Low levels of cyanides are found in nature and in products we commonly eat and use. Cyanides can be produced by certain bacteria, fungi and algae. Cyanides are also found in cigarette smoke, in vehicle exhaust, and in foods such as spinach, bamboo shoots, almonds, lima beans, fruit pits and tapioca. There are several chemical forms of cyanide. Hydrogen cyanide is a pale blue or colorless liquid at room temperature and is a colorless gas at higher temperatures.
It has a bitter almond odor. Sodium cyanide and potassium cyanide are white powders which may have a bitter almond-like odor. Other chemicals called cyanogens can generate cyanides. Cyanogen chloride is a colorless liquefied gas that is heavier than air and has a pungent odor.
While some cyanide compounds have a characteristic odor, odor is not a good way to tell if cyanide is present. Some people are unable to smell cyanide. Other people can smell it at first, but then get used to the odor. Historically, hydrogen cyanide has been used as a chemical weapon. Cyanide and cyanide-containing compounds are used in pesticides and fumigants, plastics, electroplating, photodeveloping and mining. Dye and drug companies also use cyanides. Some industrial processes, such as iron and steel production, chemical industries and wastewater treatment can create cyanides.
During water chlorination, cyanogen chloride may be produced at low levels. People may be exposed to low levels of cyanides in their daily lives from foods, smoking and other sources. Eating or drinking cyanide-containing foods may cause health effects. Breathing cyanide gas, especially in a poorly ventilated space, has the greatest potential for harm. Lethal exposures to cyanides result only from accidents or intentional acts. Because of their quick-acting nature, cyanides may be used as agents of terrorism.
After exposure, cyanide quickly enters the bloodstream. The body handles small amounts of cyanide differently than large amounts.
In small doses, cyanide in the body can be changed into thiocyanate, which is less harmful and is excreted in urine. In the body, cyanide in small amounts can also combine with another chemical to form vitamin B 12 , which helps maintain healthy nerve and red blood cells. Large doses of cyanide prevent cells from using oxygen and eventually these cells die. The heart, respiratory system and central nervous system are most susceptible to cyanide poisoning.
But Rasputin just kept eating them. Instead of collapsing into unconsciousness within seconds, as would be expected from a massive dose of cyanide, Rasputin continued to sip the wine like a connoisseur. Having ingested their whole stock of cyanide, the group of assassins were somewhat at a loss as to what to do next. The bullet appeared to have entered the body near the heart — certain death, or so they thought. There was a ferocious struggle before the prince could free himself and run away up the stairs.
Rasputin followed. The whole account sounds fanciful from start to finish, but remarkable things do happen. Human beings have achieved incredible physical feats in spite of horrible injuries. During a duel in the sixteenth century one man received a stab wound directly to the heart but still managed to run yards to chase down his opponent before collapsing. Maybe Rasputin really was still alive after the first shot and capable of a fight. But what about the poison?
Surely no one could eat so much cyanide with so little effect? What is surprising is that the theories are scientifically credible. The first theory is that the poisoners were simply rubbish at their job. Born in a small railroad town in Susquehanna, Pa. Your e-mail won't be published. Skip to content.

The prognosis for poison ivy , oak , or sumac rash is generally good.
The rash and itching usually get better gradually and go away completely in two to three weeks. Treatment should be continued at least this long because the rash can come back if medicines are stopped too soon.
