Gesundheitsgefahren	Inhalation of fumes can produce coughing, chest constriction, headache, nausea, vomiting, pneumonitis. Chronic poisoning is characterized by emphysema and kidney injury. Ingestion causes gastrointestinal disturbance and severe toxic symptomsboth kidney and liver injuries may occur. Contact with eyes causes irritation. (USCG, 1999)
Gefahrenübersicht	See Cadmium and the linked diseases.The major hazards encountered in the use and handling of cadmium nitrate stem from its toxicologic properties. Toxic primarily by ingestion and inhalation, exposure to this odorless, colorless-to-white, crystalline substance may occur from its use in making other cadmium salts, in photographic emulsions, in coloring glass and procelain, and in the manufacture of nickel-cadmium batteries and turf fungicides. Effects from exposure may include headache, nausea, shortness of breath, chest pain, kidney damage, liver damage, emphysema, and intense pulmonary edema (possibly resulting in death). Processes and operations which may release cadmium fumes or dust should be enclosed and fitted with exhaust ventilation. In activities where overexposure is possible, workers should wear a high efficiency particulate filter respirator or self-contained breathing apparatus. Protective clothing also should be worn, including eye, face, and hand protection. All such clothing should be removed before leaving work. If contact should occur, immediately wash contaminated skin with large amounts of water. Do not eat, smoke, or drink in work areas. Cadmium nitrate presents only a moderate fire hazard (when in the form of dust) if exposed to heat, flame, or by chemical reaction with oxidizing agents, metals, hydrogen azide, zinc, selenium, or tellurium. Wear a self-contained breathing apparatus when fighting such fires. Cadmium nitrate should be stored in cool, well-ventilated areas, out of direct rays of sun, and away from combustibles and other fire hazards. Should hazardous concentrations of cadmium nitrate be released, first stop the discharge, then isolate and remove the discharged material. Before implementing land disposal of waste cadmium nitrate, consult environmental regulatory agencies for guidance.

Anwendungen & Verwendung

Cadmium salts, photographic emulsions, col- oring glass and porcelain, laboratory reagent, cad- mium salts.

Herstellung & Synthese

synthetische

reparation Cadmium nitrate is prepared by dissolving cadmium metal or its oxide, hydroxide, or carbonate, in nitric acid followed by crystallization:CdO + 2HNO3 → Cd(NO3)2 + H2O.
