Summary of evaluation of the CMR properties
Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath
headache, nausea, and vomiting. It causes conjunctivitis leading eventually to an allergic type of reaction of the
eyes. Acute selenium poisoning produces central nervous system effects, which include nervousness, convulsions,
and drowsiness. Other signs of gastrointestinal distress, teeth that are discolored or decayed, odorous (garlic-like)
breath, and partial loss of hair and nails. Chronic exposure by inhalation can produce symptoms that include pallor,
coating of the tongue, anemia, irritation of the mucosa, lumbar pain, liver and spleen damage, as well as any of the
other previously mentioned symptoms.
