What is the purpose of a buffer zone in pesticide application?

The purpose of a buffer zone in pesticide application primarily revolves around protecting human health and safety. A buffer zone is defined as a designated area surrounding a pesticide application site where specific activities are restricted or prohibited. This practice helps minimize the risk of pesticide drift, which can lead to unintended exposure for people, animals, and sensitive environments.

By establishing buffer zones, regulatory agencies ensure that there is a safe distance between the area where pesticides are applied and locations where people may be present, such as residential areas, schools, or water bodies. This protective measure helps to safeguard public health by preventing accidental exposure to chemicals that may pose health risks.

The option that addresses the function of buffer zones in the context of human health and safety effectively encapsulates why they are implemented during pesticide application.
