Aug 14, 2024 · Following ingestion, cyanide is found in the stomach, with lesser amounts found in the spleen, blood, liver, brain, and kidney; it is found in the lung, blood, brain and kidneys following inhalation .
Urooj Khan (1966–2012), won the lottery and was found dead a few days later. [79] A blood diagnostic reported a lethal level of cyanide in his blood, but the body did not display any classic symptoms of cyanide poisoning, and no link to cyanide could be found in Urooj's social circle.

Symptoms of cyanide exposure typically appear within a few seconds to several minutes after exposure, and may include weakness, nausea,
headache, and difficulty breathing.
Cyanide is one of the most famous poisons — from spy novels to murder mysteries, it’s developed a reputation for causing an almost immediate death.
But in real life, cyanide is a little more complicated. Cyanide can refer to any chemical that contains a carbon-nitrogen (CN) bond, and it can be found in some surprising places.
For example, it’s found in many safe-to-eat plant foods, including almonds, lima beans, soy, and spinach.
You can also find cyanide in certain nitrile compounds used in medications like citalopram (Celexa) and cimetidine (Tagamet). Nitriles aren’t as toxic because they don’t easily release the carbon-nitrogen ion, which is what acts as a poison in the body.
Symptoms of toxic cyanide exposure may appear within a few seconds to several minutes after exposure.
You may experience:
•overall weakness
•nausea
•confusion
•headache
Cyanide poisoning is rare. When it does occur, it’s typically the result of smoke inhalation or accidental poisoning when working with or around cyanide.
You may be at risk for accidental exposure if you work in certain fields. Many inorganic cyanide salts are used in the following industries:
•metallurgy
•plastic manufacturing
•fumigation
•photography
If you’re experiencing symptoms of acute cyanide poisoning, seek immediate emergency medical attention.
If you’re experiencing symptoms of chronic cyanide poisoning, see your doctor right away. After discussing your symptoms, your doctor will perform a physical exam.
They’ll also conduct blood tests to assess your:
•Methemoglobin level. Methemoglobin is measured when there is concern for smoke inhalation injury.
•Blood carbon monoxide concentration (carboxyhemoglobin level). Your blood carbon monoxide concentration can indicate how much smoke inhalation has occurred.
•Plasma or blood lactate level. Cyanide blood concentrations usually aren’t available in time to help diagnose and treat acute cyanide poisoning, but they can offer later confirmation of poisoning.
The first step to treating a suspected case of cyanide poisoning is to identify the source of exposure. This will help your doctor or other healthcare provider determine the appropriate decontamination method.
In the case of a fire or other emergency incident, rescue personnel will use protective gear like face masks, eye shields, and double gloves to enter the area and take you to a safe location.
If you have ingested cyanide, you may be given activated charcoal to help absorb the toxin and safely clear it from your body.
Cyanide exposure can affect oxygen intake, so your doctor may administer 100 percent oxygen via a mask or endotracheal tube.
In severe cases, your doctor may administer one of two antidotes:
•cyanide antidote kit
If left untreated, acute or chronic cyanide poisoning may cause:
•seizure
•cardiac arrest
•coma
In some cases, cyanide poisoning may result in death.
If you suspect you or a loved one is experiencing symptoms of severe cyanide poisoning, seek immediate emergency medical attention.
Your outlook will depend on the type of cyanide present, the dose, and how long you were exposed.
If you’ve experienced low-level acute or chronic exposure, the outlook is usually good. Early diagnosis and treatment are key to reducing your risk of complications.
Moderate levels of acute or chronic exposure may also be resolved with quick diagnosis and treatment.
In severe cases, symptoms are often sudden and life-threatening. Immediate emergency medical attention is necessary.
There are ways to reduce your risk of cyanide exposure. You can:
•Take proper precautions against a home fire. Install and maintain smoke detectors. Avoid using space heaters and halogen lamps, and avoid smoking in bed.
•Childproof your home. If you have young children, childproofing your home is essential — especially if you’re at risk of occupational exposure. Keep containers holding toxic chemicals secured and the cabinets they’re kept in locked.
•Follow work safety regulations. If you work with cyanide, use removable absorbent paper to line work surfaces. Keep quantities and container sizes in the work area as small as possible. You should also make sure that you leave all chemicals in the lab or factory. Don’t bring home potentially contaminated clothing or work gear.

Dec 11, 2018 · Additionally, due to filtration by the kidneys, urine cyanide levels are much lower than the levels found in the blood . Identifying cyanide exposure in these matrices would require high sensitivity to allow clinicians to identify individuals exposed to levels of cyanide that are likely to suffer from adverse health effects.

Removal of cyanide from cassava in Nigeria.. Cyanides are produced by certain bacteria, fungi, and algae.It is an antifeedant in a number of plants. Cyanides are found in substantial amounts in certain seeds and fruit stones, e.g., those of bitter almonds, apricots, apples, and peaches. [5]
Cyanide is a potentially lethal toxic agent that can be found in liquid and gaseous form. First discovered in 1786 by Scheele, who extracted it from the dye Prussian blue – and promptly died from exposure to the vapours. Average lethal dose of prussic acid (hydrogen cyanide, HCN) taken by mouth between 60 and 90 mg (adult)

Jan 30, 2024 · About 35% of all fire victims have toxic levels of cyanide in their blood. However, deaths from cyanide poisoning are rare. Out of 3,165 human exposures during 1993–2002, only 2.5% were fatal.
