The purpose of this study envisaged the quantification of skin and respiratory exposures occasioned by work conditions during pesticide spraying of citrus fruits using hand gun sprayers; the evaluation of the efficiency of individual and group protection measures for the workers; the determination of workers' most exposed body regions; and the classification of work conditions, with and without the tested work-safety protection measures as recommended for the registered pesticides used to control the main pests and diseases that attack these types of trees and fruits. The AZR protection equipment proved to be the most efficient for the tractor driver, when spraying using pistol sprayers. The two sets of individual protection equipment that were checked also proved to be efficient. The most exposed regions of the tractor driver's body were the thighs, the front of the legs, the feet and hands. The most exposed regions of the individual sprayer working on foot were the hands and feet.

The objectives of this study were: a) to quantify dermal and respiratory exposure resulting from work conditions in the application of pesticides on citrus crops using a air-assisted sprayer and by preparing the spray in a tank with a capacity of2.000 L; b) to evaluate the measures of individual protection for these workers; c) to determine the areas of the worker's body most exposed; and d) to classify the work conditions with and without the protective measures tested, with regard to the occupational safety of the recommendations for the pesticides used in controlling the main pests and diseases of this crop. It was shown that for the tractor driver and sprayer operator applyng pesticides on citrus trees, the most efficient protective measures were the AZR ensemble and the Real cabin. The AZR ensemble was effective in controlling exposure of the spray preparer, because it was sufficient to turn work conditions from unsafe to safe. The area of the body most exposed under the two work conditions studied was the hands of the workers.
