Acute toxicity refers to the harmful effects that occur shortly after exposure to a substance, typically within a very short time frame following that exposure. This could be due to a single exposure or multiple exposures within a brief period. Acute toxicity is commonly associated with chemicals and pesticides that can cause immediate health effects or reactions, such as nausea, dizziness, or even more severe consequences, depending on the dose and nature of the substance.

Understanding acute toxicity is essential because it helps determine how quickly and seriously a substance can affect health, influencing safety protocols and regulatory measures. In contrast, long-term exposure is associated with chronic toxicity, which involves adverse effects that develop over an extended duration. The other options do not accurately capture the rapid onset of effects characteristic of acute toxicity, making the identification of the correct definition crucial for safety in pesticide application and handling.
