In this toxicity test, a response means death. Use the dose-response curve. At roughly what dose does 50% of the test population respond?
In this toxicity test, a response means death. Read the curve to estimate the LD50 for substance B.
In this toxicity test, a response means death. At approximately what dose does the curve indicate the LD50?
In this toxicity test, a response means death. Use the curve to identify the dose that is closest to the LD50.
In this toxicity test, a response means death. What dose on the curve corresponds most closely to an LD50?
In this toxicity test, a response means death. Estimate the LD50 from the dose-response curve.
In this test, a response means death. The curve is for substance G, while substance H has an LD50 of 55 mg/kg. Which substance is more acutely toxic?
In this test, a response means death. The curve is for substance J, while substance K has an LD50 of 45 mg/kg. Which substance is more acutely toxic?
Substance L has an LD50 of 12 mg/kg, and substance M has an LD50 of 120 mg/kg. Which is more acutely toxic?
A pesticide has an LD50 of 300 mg/kg; a second pesticide has an LD50 of 30 mg/kg. Which pesticide is more acutely toxic?
Chemical P and chemical Q each have an LD50 of 75 mg/kg in the same type of test organism and exposure route. What does this result indicate?
A substance has an LD50 of 8 mg/kg. What total dose corresponds to this mass-normalized dose for a 60 kg person?
A toxicant has an LD50 of 2.5 mg/kg. What total dose corresponds to this mass-normalized dose for a 40 kg person?
For a 20 kg organism, what total dose corresponds to an LD50 of 15 mg/kg?
A chemical's LD50 is 0.4 mg/kg. For a 50 kg organism, what total dose corresponds to that value?
A test organism has a mass of 70 kg. A substance's LD50 is 6 mg/kg. What total dose corresponds to that mass-normalized dose?
During a chemical spill, a worker inhales a high concentration of fumes during a four-hour cleanup. Is this acute or chronic exposure?
A resident drinks water containing a low concentration of a contaminant every day for eight years. Is this acute or chronic exposure?
A farmworker is exposed to a concentrated pesticide mist twice during one workday. How should this exposure be classified?
A household uses a well with arsenic contamination every day for two years. How should this exposure be classified?
