According to the Xinhua News Agency, on January 15th, the fish raised by the masses in the Lalang Hydropower Station of the Longjiang River in the area of ​​Hechi City, Guangxi Province, suddenly suffered a lot of dead fish and caused local people to talk and reflect. The environmental protection department of the city after investigation found that the dead fish was caused by the excessive concentration of cadmium in the Longjiang River, and the Longjiang water body had suffered severe cadmium pollution.

On the 19th, Hechi City issued a circular saying that, coordinated by the local government, the upstream power station will increase the amount of discharge to effectively dilute the contaminated water. The local government is stepping up its monitoring and monitoring work, focusing on monitoring the purchase of raw materials by enterprises and the changes in the cadmium and arsenic content of waste water residues to find the source of pollution as soon as possible.

After the Longjiang cadmium exceedance event was disclosed, it caused a significant impact among people along the Yangtze River and downstream areas. On the evening of the 25th to the 25th, a number of supermarkets in the downstream of Liuzhou, Guangxi Province, rushed to buy bottled water.

Encyclopedia: Cadmium Cadmium is a non-essential element in the human body and is often present in the compound state in nature. Under normal environmental conditions, cadmium will not affect human health. However, with the development of mining, refining, and electroplating industries, a large amount of cadmium-containing wastewater is discharged into rivers and causes cadmium contamination. Cadmium can be enriched in organisms and enter the body through the food chain. After being absorbed by the body, cadmium accumulates in organs such as the liver and kidneys, affecting the normal function of the enzyme system, impeding the growth and metabolism of bones, and causing symptoms such as osteoporosis, atrophy, and deformation.
