Which of the following is NOT a way pesticides can move offsite?

Soil erosion typically refers to the process of soil being carried away by wind or water, but it doesn't directly describe the mechanism through which pesticides move offsite. While pesticides can indeed become associated with soil particles and thereby be transported when soil erodes, the question specifically addresses the direct movement of pesticides rather than the indirect association with soil. In this context, pesticide movement is typically understood in relation to more immediate methods such as being transported by wind, carried away by water runoff, or attaching to objects or organisms. Therefore, identifying soil erosion as a process not directly responsible for the movement of pesticides offsite aligns with the understanding of these mechanisms.
