Inhalation:The physical size of the alloy sticks makes inhalation or ingestion rather unlikely. The principal inhalation hazard would be the fumes or fine particles from the alloy when heated much above its melting point. These would be of indefinite composition, but it may be assumed that the highly toxic elements lead and cadmium would be present.
Lead can be absorbed through the respiratory system. Local irritation of bronchia and lungs can occur and, in cases of acute exposure, symptoms such as metallic taste, chest and abdominal pain, and increased lead blood levels may follow. See also Ingestion.
Cadmium absorption is most efficient via respiratory tract. Inhalation of dust may produce irritation, headache, metallic taste and/or cough. Severe exposures may produce shortness of breath, chest pain, and flu-like symptoms with weakness, fever, headache, chills, sweating, nausea and muscular pain. Can cause pulmonary edema, liver and kidney damage and death. Symptoms from inhalation may be delayed for as much as 24 hours.
