Which statement best describes symptoms of acute pesticide toxicity?

• A. Symptoms will always occur only after repeated exposures over months.
• B. Symptoms are not related to dose.
• C. Symptoms that may result from a single or multiple doses within 24 hours.
• D. There are no symptoms associated with acute toxicity.

Answer: (C)

Acute pesticide toxicity shows up quickly after exposure, often within 24 hours. Symptoms can arise after a single high dose or after several smaller doses in a short period, reflecting a rapid onset of effects. The key idea is that the timing of symptoms is tied to the dose and the short time frame after exposure, not to months of exposure or to a lack of relationship with dose. So an exposure event within a day can produce noticeable symptoms, whereas chronic toxicity involves longer-term exposure and gradual effects. The other statements misstate the timing, the role of dose, or the existence of symptoms, whereas acute toxicity is defined by symptoms appearing within 24 hours after exposure.
