汞污染也就是水银。我们用的温度计中的液体金属是汞。汞污染的问题总是伴随

Mercury pollution is mercury. The liquid metal in the thermometer we use is mercury. The problem of mercury pollution is always with us. Of course, there are many places that can be used. Therefore, the rational use of mercury can reduce the discharge of mercury and reduce the pollution of mercury. <br>1. The source of mercury <br>This is mainly due to mercury pollution caused by human activities, mainly produced by waste water and waste discharged from large-scale industries such as batteries and electronics. According to statistics, the total amount of mercury directly discharged into water by human activities in the world is about 16,000 tons, and the total amount of mercury to the atmosphere is about 11,000 tons. The mercury emitted in the soil is 100,000 tons, and the mercury in the atmosphere and the soil is 100,000 tons, and it returns to the water body with the circulation of water. Therefore, mercury pollution is mainly reflected in the pollution of water quality. <br>2. The main forms of mercury in water: <br>Hg2+ easily forms complexes in water, and the coordination number is generally 2 and 4; Hg22+ has a much smaller tendency to form complexes than Hg2+. In general natural waters, Hg2+ may form a fairly stable complex with CI-, which contains [C-]

Mercury pollution is also mercury. The liquid metal in the thermometer we use is mercury. The problem of mercury pollution is always with us. Of course, there are many places that can be used, so the rational use of mercury, reduce mercury emissions, reduce mercury pollution.<br>1, the source of mercury<br>This is mainly due to mercury pollution caused by human activities, mainly from waste water and waste from large-scale industries such as batteries and electronics. According to statistics, the total amount of mercury discharged directly into water by human activities in the world is about 16,000 tons, and the total amount of mercury discharged into the atmosphere is about 11,000 tons. With 100,000 tons of mercury emitted from soil and 100,000 tons of mercury in the atmosphere and soil, mercury pollution is mainly reflected in water quality pollution as water cycles back into the water body.<br>2.
