Mercury pollution of energy-saving lamps means that the energy-saving lamps are mainly composed of filaments, mercury and phosphors, and the mercury has a low boiling point and can be evaporated at normal temperature. After the discarded energy-saving lamps are broken, they can instantaneously be in the surrounding air. Mercury concentrations exceeded the standard by a hundredfold. An ordinary energy-saving lamp has an average mercury content of about 0.5 mg, which is only enough to be covered with a ballpoint pen tip. However, if it is improperly disposed, it will penetrate into the ground. According to the theory, 1 mg of mercury can contaminate 360 ​​tons of water. 0.5 mg of mercury may be used. Contaminated about 180 tons of water and surrounding soil. This causes environmental pollution and other problems, which is called "energy saving lamp mercury pollution."
