Field Evaluation of Human Exposure to Pesticides and Comparison with Exposure Assessment Models: Drone and Wide-area Sprayer Applications

Key Points

• This study evaluates human exposure to pesticides and compares it with exposure assessment models.
• Field evaluation of pesticide exposure during aerial spraying
• Comparison of data from drones and wide-area sprayers
• Use of exposure assessment models to measure spray drift
• Significant differences in human exposure levels between drone and wide-area sprayer applications
• Exposure assessment models provided varying accuracy in predicting actual human exposure
• Spray drift was noted as a critical factor affecting exposure levels
