How is exposure to pesticides defined?

Exposure to pesticides is defined as any contact an individual has with a pesticide. This encompasses a wide range of scenarios, including direct applications of pesticides as well as situations where a person might come into contact with surfaces or environments that have been treated. This definition emphasizes the importance of considering not only the application of pesticides but also how they may affect individuals who may inadvertently or directly come into contact with them afterward.

Contact with pesticide residue after application is a specific subset of exposure but does not capture the full scope of what exposure entails. Mixing pesticides with other chemicals can lead to different reactions or effects, but this process alone does not define exposure. Similarly, breaches of legal guidelines can indicate unsafe practices but do not directly define exposure to the pesticide itself. Understanding the broad definition of exposure is crucial for safety, risk assessment, and implementing appropriate protective measures when working with or near pesticides.
