Resumen:
Eight experiments were done with four different operators, under typical field conditions with a lever operated backpack sprayer. The methodology applied is based on the Whole Body Dosimetry technique, evaluating a set of different data for the mix and load, application and re-entry operations. These results indicated that the PDE of the application step was (38 ±17) mL.h-1 with the highest proportion on torso, head and arms. When the three stages were compared, re-entry was found to contribute least towards the total PDE; meanwhile in all cases, except one, the mix/load operation was the stage with highest exposure. The Margin of Safety (MOS) for each different operation was also calculated and the preliminary results of pesticide drift from the greenhouse to the environment are presented. These preliminary results emphasize the importance of improving the personal protection measures in the mix and load stage, an operation that is not usually associated with high-risk in small production units.
