Which of the following best defines acute toxicity?

Acute toxicity is characterized by the immediate effects that occur shortly after exposure to a toxic substance, typically within minutes to days. This contrasts with chronic toxicity, which involves health effects that develop over an extended period due to prolonged exposure or accumulation of a substance in the body. Understanding acute toxicity is essential in pesticide management, as it helps identify potential immediate health risks to applicators and the environment, guiding safety measures and response actions.
