According to the lighting industry, due to the limitations of the manufacturing process, the current lighting products will always contain a little mercury. The high-pressure mercury lamp mainly utilizes the high pressure generated when mercury is discharged, thereby obtaining high visible light luminous efficiency. Both mercury and mercury compounds can enter the body through the skin, which is very slow and can cause irreversible damage to liver and kidney function, central nervous system and autonomic nerve function.
Mercury can evaporate at normal temperature. After the broken lamp tube is broken, mercury will enter the atmosphere as a vapor. Instantly, the concentration of mercury in the surrounding air can reach 10 mg to 20 mg/m3, and once inhaled 2.5 g of mercury vapor. People die.
