Sodium nitrate: terrible or nice

In most cases receiving sodium nitrate is based on synthesis of crystal substance from nitrogen of air or ammonia. Other technologies of receiving sodium nitrate represent various decomposition reactions or interactions of substances. For example, receiving sodium nitrate lixiviation from natural deposits hot water, crystallization, absorption of nitrogen oxides by solution of soda, decomposition of ammonium or calcic nitrate and the subsequent exchange with a carbonate, sulfate or sodium chloride is possible.

Sodium saltpeter is widely used in industrial production at production of corrosion-proof pipes, flew down, production of coolants and rocket fuel, and also is successfully applied in agriculture, medicine and the food industry. The medicines containing sodium nitrate are appointed as the bronchial spasmolytics, purgatives, means eliminating intestinal spasms and antidotes of cyanides.

By production of food stuffs, is more often than some sausages and cheeses, sodium saltpeter acts as the dye and preservative interfering distribution of the causative agent of a fatal disease – botulism; as nutritional supplement it is designated as E251. At the same time substance in high doses is extremely toxic for mammals, and when heating – heat treatment of products - has the proved cancerogenic activity.

For the person the highest daily dose of sodium nitrate makes 3,7 mg of substance on 1 kg of body weight, at the same time not the sodium, but nitric component is considered. So, at the body weight of 70 kg of 259 mg of E251 on the nitric _{NO3 group}there will correspond about 350 mg, that is to exceed admissible norm.

In a human body sodium nitrate solution as a result of metabolism is capable to cause air hunger of bodies and fabrics, and in high doses of a message to a serious poisoning, a fluid lungs, an acute heart failure and even death. At interaction with proteins in the course of digestion such solution forms carcinogenic substances.

Symptoms of poisoning with the Chilean saltpeter are abdominal pains, a posineniye of integuments, especially in the field of a nasolabial triangle and nails, a headache, spasms, the complicated breath, nausea, vomiting, diarrhea.

Sodium nitrate solution: the dose solves everything

Modern reality such is that the hope for life without dyes and preservatives can be considered illusion. Control of the consumed products and dosages of similar substances is vital today. So, the sodium nitrate solution containing 8-15 mg/l of dry matter is deadly to the person. Totally ammonium nitrates, potassium, calcium and sodium, should not exceed:

45 mg/l in drinking water;
130 mg/kg in soil;
60 mg/kg in water-melons, pears and apples;
400 mg/kg in vegetable marrows;
500 mg/kg in a late white cabbage;
250 mg/kg in potatoes;
80 mg/kg in onions;
250 mg/kg in late carrots;
1400mg/kg in beet.

When processing a harvest it is necessary to avoid steam inhalation of any organic nitrates, their hit on skin and in a digestive tract.
