Acute toxicity describes which type of effects?

• A. Short-term exposure effects
• B. Long-term exposure effects
• C. LD50
• D. PPE

Answer: (A)

Acute toxicity describes adverse effects that occur soon after exposure, typically from a single exposure or a brief period of exposure, with rapid onset and potential severity. This is different from chronic toxicity, which results from long-term or repeated exposure over extended times. The LD50 value is a statistical measure used to express how toxic a substance is by indicating the dose that kills 50% of test animals; it’s a way to quantify toxicity, not the description of acute effects itself. PPE stands for personal protective equipment, which helps prevent exposure but doesn’t define the timing or nature of the toxic effects.
