Effects of Ricin Exposure
Ricin toxicity varies according to dose and route of exposure, however all routes appear to include a latent period in which the patient exhibits no immediate effects approximately 4 - 8 hours after exposure. Given a large enough dose, most routes of exposure will result in a terribly painful death.
Ingestion:Though ricin is not well-absorbed via oral ingestion, a systemically toxic dose will result in rather violent symptoms. These symptoms include:
Intravenous:If ricin is administered intravenously, the patient will eventually exhibit:
|
Inhalation:As with many toxins, inhalation of volatilized compounds is an effective route for quick and highly lethal administration. If ricin is inhaled, symptoms of toxicity include:
|
Skin Exposure:
According to the CDC, risk for systemic toxicity from skin exposure to ricin is very low, though absorption may occur through previously injured or irritated skin. There is a small risk for allergic reaction when ricin is exposed to uninjured skin. An allergic reaction could result in redness, blistering and pain at the site of exposure. If ricin enters the skin through an injury, such as an open laceration, the toxin could immediately enter the bloodstream resulting in the more dire effects seen in IV administration noted above.
