| Comments |
An eye and respiratory tract irritant; Can cause metal fume fever after inhalation and injury to the liver and kidneys after ingestion; [ICSC] Copper-induced metal fume fever is not as common as zinc-induced because of the higher temperature required to produce copper oxide. (Zn mp = 419.5; Cu mp = 1083 deg C.) Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1297-1302] See "Copper." |
