Strontium — the characteristic of properties with a photo, its biological role in a human body, treatment by preparations on the basis of a chemical element
Strontium — metal of alkaline earth character. It is a silver-white substance (see photo), very soft and plastic, easily cut even with a regular knife. It has a high activity, burns in the presence of air, enters into chemical interactions with water. In natural conditions in its pure form is not detected. Basically it is found in the composition of fossil minerals, usually in combination with calcium.
It was first found in Scotland at the end of the 18th century in a village called Stronsian, which gave the name to the found mineral, strontianite. But only 30 years after the discovery, the English scientist H. Devi was able to isolate it in its pure form.
Element compounds are used in the metallurgical industry, medicine, and food industry. It is very interesting for its property to emit red lights when burning that they adopted pyrotechnics in the early 20th century.
The action of the macro is often attributed to high toxicity and radioactivity. But such an opinion is quite erroneous, since the natural element practically does not possess these qualities and is even present in the tissues of biological organisms, fulfilling an important biological role and some functions as a satellite of calcium. Due to the properties of the substance, it is used for medical purposes.
The main accumulations of strontium in the human body accounts for bone tissue. This is due to the fact that the element is similar to calcium in chemical action, and that in turn is the main component of the «construction» of the skeleton. But the muscles contain only 1% of the total mass of the element in the body.
Also strontium is present in sediments of gall and urinary stones, again in the presence of calcium.
By the way, about the harmfulness of strontium — only radioactive isotopes have a destructive effect on health, which by their chemical properties practically do not differ from the natural element. Perhaps for this reason, this confusion arose.
The daily rate of the macro is about 1 mg. This amount is quite easily replenished with food and drinking water. In total, approximately 320 mg of strontium is distributed in the body.
But it should be borne in mind that our body is able to absorb only 10% of the incoming element, and we get up to 5 mg per day.
A macroelement deficiency can only theoretically cause some pathologies, but so far this has been shown only in animal experiments. So far, scientists have not revealed the negative impact of strontium deficiency on the human body.
At the moment, only some dependences of the assimilation of this macrocell have been revealed under the influence of other substances in the body. For example, some amino acids, vitamin D and lactose intake contribute to this process. A nasty effect of drugs have, on the basis of barium sulfate or sodium, as well as products with a high content of coarse edible fibers.
There is another unpleasant feature — when a calcium deficiency occurs, the body begins to accumulate radioactive strontium even from the air (often polluted by industrial enterprises).
What is the danger of strontium for humans and what is its harm?
Strontium, after all, can have a harmful radioactive effect. The element itself does little harm, and a critical dose has not yet been established. But its isotopes can cause disease and a variety of disorders. Like natural strontium, it accumulates in the skeleton itself, but its action causes damage to the bone marrow and the destruction of the bone structure itself. It can affect the brain and liver cells, and thus cause the occurrence of tumors and tumors.
But one of the worst consequences of an isotope is radiation sickness. In our country, the consequences of the Chernobyl disaster are still being felt and the accumulated reserves of radioactive strontium make themselves felt in the soil, water and the atmosphere itself. You can also get a large dose by working in enterprises using the element — there is the highest level of bone sarcoma and leukemia.
But natural strontium can cause unpleasant consequences. Due to a rather rare set of circumstances, such as an inadequate diet, lack of calcium, vitamin D and an imbalance in the body of elements, like selenium and molybdenum, specific diseases develop — strontium rickets and Urians disease. The latter received its name from the locality where local residents suffered from them in the 19th century. They became disabled due to the curvature of the skeleton structure, bones and joints. And for the most part those people who grew up in these places since childhood have suffered. Only in the 20th century did they find out that the waters of the local river contained an increased amount of the element. And in the period of growth, it is the osteo-articular system that is most affected.
Strontium oxide on the mucous membranes of the mouth or eyes, can cause burns and deep damage. And inhaling it with air can contribute to the development of pathological diseases in the lungs — fibrosis, bronchitis, and also heart failure.
As a treatment, usually used drugs based on calcium, magnesium, sodium sulfate or barium. It is also possible to use complexing agents that bind and remove radioactive toxins from cells.
Once in the soil, the toxic isotope of strontium can thus accumulate in the fibers of plants, and then in animals. Thus, the human body slowly but surely accumulates toxins by consuming poisoned products. Thermal treatment of products, which contributes to a rather significant reduction in the content of harmful toxin in them, can save the situation.
This radionuclide is very difficult to be removed from the body, because it can take him almost half a year to get rid of at least half of the accumulated stock.
Products containing strontium, in the bulk of this plant — wheat and other cereals, cabbage, dill, parsley, tomatoes, beets. In food of animal origin, this element is concentrated in cartilage and bone tissue.
Indications for treatment based on this element
Indications for the appointment of the macro, despite its possible toxicity is still there. And even a radioactive isotope is used for medical purposes. Its radiation in the allowed doses can have a therapeutic effect on erosion, tumors on the skin and mucous membranes. With deeper foci, this method is already used.
Also, its compounds serve as drugs for the treatment of epilepsy, nephritis and the correction of deformity in childhood by orthopedists. To some extent, can serve as an antihelminthic.
