Which type of sample would you probably NOT consider in a pesticide drift investigation?

In a pesticide drift investigation, transfer samples are typically not considered because they are used to assess the potential movement of chemicals from one surface to another in a controlled setting rather than measuring contamination as a result of drift from an aerial application. Transfer samples may include items like wipes or swabs used to assess residue left on surfaces but do not provide information about the actual exposure or contamination of plants, soil, or other environmental targets.

In contrast, whole leaf foliage and commodity samples, dislodgeable foliage samples, and clothing and surface samples are directly relevant to understanding the impacts of pesticide drift. Whole leaf and commodity samples can show the concentration of pesticide residues on the plants that may have been affected by drift, while dislodgeable foliage samples specifically measure residues that are readily removable and thus indicate immediate exposure risks. Clothing and surface samples help in evaluating potential human exposure and serve to provide evidence of drift effects on individuals or equipment in the vicinity of the application.
