What does oral toxicity refer to in the context of pesticides?

Oral toxicity specifically refers to the potential of a pesticide to induce harmful effects when ingested. This measure is crucial for evaluating the safety of pesticides, especially in terms of exposure risks to humans, animals, and non-target organisms. Understanding oral toxicity helps pesticide users assess the dangers posed by chemical products and guides regulatory decisions. In contrast to other choices, which address different aspects of pesticide interaction, the correct answer focuses solely on the impact of ingestion, reflecting the direct relationship between the substance and potential health risks caused by oral exposure.
