AbstractObjective:to evaluate the effects of sugarcane burning on lung function and mucociliary clearance in sugarcane workers.Methods:sixteen sugarcane workers were evaluated in two sequential periods: during the non-harvest season, in April/2011, and during the sugarcane burning harvest season, in October/2011. Mean values (standard deviation) of lung function and mucociliary clearance were evaluated through spirometry and the saccharin transit time (STT) test, respectively.Results:lung function decreased %FEF25-75 [99.31 (23.79) to 86.36 (27.41); p = 0.001]; %FEV1 [92.19 (13.24) to 90.44 (12.76); p = 0.022]; and FEV1/FVC [88.62 (5.68) to 84.90 (6.47); p = 0.004] during the harvest season compared with the non-harvest season. A significant decrease was found in saccharin transit time during the harvest [3 (1) min] season compared with the non-harvest season [8 (3) min] (p < 0.001).Conclusion:sugarcane workers present a decrease in %FEF25-75, %FEV1, FEV1/FVC ratio, and increase in nasal mucociliary transport velocity at the end of the harvest season.
