What factor determines the hazard associated with a pesticide?

The hazard associated with a pesticide is primarily determined by the exposure level and toxicity. Exposure level refers to the amount and duration of contact that people, animals, or the environment have with the pesticide. Toxicity is a measure of how harmful a substance can be, based on its chemical properties and the potential physiological effects it has on organisms.

When considering both exposure and toxicity, it becomes clear how they together inform the overall hazard. For instance, a pesticide with low toxicity can still pose a significant hazard if individuals are exposed at high levels or for extended periods. Conversely, a highly toxic pesticide may pose a reduced hazard if exposure is limited, such as through proper application methods and protective gear.

Understanding the interplay between these factors is essential for assessing risks and implementing effective safety measures in the use of pesticides.
