An ordinary energy-saving lamp contains about 5 mg of mercury, which is only enough to be covered with a ballpoint pen tip, but it may cause 1800 tons of water to be contaminated after it penetrates into the ground. Because mercury has a low boiling point, it can evaporate at normal temperature. After the waste energy-saving lamps are broken, the concentration of mercury in the surrounding air can be exceeded by a hundred times. Once the mercury in the human body exceeds the standard, it will destroy the central nervous system of the human body, and the human body can kill by inhaling 25 mg of mercury vapor at a time.
China's energy-saving lamp promotion strategy has been in existence for a long time. In 2008 alone, 62 million energy-saving lamps were promoted nationwide. Until 2009, it was as high as 1.2 billion. The country promotes energy-saving lamps up to 200 million. China is still blank in the harmless treatment of energy-saving lamps. The broken energy-saving lamps are sent to the landfill for landfill with domestic garbage. In 2006, China's scrapped mercury-containing lighting appliances were equivalent to 1 billion standard fluorescent lamps of 40 watts, and the amount of mercury released into the atmosphere due to improper disposal reached 70-80 tons.
Because the old energy-saving lamps contain toxic and harmful elements such as mercury and lead, they are the second largest domestic waste “mercury pollution source” after the waste battery. The energy-saving lamp recycling system in China is very “naive”. If the disposal is improper, the pollution risk is not allowed. Neglect.
Some lead-type electronic fuel-saving lamps lead, mercury, lead in ballasts, polybrominated biphenyls and polybrominated diphenyl ethers in plastic parts exceed the standard; and some energy-saving lamps in the capillary, lamp holder, ballast all lead Exceeding the standard, mercury in the capillary exceeded the standard.
