Toxicity from repeated exposures to a pesticide over time is referred to as what type of toxicity?

1. Acute toxicity

2. Chronic toxicity

3. Instant toxicity

4. Late-onset toxicity

The correct answer is: Chronic toxicity

Chronic toxicity refers to the harmful effects that result from prolonged exposure to a pesticide over an extended period. This type of toxicity often develops gradually and may not present immediate symptoms, which can make it more insidious and harder to recognize compared to acute toxicity, which occurs after a single short-term exposure and typically manifests quickly. Individuals often experience a cumulative effect from repeated exposure, which can lead to long-term health issues. Understanding chronic toxicity is crucial for pesticide applicators, as it emphasizes the need for ongoing safety practices and monitoring of exposure levels to mitigate potential health risks associated with long-term pesticide use.
