Description

Large, blue or ultramarine, triclinic crystals or blue granules or light-blue powder; [HSDB]

Sources/Uses

Used as a fungicide and algaecide; [Rosenstock, p. 983] Also used as a mordant in textile dyeing; [www.ci.tucson.az.us/arthazards/medium.html] Used to kill roots invading septic tanks; [Goldfrank, p. 1257]

Comments

Granules or crystals can cause first degree burns on short exposure. [CHRIS] Can cause "vineyard sprayers lung," a form of hypersensitivity pneumonitis that was reported in agricultural workers in Portugal; [Rosenstock, p. 346, 983] "Studies on exposure to copper dust or fumes in industry as a possible cause of chronic lung disease are mostly negative." Fifteen cases of vineyard sprayers lung were reported in 1968-1973 and attributed to inhalation of copper sulfate in "Bordeaux mixture," but the role of copper has not been fully explained. [Nordberg, p. 778] Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1259-60] A severe skin, eye, and respiratory tract irritant; [ICSC] See "Copper."
