Mercury is the only metal in liquid form, can flow, small beads can be separated, but also together, look very cute, many children like, I also played as a child, but do not play as a toy! Will be poisoned! Here to tell you a story. There is a child, with a mineral water bottle from home filled with half a bottle of mercury to school, because the mercury is fun, the child will be the mercury as a “gift” to the class of good classmates, the results of the class in addition to a few poor relations with his classmates did not get the mercury, each of the other children’s stationery box he gave “The result was that every child in the class, except for a few students who were not on good terms with him, did not get mercury. Everyone had an extra toy that was fun to play with – mercury, bright and shiny, rolling around, really fun. As a result, 3 days later, many children had symptoms of poisoning such as pain in the limbs, mouth ulcers, neurasthenia, and even limb tremors in serious cases. After hospital examination, many children in the class were diagnosed with mercury poisoning, and all of those teachers and students who were not poisoned were examined all exceeded the mercury limit! And those few classmates who were not on good terms with him, the children who were initially sad because they were not assigned mercury, turned out to be the least poisoned. It turns out that fun mercury turns into mercury vapor, which is inhaled into the lungs with breathing and absorbed through the alveoli, damaging lung tissue and leading to chemical pneumonia, and mercury entering the bloodstream can damage the nervous system and even multiple organs throughout the body, leading to severe mercury poisoning! Mercury vapor can not only lead to poisoning of children playing with mercury, but also contaminate classrooms, pollute the home environment, and lead to poisoning of others! Also mercury vapor can be adsorbed on clothes, furniture and walls, leading to long-term pollution of the environment, which is difficult to be completely removed! Mercury, in the form of vapor, can easily be inhaled by the human body through the alveoli and absorbed by the body, resulting in serious toxicity; it is definitely not absorbed as rarely as it is swallowed by mistake into the digestive tract! Therefore, the “fun” mercury is never to play as a toy!
