The pigment was originally prepared by making a solution of sodium carbonate at a temperature of around 90 °C (194 °F), then slowly adding arsenious oxide, while constantly stirring until everything had dissolved. This produced a sodium arsenite solution.
Sodium arsenite can be inhaled or absorbed through the skin. Along with its known carcinogenic and teratogenic effects, contact with the substance can yield symptoms such as skin irritation, burns, itching, thickened skin, rash, loss of pigment, poor appetite, a metallic or garlic taste, stomach pain, nausea, vomiting, diarrhea, convulsions, decreased blood pressure, and headache.
Arsenite of lime and arsenate of lead were used widely as insecticides until the discovery of DDT in 1942. [ 78 ] [ 79 ] [ 80 ] In small doses, soluble arsenic compounds act as stimulants , and were once popular as medicine by people in the mid-18th to 19th centuries; [ 23 ] [ 81 ] [ 82 ] this use was especially prevalent for sport animals such ...
Emerald Green, also known as Paris Green, Scheele's Green, Schweinfurt green and Vienna Green, is a synthetic inorganic compound, made by a reaction of sodium arsenite with copper(II) acetate. While it makes a beautiful rich green, the color of the emerald stone, it is highly toxic , due to a main ingredient, arsenic . [ 18 ]

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 ...

Ortho-arsenite contrasts to the corresponding anions of the lighter members of group 15, phosphite which has the structure HPO 2− 3 and nitrite, NO − 2 which is bent. [1] A number of different arsenite anions are known: AsO 3− 3 ortho-arsenite, an ion of arsenous acid, with a pyramidal shape [1] (AsO − 2) n meta-arsenite, a polymeric ...
