Arsenic poisoing
Harmful effects of arsenic compounds (in pesticides,
chemotherapy drugs, paints, etc.), most often from insecticide exposure.
Susceptibility varies. Arsenic is believed to combine with
certain enzymes, interfering with cellular metabolism. Symptoms of acute
arsenic poisoning include nausea and abdominal pain followed by circulatory
collapse. Acute exposure to the gas arsine causes destruction of red blood
cells and kidney damage; chronic exposure causes weakness, skin disorders,
anemia, and nervous-system disorders. Arsenic in urine and hair or nails is the
key to diagnosis. Treatment involves washing out the stomach and promptly administering
the antidote dimercaprol.
