Cadmium Compounds
Exposure to sufficiently high concentrations of cadmium dusts may result in upper respiratory
tract irritation with delayed symptoms of cough, sore throat, wheezing, headache, chest pain,
Acute Inhalation: dizziness, abdominal pain, nausea, diarrhea and vomiting. Exposure may also cause sweating,
chills, and difficulty in breathing. Severe exposures may result in lung, kidney or liver damage
or death from massive pulmonary edema.
Cadmium is highly cumulative and respiratory effects from repeated or prolonged exposure to
dusts or fumes may include rhinitis, bronchitis, emphysema, cough, dyspnea, abnormal lung
function, obstructive disease, and possibly fibrosis. Ulceration of the nasal septum and yellow
discoloration of the teeth may occur. Cadmium induced kidney damage is irreversible and
may progress after exposure ceases; some cases of progression to kidney failure have been
described. Osteomalacia, osteoporosis, and spontaneous and pseudofractures may occur and
Chronic Inhalation: may be manifested as back pain, pain in the extremities, difficulty in walking, and pain on bone
pressure. Other effects may include irritability, weight loss, fatigue, mild to moderate anemia,
eosinophilia, damage to the olfactory nerve with anosmia, and liver damage. An epidemiologi-
cal study suggests a relationship between cadmium levels in air and cardiovascular disease,
but a causal association has not been proved. Occupational exposure to cadmium is implicated
in a significant increase in the incidence of prostatic and respiratory cancers.
The persistent vomiting induced by cadmium compounds may limit the amount retained, but if
sufficient amounts are absorbed, symptoms of systemic toxicity may begin within 15 minutes
to 2 hours. Salivation, choking, severe nausea, abdominal pain, diarrhea, tenesmus, blurred
vision, dizziness, headache, muscular cramps, exhaustion, collapse, shock, unconsciousness
Acute Ingestion of Cadmium
and rarely, convulsions may occur. Recovery may begin within 5-10 hours; sequelae may
Compounds: include delayed liver and kidney damage. Single doses of 10-20 mg of soluble cadmium salts
have induced severe toxic effects and doses above 300 mg may be fatal. Death due to shock
and dehydration may occur within 24 hours or may be delayed 7-14 days and be due to renal
failure or cardiopulmonary depression.
Chronic Ingestion of Cad- Cadmium accumulates in the body and prolonged low level exposure may cause irreversible
renal tubular dysfunction and bone effects as described in the chronic inhalation section.

Acute Ingestion: taste in the mouth, tachycardia, chills, and central nervous system effects as detailed in acute

Repeated or prolonged ingestion may result in a metallic taste in the mouth, garlic odor of

reported from ingestion of food and water containing excessive amounts of selenium include
skin hyperpigmentation, nail changes, gingivitis, excess dental caries, malocclusion, weight
Chronic Ingestion: loss, vestibulotoxicity, amyotrophic lateral sclerosis, arthritis, problems walking, diminished
reflexes, substernal pain, disturbances of respiratory and endocrine function, jaundice, hepatic
disease, and socio-psychologic effects. In extreme cases, loss of nails and hair, numbness and
incoordination of arms and legs, paralysis, lack of mental alertness and death from respiratory
paralysis may occur.
