Acute arsenic poisoning from ingestion results in marked irritation of the stomach and intestines with

nausea, vomiting and diarrhea. In severe cases, the vomitus and stools are bloody and the patient

goes into collapse and shock with weak, rapid pulse, cold sweats, coma and death.

Chronic arsenic poisoning may cause disturbances of the digestive system such as loss of appetite,

cramps, nausea, constipation or diarrhea.

Selenium may cause amyotrophic lateral sclerosis, bronchial irritation, gastrointestinal distress,

vasopharyngeal irritation, garlic odor on breath and sweat, metallic taste, pallor, irritability, excessive

fatigue, loss of fingernails and hair, pulmonary edema, anemia and weight loss.

Subacute to chronic toxicity: No effects known.
