The fluorescent lamp is broken. Is the substance in the lamp poisonous?

The substance in the lamp tube is poisonous.

Traditional fluorescent lamps contain a lot of mercury vapor, which will evaporate into the atmosphere if it breaks down. Different kinds of atoms will release photons with different frequencies, which is the most basic working mechanism of almost all light sources.

The central element of fluorescent lamp is a sealed glass tube, which contains a small amount of mercury and inert gas, usually argon, to protect mercury vapor from chemical reaction. The inner wall of the lamp tube is coated with fluorescent substances.

The harm of the inflated information harmful waste cannot be underestimated. As far as waste lamps are concerned, Nanjing Daily introduced that most of the energy-saving lamps manufactured by current technology contain chemical element mercury, and an ordinary energy-saving lamp contains about 0.5 mg of mercury. If 1 mg of mercury seeps into the ground, it will cause 360 tons of water pollution.

Mercury also enters the atmosphere in the form of steam. Once the mercury content in the air exceeds the standard, it will do harm to human body, and long-term exposure to excessive mercury will lead to poisoning.

In addition, according to People's Daily, as far as expired drugs are concerned, most of them are easy to decompose and evaporate after expiration, emitting toxic gases, causing indoor environmental pollution, and even causing harm to human respiratory tract in serious cases.

If expired drugs are treated as domestic garbage, it will pollute the air, soil and water environment. We often say that excessive antibiotics in water and the emergence of more drug-resistant bacteria are also related to improper handling of expired drugs. ?
