Affected by the high temperature, the main river in southeastern Korea, the Luodong River, has multiplied in large quantities, directly endangering the fisheries and water safety of the people in the basin.
At a pier in Gimhae, South Gyeongsang Province, South Korea, next to the reporter is The Rodong River, the longest river in South Korea, which flows through the southeast. The entire surface of the water was green, and the air was filled with a foul smell of mold.
You can see that the water quality is very turbid, and the local people use the "green tea latte" to describe it. From May to July this year, the precipitation in the Luodong River basin is less than 60% of that of previous years, and the continuous high temperature and sun have led to an increase in water temperature, coupled with the reservoirs and dikes in the upper and lower reaches of the Luodong River, the water flow in the middle of the river has slowed down, and the rapid reproduction of algae has covered the entire water surface.
In late June this year, the number of cyanobacterial cells per milliliter in some parts of the Luodong River exceeded 10,000, and many places began to issue algae warning alerts. In July, the number of cyanobacterial cells in these basins exceeded 100,000 four times, the highest value since South Korea formulated the relevant test method in 2016.
Fishermen told reporters that they could not fish at all, their income was almost zero, and the local people also began to buy aquatic products from other places.
The Nakdong River is home to more than 10 million people in southeastern South Korea, including Busan, South Korea's second-largest city. Because toxic substances that can induce liver disease have been detected in the water of the lower reaches of the Luodong River, people near the basin are extremely uneasy. At present, Busan City is promoting the program of water extraction in deep water areas with low algae concentrations and strengthening water quality monitoring, while the Ministry of Environment of South Korea has also asked all localities to shorten the replacement cycle of activated carbon in water purification plants and increase the treatment of highly purified water facilities.
Also plagued by algae is the South Korean island of Jeju. In the eastern waters of Jeju Island, due to the high water temperature, the recent seaweed flood, a large number of green seaweed covered the entire beach, resulting in tourists can not play, the local cleaned seaweed every day reached 400 tons. At present, all parts of South Korea are experiencing a new round of high temperature roasting, and many places have issued hot alarms. (CCTV Finance)
