Arsenic is a chemical element with the symbol As and the atomic number 33. It is a metalloid and one of the pnictogens, and therefore shares many properties with its group 15 neighbors phosphorus and antimony. Arsenic is a notoriously toxic heavy metal.
Frequency. >200 million [3] Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. [1]
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (20% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
Chemical agents. A blood agent is a toxic chemical agent that affects the body by being absorbed into the blood. [1] Blood agents are fast-acting, potentially lethal poisons that typically manifest at room temperature as volatile colorless gases with a faint odor. [1] They are either cyanide - or arsenic -based.
Arsenic is a neurotoxin commonly found concentrated in areas exposed to agricultural runoff, mining, and smelting sites (Martinez-Finley 2011). One of the effects of arsenic ingestion during the development of the nervous system is the inhibition of neurite growth [92] which can occur both in PNS and the CNS. [93]
Toxic and carcinogenic. Disintegrates on long exposure to light to a powder composed of pararealgar or arsenolite and orpiment. Realgar (/ riˈælɡɑːr, - ɡər / ree-AL-gar, -gər), also known as ″ arsenic blende ″, ″ ruby sulphur ″ or ″ ruby of arsenic ″, is an arsenic sulfide mineral with the chemical formula α - As4S4.
How to tell what your home actually smells like. Nose blindness is hard to prevent since, as Rowan explains, it’s a natural adaptation of the brain. However, there are things you can do to get a ...
Orpiment, also known as ″ yellow arsenic blende ″ is a deep-colored, orange-yellow arsenic sulfide mineral with formula As. 2S. 3. It is found in volcanic fumaroles, low-temperature hydrothermal veins, and hot springs and may be formed through sublimation. Orpiment takes its name from the Latin auripigmentum (aurum, "gold" + pigmentum ...
