Category
Arsenic Compounds, Inorganic
Description
Yellowish-green solid; Variable composition; [Merck Index]
Sources/Uses
Used as a pigment, wood preservative, insecticide, fungicide, and rodenticide; Some uses are diminished in recent years because dimethyl arsine may be liberated by action of molds; [HSDB]
Comments
Toxic by ingestion: Can cause severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders, shock, and death; Other effects of arsenic poisoning are neuropathy, skin pigmentation, and injury to the liver, kidneys, and bone marrow; [ICSC] Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1259] See "Copper." See "Arsenic" and the linked occupational diseases.
Restricted
Not found in any pesticide products registered in the US; [NPIRS]
