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.
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.
Green pigments are the materials used to create the green colors seen in painting and the other arts. Most come from minerals, particularly those containing compounds of copper . Green pigments reflect the green portions of the spectrum of visible light, and absorb the others.

In ancient times, through the Industrial Revolution, various inorganic pigments like Egyptian Blue were synthesized, many with toxic chemicals like arsenic and antimony. These toxic pigments were used for cosmetics and painting. In ancient Egypt, blue was considered the color of the divine. As a result, the early synthetic compound Egyptian ...
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% 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]
Transition metal arsenate compounds are often brightly coloured and have been used to make pigments. Copper arsenate was a minor compound used in the Egyptian blue pigment used by the ancient Egyptians and Romans. [10] Cobalt violet pigment was made from cobalt arsenate before its toxicity led to its replacement by cobalt phosphate. [11] [12] [13]
