The primary use of arsenic is in alloys of lead ... The three most common arsenic allotropes are grey, ... the toxic form of arsenic to humans, to arsenate. Arsenate ...
Arsenic is a ubiquitous naturally occurring chemical element, and the 20th most common element on Earth. [13] Arsenic levels in the groundwater vary from around 0.5 parts per billion to 5000 parts per billion, depending on an area's geologic features, and possible presence on industrial waste.
Arsenic trioxide should not be mixed or administered in the same infusion with other medications. [92] In pharmaceutical compounding, arsenic trioxide was used in a 1:10 trituration with lactose (Trituratio Acidi arsenicosi 1/10). To prepare the trituration, one part arsenic trioxide is placed in a mortar, and while continuously grinding, nine ...
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 ...
Common sources include fertilisers; [17] aging water supply infrastructure; [18] and microplastics floating in the world's oceans. [19] [20] Arsenic is thought to be used in connection with coloring dyes. [21] Rat poison used in grain and mash stores may be another source of the arsenic. [22] The geographical extent of sources may be very large.
Arsenic trioxide powder.. Compounds of arsenic resemble in some respects those of phosphorus which occupies the same group (column) of the periodic table.The most common oxidation states for arsenic are: −3 in the arsenides, which are alloy-like intermetallic compounds, +3 in the arsenites, and +5 in the arsenates and most organoarsenic compounds.
Saccharides bound to arsenic, collectively known as arsenosugars, are found especially in seaweeds. Arsenic containing lipids are also known. [15] Although arsenic and its compounds are toxic for humans, one of the first synthetic antibiotics was Salvarsan, the use of which has long been discontinued.
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.
