While throat irritation is usually the first symptom of acute cadmium inhalation toxicity, this symptom is not enough to diagnose a patient with this condition. The other symptoms listed begin after four to 10 hours. There is also a chance that a sustained fever and noncardiac pulmonary edema can occur, reports the Agency for Toxic Substances and Disease Research. This type of exposure can result in acute hepatic and renal injury.

Patients exposed to cadmium over a long period of time have more severe symptoms. Chronic obstructive pulmonary disease and chronic renal failure are conditions that can result from prolonged exposure to cadmium. It can also cause kidney stones, lung cancer, osteomalacia, prostatic cancer and proteinuria, notes the Agency for Toxic Substances and Disease Research. Liver damage and hypertension sometimes occur in cases of chronic cadmium toxicity. There is also evidence that chronic cadmium exposure causes mild anemia, anosmia and yellowing of the teeth. While acute cadmium inhalation toxicity is unlikely to occur in North America, there is a higher chance of chronic exposure occurring through ingestion, especially in children who may eat soil contaminated with cadmium.
