What does chronic toxicity refer to?

  1. The immediate harmful effects of a substance

  2. The risk of overdose from a single application

  3. The ability of small amounts of pesticides from repeated, prolonged exposure to cause harm

  4. The comparative safety of a product over long-term use

The correct answer is: The ability of small amounts of pesticides from repeated, prolonged exposure to cause harm

Chronic toxicity refers to the potential harmful effects that can arise from exposure to small amounts of a substance over an extended period. This form of toxicity is particularly concerning when dealing with pesticides, as individuals may not recognize the cumulative effects of repeated, prolonged exposure, which can result in significant health issues. Unlike acute toxicity, which deals with the immediate effects following a single exposure or high dose, chronic toxicity emphasizes the long-term consequences of continuous low-level exposures, highlighting the importance of safety practices when handling pesticides. Understanding this concept is crucial for anyone working in pest management to ensure they minimize health risks associated with pesticide use.
