Very often houses build along highways. Researches showed that the premises located at distance no more than 500 m from the highway contain excess of tin. Everyone knows that dust from car tires is cancerogenic. And it is valid, tin creates conditions for emergence of malignant diseases. From there was an expression "cancer houses".
It is known that magnesium — our defender from cancer. But at poisoning with tin the content of calcium in an organism increases and the amount of magnesium decreases. Means if to increase a magnesium dose, it is possible to reduce toxicity of tin and to facilitate its allocation from an organism.
Bivalent magnesium reduces also hemolysis (erythrocytolysis) occurring under the influence of accumulation in a tin organism facilitates its allocation. It is often used also in medicine.
Symptoms of Poisoning with tin salts:
Tin does not belong to especially toxic metals, however excess of tin in an organism can be followed by unpleasant feelings (metal smack). At excess receipt tin collects in a liver, kidneys, a skeleton and muscles. Organic compounds of tin at receipt in digestive tract show the expressed cumulative effect with the subsequent development of aberation chromosomes in marrow cells.
In the beginning overall health worsens, locks, dizzinesses appear; constant headaches; visual disturbances; irritation of skin; станиоз (changes in lungs); loss of appetite; metal smack in a mouth; nausea, abdominal pains; increase in a liver; increase in level of transaminases in blood; hyperglycemia; decrease in contents in an organism of zinc and copper. etc. On the basis of these symptoms it is difficult to assume that as the reason of their emergence serves air pollution and waters tin. But later there is intestinal colic (it is called still "tin colic"), the blue-black inking of gums, pale gray skin color, an anemia appears, and, eventually, nerves and a brain are surprised.
Main manifestations of excess of tin: dizzinesses; constant headaches; visual disturbances; irritation of skin; станиоз (changes in lungs); loss of appetite; metal smack in a mouth; nausea, abdominal pains, ponosa; increase in a liver; increase in level of transaminases in blood; hyperglycemia; decrease in contents in an organism of zinc and copper.
It is considered that the content in blood of this metal in number of 35 mg on 100 ml can already cause functional changes of the central nervous system. Children and elderly people even a small amount of tin can have a fatal poisoning. Of course, individual portability of this metal is various, as well as reactions of an organism to its influence are various.
Reasons of Poisoning with tin salts:
Tin comes to a human body preferential with food. In milk and in fresh vegetables of concentration of tin are small and usually make 1 mkg/g and below. It is much higher than contents of tin in fats and fat fish (to 130 mkg/g). Tin can be present at canned food and a packaging foil.
During the day about 50 mg of tin come to an organism of the adult; 3-10% of this quantity are soaked up in digestive tract. In an organism generally tin is in a type of fat-soluble salts. In fabrics tin is present at concentration from 0,5 to 4,0 mkg/g. On a bone 0,8 mkg/g of tin, are the share of kidneys, heart and a small intestine - 0,1 mkg/g. In a brain of newborns tin is not found. Tin from an organism with bile and urine is emitted.
Believe that optimum intensity of intake of tin in an organism makes 2-10 mg/day. Deficit of tin can develop at insufficient receipt of this element (1 mg/day and less), and the threshold of toxicity is equal to 20 mg/day.
Treatment of Poisoning with tin salts:
Symptomatic treatment. There is no specific antidote.
