Delayed effects of pesticides may result from?

1. Single exposure only

2. Repeated exposures over time

3. Both a and b

4. None of the above

The correct answer is: Both a and b

Delayed effects of pesticides can occur due to both single exposures and repeated exposures over time. When an individual is exposed to a pesticide for the first time, the effects might not be immediately observable. Instead, some pesticides can have a latency period in which the symptoms or effects develop after the initial exposure. This can occur due to the time it takes for the chemical to accumulate in the body or for physiological changes to manifest. In cases of repeated exposure, the likelihood of experiencing delayed effects may increase. Continuous or regular exposure can lead to gradual accumulation of the pesticide within the body, or it may sensitize the individual to the chemical, resulting in a delayed reaction as the body begins to exhibit adverse responses after multiple encounters with the pesticide. Understanding that both single and repeated exposures can contribute to delayed effects is crucial for recognizing the potential risks associated with pesticide use and ensuring proper safety measures are taken to minimize exposure and protect health.
