The nature has presented to mankind surprising metal which we never saw firm. Silver water, or is more familiar - mercury. Medieval alchemists considered this metal magic and brought to the level of first-born elements. Today it is irreplaceable material in science and the electronic equipment. Many elements applied in everyday life as luminescence energy saving lamps, thermometers, radio components, monitors of computers, etc., contain mercury. Vapors of mercury are dangerous to the person.
Mercury as integral part of organism
As metal, mercury in the nature does not exist. IT is received from cinnabar, mineral, brightly scarlet saturated color of crystal. It is not dangerous to people. Mercury is present at any living organism. Besides finding of mercury in fabric or human organ, and it is about 13 mg, it bigger degree accumulates in kidneys, liver and the central nervous system. It is connected with feature of compound of mercury with proteinaceous molecules which with blood pass through these bodies.
The amount of mercury in organism, depends on conditions of activity, food and place of residence to which the person has got used. Scanty amount of mercury to a greater or lesser extent are present at seafood, vegetables, meat of animals.
But to live, having at all refused mercury - it is impossible. It has unique properties and replacements it should not be found so far. Mercury, it and the excellent catalyst in inorganic synthesis, necessary substance at production of medications. The science does not do without it when studying superconductivity, various atmospheric phenomena and in many other about what it is more in details provided in other sources of information. We will return to our everyday life where along with useful properties of mercury, it can constitute also danger.
Mercury and human health
Mercury is not removed from organism, and sovremeny collects. Thus, there is chronic poisoning. Even the short-term contact can lead to poisoning. At poisonings with high doses, the metal smack in mouth is felt, and then nausea, vomiting develops. Symptoms of poisoning are: fatigue, insomnia, lachrymation, irritations of skin, diarrhea, lack of appetite, cold, arise lapses of memory. In more hard cases of poisoning, there is violation of activity of brain, the immune system, lungs and kidneys. Muscular tremor, sharp loss of weight. At children the backwardness in intellectual development is observed. It is necessary to handle mercury extremely carefully. The shivering, silvery droplet seen somewhere in your dwelling, is dangerous not in itself, but that toxic fumes which of it evaporate. The safe standard of the contents of mercury in air is 0.016 mg on one CBM. But only 1 gram of mercury is capable to poison more than 3 million cubic meters of air but only in one medical thermometer, it there are about 3 grams. Vapors of mercury absorb various surfaces of rooms: fabrics, linoleum, parquet, plaster, etc. At change of conditions indoors (temperature, mechanical influence), mercury comes to room volume again. And so can occur infinitely long until demercurization is applied.
How to check presence of mercury in the apartment
Demercurization - the main measure for cleaning of mercury pollutions. If you have accidentally broken the thermometer and have collected all rolled-out balls, the room can be all the same infected. It is possible to understand it only by means of the special device - gas analyzer. Then chemical treatment is carried out. The purpose of chemical treatment is to oxidize dangerous evaporations. Experts flood all room with chemical, the containing iodine. As a result couples will turn into oxide or chloride of mercury and further it is not simple operation. The service of chemical demercurization is engaged in it. Otherwise not to remove mercury.
