic, it would be appropriate to warn against entering the lake. On June 5, World Environment Day, Lake Eznik reminds us that we have done something wrong. “
“Despite the mark, still floating”
Following the warnings of experts, the Bursa Provincial Department of Public Health has put up a warning sign to temporarily ban swimming in Lake Eznik. “For the first time in our country, a public beach was closed for swimming due to the rapid growth of cybacteria,” said the colonel. More than 30 years of hard work have finally paid off. Although people are still swimming despite the signs, raising awareness will solve the problem. ”
I“This is due to excessive use of fertilizers and pharmaceuticals.”
Cyanobacteria have increased in the pollution caused by uncontrolled agriculture in the lake, said Evansel. Dr. “As Istanbul University’s Faculty of Aquatic Sciences, we have been conducting research on Iznik Lake since 1993. We see that it is one of the most polluted areas in Turkey. The agricultural area around the lake is very fertile. Sometimes the same area is 3 times a year,” Merich told DHA. It is used to grow a variety of vegetables, which means a lot of fertilizers and pesticides are used. Some of these are mixed with lakes. These pollutants with high nitrogen and phosphorus content cause excessive growth of cyanobacteria in the lake. They grow mainly in lakes, dams, and drinking water bodies. Our people call these algae algae, but they are actually algae. The cause has become clearer. Power will cause problems in the coming years. Therefore, constant monitoring of the growth and formation of algae in the lake is crucial. Arrangements need to be made around the lake. In particular, it is important that agricultural activities are strictly regulated and that water extraction, including groundwater, is planned in a more controlled manner that does not disturb the ecosystem. Farmers need to control the use of fertilizers and pesticides. The Ministry of Agriculture and Forests in particular has a huge responsibility here. Lake Iznik is the 5th largest lake in Turkey. It is a lake with a depth of 75-80 meters. Large lakes are quite difficult to pollute. We saw bird deaths and fish deaths there a few years ago. Lake health should be taken care of because cyanotoxins produced by cyanobacteria cause health problems.
“Organisms that trigger liver cancer”
Mentioning that cyanobacteria trigger liver cancer, Meriç Albay said: “Due to climate change and uncontrolled waste in almost every part of Turkey, the growth of cyanobacteria can be seen everywhere. It seems to be a problem in Istanbul’s drinking water dams and lakes. However, it is possible to treat cyanotoxins. They are already regularly analyzed. Cyanobacteria are organisms that cause liver cancer. Skin burns can cause health problems such as abdominal pain, diarrhea, etc. However, if the water is treated properly, there will be no problem. So far, I have not encountered such problems in Istanbul, especially between late May and mid-October. Until midnight, the water should be carefully monitored and the amount of cyanobacteria should be measured. According to the World Health Organization, immediate action should be taken if the amount of microcysteine in raw water exceeds 1 microgram.
“Due to climate change, there is a problem in the world”
Cornell, “Extended cyanobacteria is a biological problem that is closely followed in the world. Climate change is a big problem around the world. There have been a lot of deaths from Brazil in many countries. So there’s a lot of attention. The World Public Health Organization, both Set standards for both drinking water and swimming water অনেক In many countries around the world, standards have been set for drinking water and swimming water. It closes the area, “he said.
What are cyanobacteria?
Cyanobacteria or blue-green algae, whose overgrowth threatens water resources, are phytoplankton species caused by an increase in air temperature and nitrogen and phosphorus in the water.
