Is arsine heavier than air?

Breathing in the gas (inhalation) is the most likely route of exposure after arsine is released into the air. Arsine vapor is heavier than air; so it would be more likely to settle in low-lying areas.

What is the formula of arsine gas?

AsH3
Arsine/Formula

What is the normal boiling point of arsine?

-62.5 °C
Arsine/Boiling point

What is arsine made of?

Arsine, colourless, extremely poisonous gas composed of arsenic with hydrogen (see arsenic).

What is the poison that smells like almonds?

Cyanide
Cyanide can be a colorless gas, such as hydrogen cyanide (HCN) or cyanogen chloride (CNCl), or a crystal form such as sodium cyanide (NaCN) or potassium cyanide (KCN). Cyanide sometimes is described as having a “bitter almond” smell, but it does not always give off an odor, and not everyone can detect this odor.

Why can I smell garlic in my house?

Phantosmia, as the name suggests, is the term for olfactory hallucinations, or phantom smells, that appear in the absence of any odour. These can manifest as ‘normal’ smells – for example, being able to smell garlic when there is no garlic present – but they can also be unpleasant.

What color is arsenic?

Arsenic is a naturally occurring element. In the pure form, it is a silver-gray, semi-metallic substance that tarnishes in air. However, arsenic is found in nature in various inorganic and organic compounds. Inorganic and organic arsenic compounds are white in color, and have no smell or special taste.

What is the chemical name of BiH3?

Bismuthine bismuthane
Bismuthine

Why is phosphine gas toxic?

Exposure results in pulmonary edema (the lungs fill with fluid). Phosphine gas is heavier than air so stays nearer the floor. Phosphine appears to be mainly a redox toxin, causing cell damage by inducing oxidative stress and mitochondrial dysfunction.

Is ph3 toxic?

Phosphine (IUPAC name: phosphane) is a colourless, flammable, very toxic gas compound with the chemical formula PH3, classed as a pnictogen hydride. Phosphine is a highly toxic respiratory poison, and is immediately dangerous to life or health at 50 ppm.

What happens if I eat a bitter almond?

When taken by mouth: Do not take bitter almond by mouth. Bitter almond is LIKELY UNSAFE. It contains a poisonous chemical called hydrogen cyanide (HCN) that can cause serious side effects, such as slowing of the nervous system, breathing problems, and death.

What are the properties of the gas arsine?

General properties At its standard state, arsine is a colorless, denser-than-air gas that is slightly soluble in water (20% at 20 °C) and in many organic solvents as well. Whereas arsine itself is odorless, owing to its oxidation by air it is possible to smell a slight garlic or fish-like scent when the compound is present above 0.5 ppm.

How is arsine ( SA ) released into the air?

Indoor Air: Arsine (SA) can be released into indoor air as a gas. Outdoor Air: Arsine (SA) can be released into outdoor air as a gas. Agricultural: Because arsine (SA) is not released into the air as fine particles (aerosol), it is highly unlikely to contaminate agricultural products.

Is it possible to ingest arsine ( SA ) gas?

Ingestion is unlikely because arsine (SA) is a gas at room temperature. Metal arsenides are solids that can be ingested; they can react with stomach acids to release arsine (SA) gas. Information is limited about absorption of arsine (SA) through, or arsine’s (SA) toxic effects on, the skin or eyes.

What is the odor threshold for arsine ( SA )?

The established PEL is 10 times lower than the concentration at which people begin to smell arsine (SA) (odor threshold of 0.5 ppm and above). Indoor Air: Arsine (SA) can be released into indoor air as a gas.
