Phosphor hazards:

Photoluminescent Tumbled GravelsSeveral hazards: As phosphors do neon tubes filled process, contain higher amounts of Hg, and therefore the main source of the harm is its dissemination of Hg vapor, authoritative information: mercury vapor 0.04 to 3 mg, it will chronic poisoning people in the February-March; up to 1.2 to 8.5 milligram quantities, can induce acute mercury poisoning, should the amount of 20 mg, will directly lead to death. Once mercury enters the human body, can be quickly dispersed and accumulated to the kidney, chest and other tissues and organs, chronic mercury poisoning can lead to mental disorders, autonomic disorders. Acute symptoms and headache,luminescent sheet fatigue, fever,
sore gums swelling, erosion bleeding, loose teeth and other parts of the skin red spots, pimples, a few kidney damage, individual kidney pain, chest pain, dyspnea, cyanosis acute interstitial pneumonia. Should custody and improper disposal of mercury, but also cause great harm to the environment, which in various forms into the environment, direct contamination of soil, air and water, and then enter the body through the food chain, endangering people's health living, and therefore must not be fluorescent, neon tubes discarded debris everywhere. If the indoor fluorescent tubes cracked, after available iodine of 1 g / cubic meter plus alcohol fumigation or directly with 1 g / cubic meter iodine dispersed on the ground set of 8 to 12 hours, so volatile or sublimation of iodine and mercury in the air to generate hard volatile mercuric iodide, for reducing the concentration of mercury vapor, but also with 5% to 10% of the ferric chloride or 10% bleach rinse contaminated ground
