Acute effects timeframe.

Acute effects timeframe.

• A. Immediately and continuously
• B. Symptoms occur after days
• C. Symptoms usually occur within minutes or hours after exposure
• D. After weeks

Answer: (C)

Acute effects are symptoms that appear very soon after exposure to a pesticide or toxic chemical, typically within a short window. The usual onset is within minutes to hours, depending on how the chemical enters the body and how quickly it is absorbed. This is why symptoms occurring within minutes or hours after exposure best describe acute effects. Choices suggesting immediate and ongoing, or onset after days or weeks, describe situations outside the typical rapid-onset timeframe (continuous or delayed effects) and aren’t what “acute” means.
