What is the definition of exposure in relation to pesticides?

Exposure in relation to pesticides refers to the amount of contact an individual (human, animal, or other organisms) has with pesticides through various means, such as inhalation, skin absorption, or ingestion. This definition encompasses not just the initial contact but also the different pathways through which exposure can occur.

Understanding exposure is crucial when assessing the risks associated with pesticide use, as it helps determine the possible health effects based on how much and how often someone comes into contact with the pesticide. The concept highlights that exposure can take many forms and is not solely defined by the toxicity of the pesticide itself.

In contrast, defining exposure as the measure of toxicity, the duration of pesticide use, or simply the visibility and odor of a pesticide does not capture the multifaceted nature of how individuals may actually come into contact with harmful substances. Focusing specifically on the amount of contact reinforces the importance of monitoring and managing pesticide exposure to protect health and safety.
