Copper powder. Health hazard: heavy inhalation of copper smoke may cause metal smoke fever. The patient has chills, elevated body temperature, and respiratory irritation. Workers exposed to copper dust for a long time often have contact dermatitis and irritation of the nose and eyes, resulting in sore throat, cough, nasal congestion, rhinitis, and even nasal septum perforation. Long – term inhalation may cause pulmonary fibrosis.

Copper can only be heated into CuO in an alcohol lamp, which is difficult to be oxidized in dry air, but easy to be oxidized in moist air to form basic copper carbonate (2Cu+O2+H2O+CO2==Cu2(OH)2CO3). Compared with copper sheet, copper powder is more easily oxidized because its surface is in contact with air.
Copper can be burned in chlorine gas, producing brown-yellow smoke and copper chloride (Cu+Cl2= ignition =CuCl2).
Forbidden compounds: strong acid, strong oxidant, halogen.
Conditions to avoid contact:
Acute toxicity: LD50: no data available
LC50: no data
Subacute and chronic toxicity:
Biological enrichment or accumulation:
Other harmful effects: threshold concentration of smell in water: concentration in water is 3-5mg/L, making water taste bad
