Boric acid is actually a poison! Although poisons and this weak, it is very insidious properties! C


Congratulations, young supporters of chemistry on the page group "Himikus - Tsikavikus." Our group is designed for curious explorers of the world, those who do not consider boring chemistry who are interested in the unusual properties of all known and unknown substances!
Boric acid H 3 BO 3 can be seen in almost every medicine cabinet in pure form and in stock ointment, solution spytovoho - "The Bourne alcohol." In Handbook of medicines that produce millions of copies, you can read that "boric acid is used as an antiseptic in the form of aqueous solutions (2-4%) to rinse the mouth and eye wash, in the form of ointments (5-10%) prescribed for skin diseases. " For centuries, boric acid caring mother and grandmother used even eye wash newborn babies, not knowing bahan kitchen set that filtered child!
Boric acid is actually a poison! Although poisons and this weak, it is very insidious properties! Compounds of boron are not for certain bahan kitchen set microorganisms, like antibiotics, and all at once, because bahan kitchen set boron is the so-called cellular poison. A cunning of it is that the poison has no antidote and very slowly eliminated from the body. Boron affects the gastrointestinal tract, skin, kidneys, central nervous system. No wonder the use of boric acid inside was prohibited everywhere in the late XIX century. Until boric acid is used very widely. It is injected into the various creams and ointments used for cleaning teeth, when washing clothes and even food preservation. So, smoked beef that was delivered in the XIX century from America bahan kitchen set to Europe, bahan kitchen set containing up to 3.8% boron compounds! In Sweden, boric acid called "aseptin" used for preserving milk, meat, beer. Russian fishing industry used it for salting fish eggs, adding to 10 g per kilogram of product. bahan kitchen set In 1902, the Health Department issued a special circular banning the use of boric acid in the food industry as a preservative. Similar bans have emerged in many countries. But even if boric acid is swallowed, it can enter the body with ointments, eye and ear drops, lotions. It is easily absorbed through the mucous membranes. And since boron is excreted from the body very slowly, bahan kitchen set with repeated applications of boron, boric acid builds up and can reach dangerous levels. Especially fast it occurs in newborns and infants. In 1987, the Ministry of Health then the former USSR banned the use of boric acid for children and lactating mothers. bahan kitchen set Antimicrobial action of very weak and low price can not compensate for the damage to health.
We decided to investigate whether used boric acid in Ukraine, whether people know about the insidious properties of these "drugs". As soon as we sold the pharmacy and boric acid in pure form, and its alcoholic solution - "boric alcohol." Although instructions for preparations indicate that its use is contraindicated in pregnancy and children up to 1 year, there is a danger that the work "memory ever", and it will handle the kids eyes hazardous substances.
We investigated the antiseptic properties of boric acid in our experiment with preservatives fruit juices (Food Additives, Sodium Benzoate bahan kitchen set wins). bahan kitchen set Our experiment showed that boric acid shows very weak antibacterial activity. The appearance of mold on the juices she dragged a day. Boric acid does not prevent the appearance of mold (left) and sodium benzoate - a preservative efetyvnyy

The temperature in the trunk of lightning reaches 20 000 C, and the nitrogen reacts with oxygen, bahan kitchen set leading to the formation of about 2 million tons of nitric acid daily (or 700 million tons per year) World production bahan kitchen set of nitric acid is about 30 million tons per year
