3. These "death cap" mushrooms are hazardous because they contain toxins (amanita toxins or amatoxins). Ingestion of a handful of mushrooms contains about 20 mg of toxin, and is sufficient to kill an average size human (170 lbs) in 12-24 hours. a. Estimate the LD50 value from the above data (show work) b. Is this an example of acute or chronic toxicity? c. Are amatoxins considered extremely toxic, highly toxic, moderately toxic, slightly toxic or harmless (based on the Hodge and Sterner Scale, Table 1 in link here) 3.
