Sample of arsenic trioxide in powder form. Medical use of arsenic trioxide refers to the use of arsenic trioxide (Latin: Arsenum trioxydatum, [1] also known as "arsenic") as an chemotherapeutic agent in the treatment of acute promyelocytic leukemia. Arsenic trioxide has orphan drug status [2] and is available as the pharmaceutical preparation ...
Arsenic biochemistry is the set of biochemical processes that can use arsenic or its compounds, such as arsenate. Arsenic is a moderately abundant element in Earth's crust , and although many arsenic compounds are often considered highly toxic to most life, a wide variety of organoarsenic compounds are produced biologically and various organic ...
A variety of applications exploit arsenic's toxicity, including the use of the oxide as a wood preservative. Copper arsenates, which are derived from arsenic trioxide, are used on a large scale as a wood preservative in the U.S. and Malaysia, but such materials are banned in many parts of the world. This practice remains controversial. [11]
Arsenic is used in bronzing. [108] As much as 2% of produced arsenic is used in lead alloys for lead shot and bullets. [109] Arsenic is added in small quantities to alpha-brass to make it dezincification-resistant. This grade of brass is used in plumbing fittings and other wet environments. [110] Arsenic is also used for taxonomic sample ...
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 ]
Arsenic sulfide (Xiong Huang) is a toxic mineral used in TCM to kill parasitic worms and treat sore throats, swellings, abscesses, itching, rashes, and malaria. [105] [106] Arsenic, while possibly essential for life in tiny amounts, is extremely toxic in the amounts used and arsenic poisoning may result from use of arsenic containing remedies ...
For example, the mold Scopulariopsis brevicaulis produces significant amounts of trimethylarsine if inorganic arsenic is present. [10] Biomethylation of arsenic compounds starts with the formation of methanearsonates. Thus, trivalent inorganic arsenic compounds are methylated to give methanearsonate. S-adenosylmethionine is the methyl donor.
Arsenicals are chemical compounds that contain arsenic. [1] [2] In a military context, the term arsenical refers to toxic arsenic compounds that are used as chemical warfare agents. This includes blister agents, blood agents and vomiting agents. [3] [4] Historically, they were used extensively as insecticides, especially lead arsenate.
